+<p>Welcome to the “Implementing a language with LLVM” tutorial. This
+tutorial runs through the implementation of a simple language, showing
+how fun and easy it can be. This tutorial will get you up and started as
+well as help to build a framework you can extend to other languages. The
+code in this tutorial can also be used as a playground to hack on other
+LLVM specific things.</p>
+<p>The goal of this tutorial is to progressively unveil our language,
+describing how it is built up over time. This will let us cover a fairly
+broad range of language design and LLVM-specific usage issues, showing
+and explaining the code for it all along the way, without overwhelming
+you with tons of details up front.</p>
+<p>It is useful to point out ahead of time that this tutorial is really
+about teaching compiler techniques and LLVM specifically, <em>not</em> about
+teaching modern and sane software engineering principles. In practice,
+this means that we’ll take a number of shortcuts to simplify the
+exposition. For example, the code leaks memory, uses global variables
+all over the place, doesn’t use nice design patterns like
+<a class="reference external" href="http://en.wikipedia.org/wiki/Visitor_pattern">visitors</a>, etc... but
+it is very simple. If you dig in and use the code as a basis for future
+projects, fixing these deficiencies shouldn’t be hard.</p>
+<p>I’ve tried to put this tutorial together in a way that makes chapters
+easy to skip over if you are already familiar with or are uninterested
+in the various pieces. The structure of the tutorial is:</p>
+<ul class="simple">
+<li><a class="reference external" href="#language">Chapter #1</a>: Introduction to the Kaleidoscope
+language, and the definition of its Lexer - This shows where we are
+going and the basic functionality that we want it to do. In order to
+make this tutorial maximally understandable and hackable, we choose
+to implement everything in C++ instead of using lexer and parser
+generators. LLVM obviously works just fine with such tools, feel free
+to use one if you prefer.</li>
+<li><a class="reference external" href="LangImpl2.html">Chapter #2</a>: Implementing a Parser and AST -
+With the lexer in place, we can talk about parsing techniques and
+basic AST construction. This tutorial describes recursive descent
+parsing and operator precedence parsing. Nothing in Chapters 1 or 2
+is LLVM-specific, the code doesn’t even link in LLVM at this point.
+:)</li>
+<li><a class="reference external" href="LangImpl3.html">Chapter #3</a>: Code generation to LLVM IR - With
+the AST ready, we can show off how easy generation of LLVM IR really
+is.</li>
+<li><a class="reference external" href="LangImpl4.html">Chapter #4</a>: Adding JIT and Optimizer Support
+- Because a lot of people are interested in using LLVM as a JIT,
+we’ll dive right into it and show you the 3 lines it takes to add JIT
+support. LLVM is also useful in many other ways, but this is one
+simple and “sexy” way to show off its power. :)</li>
+<li><a class="reference external" href="LangImpl5.html">Chapter #5</a>: Extending the Language: Control
+Flow - With the language up and running, we show how to extend it
+with control flow operations (if/then/else and a ‘for’ loop). This
+gives us a chance to talk about simple SSA construction and control
+flow.</li>
+<li><a class="reference external" href="LangImpl6.html">Chapter #6</a>: Extending the Language:
+User-defined Operators - This is a silly but fun chapter that talks
+about extending the language to let the user program define their own
+arbitrary unary and binary operators (with assignable precedence!).
+This lets us build a significant piece of the “language” as library
+routines.</li>
+<li><a class="reference external" href="LangImpl7.html">Chapter #7</a>: Extending the Language: Mutable
+Variables - This chapter talks about adding user-defined local
+variables along with an assignment operator. The interesting part
+about this is how easy and trivial it is to construct SSA form in
+LLVM: no, LLVM does <em>not</em> require your front-end to construct SSA
+form!</li>
+<li><a class="reference external" href="LangImpl8.html">Chapter #8</a>: Conclusion and other useful LLVM
+tidbits - This chapter wraps up the series by talking about
+potential ways to extend the language, but also includes a bunch of
+pointers to info about “special topics” like adding garbage
+collection support, exceptions, debugging, support for “spaghetti
+stacks”, and a bunch of other tips and tricks.</li>
+</ul>
+<p>By the end of the tutorial, we’ll have written a bit less than 700 lines
+of non-comment, non-blank, lines of code. With this small amount of
+code, we’ll have built up a very reasonable compiler for a non-trivial
+language including a hand-written lexer, parser, AST, as well as code
+generation support with a JIT compiler. While other systems may have
+interesting “hello world” tutorials, I think the breadth of this
+tutorial is a great testament to the strengths of LLVM and why you
+should consider it if you’re interested in language or compiler design.</p>
+<p>A note about this tutorial: we expect you to extend the language and
+play with it on your own. Take the code and go crazy hacking away at it,
+compilers don’t need to be scary creatures - it can be a lot of fun to
+play with languages!</p>

+<h2><a class="toc-backref" href="#id2">1.2. The Basic Language</a><a class="headerlink" href="#the-basic-language" title="Permalink to this headline">¶</a></h2>
+<p>This tutorial will be illustrated with a toy language that we’ll call
+“<a class="reference external" href="http://en.wikipedia.org/wiki/Kaleidoscope">Kaleidoscope</a>” (derived
+from “meaning beautiful, form, and view”). Kaleidoscope is a procedural
+language that allows you to define functions, use conditionals, math,
+etc. Over the course of the tutorial, we’ll extend Kaleidoscope to
+support the if/then/else construct, a for loop, user defined operators,
+JIT compilation with a simple command line interface, etc.</p>
+<p>Because we want to keep things simple, the only datatype in Kaleidoscope
+is a 64-bit floating point type (aka ‘double’ in C parlance). As such,
+all values are implicitly double precision and the language doesn’t
+require type declarations. This gives the language a very nice and
+simple syntax. For example, the following simple example computes
+<a class="reference external" href="http://en.wikipedia.org/wiki/Fibonacci_number">Fibonacci numbers:</a></p>
+<div class="highlight-python"><pre># Compute the x'th fibonacci number.
+def fib(x)
+ if x < 3 then
+ 1
+ else
+ fib(x-1)+fib(x-2)
+
+# This expression will compute the 40th number.
+fib(40)</pre>
+</div>
+<p>We also allow Kaleidoscope to call into standard library functions (the
+LLVM JIT makes this completely trivial). This means that you can use the
+‘extern’ keyword to define a function before you use it (this is also
+useful for mutually recursive functions). For example:</p>
+<div class="highlight-python"><pre>extern sin(arg);
+extern cos(arg);
+extern atan2(arg1 arg2);
+
+atan2(sin(.4), cos(42))</pre>
+</div>
+<p>A more interesting example is included in Chapter 6 where we write a
+little Kaleidoscope application that <a class="reference external" href="LangImpl6.html#example">displays a Mandelbrot
+Set</a> at various levels of magnification.</p>
+<p>Lets dive into the implementation of this language!</p>
+</div>
+<div class="section" id="the-lexer">
+<h2><a class="toc-backref" href="#id3">1.3. The Lexer</a><a class="headerlink" href="#the-lexer" title="Permalink to this headline">¶</a></h2>
+<p>When it comes to implementing a language, the first thing needed is the
+ability to process a text file and recognize what it says. The
+traditional way to do this is to use a
+“<a class="reference external" href="http://en.wikipedia.org/wiki/Lexical_analysis">lexer</a>” (aka
+‘scanner’) to break the input up into “tokens”. Each token returned by
+the lexer includes a token code and potentially some metadata (e.g. the
+numeric value of a number). First, we define the possibilities:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">// The lexer returns tokens [0-255] if it is an unknown character, otherwise one</span>
+<span class="c1">// of these for known things.</span>
+<span class="k">enum</span> <span class="n">Token</span> <span class="p">{</span>
+ <span class="n">tok_eof</span> <span class="o">=</span> <span class="o">-</span><span class="mi">1</span><span class="p">,</span>
+
+ <span class="c1">// commands</span>
+ <span class="n">tok_def</span> <span class="o">=</span> <span class="o">-</span><span class="mi">2</span><span class="p">,</span> <span class="n">tok_extern</span> <span class="o">=</span> <span class="o">-</span><span class="mi">3</span><span class="p">,</span>
+
+ <span class="c1">// primary</span>
+ <span class="n">tok_identifier</span> <span class="o">=</span> <span class="o">-</span><span class="mi">4</span><span class="p">,</span> <span class="n">tok_number</span> <span class="o">=</span> <span class="o">-</span><span class="mi">5</span><span class="p">,</span>
+<span class="p">};</span>
+
+<span class="k">static</span> <span class="n">std</span><span class="o">::</span><span class="n">string</span> <span class="n">IdentifierStr</span><span class="p">;</span> <span class="c1">// Filled in if tok_identifier</span>
+<span class="k">static</span> <span class="kt">double</span> <span class="n">NumVal</span><span class="p">;</span> <span class="c1">// Filled in if tok_number</span>
+</pre></div>
+</div>
+<p>Each token returned by our lexer will either be one of the Token enum
+values or it will be an ‘unknown’ character like ‘+’, which is returned
+as its ASCII value. If the current token is an identifier, the
+<tt class="docutils literal"><span class="pre">IdentifierStr</span></tt> global variable holds the name of the identifier. If
+the current token is a numeric literal (like 1.0), <tt class="docutils literal"><span class="pre">NumVal</span></tt> holds its
+value. Note that we use global variables for simplicity, this is not the
+best choice for a real language implementation :).</p>
+<p>The actual implementation of the lexer is a single function named
+<tt class="docutils literal"><span class="pre">gettok</span></tt>. The <tt class="docutils literal"><span class="pre">gettok</span></tt> function is called to return the next token
+from standard input. Its definition starts as:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// gettok - Return the next token from standard input.</span>
+<span class="k">static</span> <span class="kt">int</span> <span class="nf">gettok</span><span class="p">()</span> <span class="p">{</span>
+ <span class="k">static</span> <span class="kt">int</span> <span class="n">LastChar</span> <span class="o">=</span> <span class="sc">' '</span><span class="p">;</span>
+
+ <span class="c1">// Skip any whitespace.</span>
+ <span class="k">while</span> <span class="p">(</span><span class="n">isspace</span><span class="p">(</span><span class="n">LastChar</span><span class="p">))</span>
+ <span class="n">LastChar</span> <span class="o">=</span> <span class="n">getchar</span><span class="p">();</span>
+</pre></div>
+</div>
+<p><tt class="docutils literal"><span class="pre">gettok</span></tt> works by calling the C <tt class="docutils literal"><span class="pre">getchar()</span></tt> function to read
+characters one at a time from standard input. It eats them as it
+recognizes them and stores the last character read, but not processed,
+in LastChar. The first thing that it has to do is ignore whitespace
+between tokens. This is accomplished with the loop above.</p>
+<p>The next thing <tt class="docutils literal"><span class="pre">gettok</span></tt> needs to do is recognize identifiers and
+specific keywords like “def”. Kaleidoscope does this with this simple
+loop:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="k">if</span> <span class="p">(</span><span class="n">isalpha</span><span class="p">(</span><span class="n">LastChar</span><span class="p">))</span> <span class="p">{</span> <span class="c1">// identifier: [a-zA-Z][a-zA-Z0-9]*</span>
+ <span class="n">IdentifierStr</span> <span class="o">=</span> <span class="n">LastChar</span><span class="p">;</span>
+ <span class="k">while</span> <span class="p">(</span><span class="n">isalnum</span><span class="p">((</span><span class="n">LastChar</span> <span class="o">=</span> <span class="n">getchar</span><span class="p">())))</span>
+ <span class="n">IdentifierStr</span> <span class="o">+=</span> <span class="n">LastChar</span><span class="p">;</span>
+
+ <span class="k">if</span> <span class="p">(</span><span class="n">IdentifierStr</span> <span class="o">==</span> <span class="s">"def"</span><span class="p">)</span> <span class="k">return</span> <span class="n">tok_def</span><span class="p">;</span>
+ <span class="k">if</span> <span class="p">(</span><span class="n">IdentifierStr</span> <span class="o">==</span> <span class="s">"extern"</span><span class="p">)</span> <span class="k">return</span> <span class="n">tok_extern</span><span class="p">;</span>
+ <span class="k">return</span> <span class="n">tok_identifier</span><span class="p">;</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Note that this code sets the ‘<tt class="docutils literal"><span class="pre">IdentifierStr</span></tt>‘ global whenever it
+lexes an identifier. Also, since language keywords are matched by the
+same loop, we handle them here inline. Numeric values are similar:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="k">if</span> <span class="p">(</span><span class="n">isdigit</span><span class="p">(</span><span class="n">LastChar</span><span class="p">)</span> <span class="o">||</span> <span class="n">LastChar</span> <span class="o">==</span> <span class="sc">'.'</span><span class="p">)</span> <span class="p">{</span> <span class="c1">// Number: [0-9.]+</span>
+ <span class="n">std</span><span class="o">::</span><span class="n">string</span> <span class="n">NumStr</span><span class="p">;</span>
+ <span class="k">do</span> <span class="p">{</span>
+ <span class="n">NumStr</span> <span class="o">+=</span> <span class="n">LastChar</span><span class="p">;</span>
+ <span class="n">LastChar</span> <span class="o">=</span> <span class="n">getchar</span><span class="p">();</span>
+ <span class="p">}</span> <span class="k">while</span> <span class="p">(</span><span class="n">isdigit</span><span class="p">(</span><span class="n">LastChar</span><span class="p">)</span> <span class="o">||</span> <span class="n">LastChar</span> <span class="o">==</span> <span class="sc">'.'</span><span class="p">);</span>
+
+ <span class="n">NumVal</span> <span class="o">=</span> <span class="n">strtod</span><span class="p">(</span><span class="n">NumStr</span><span class="p">.</span><span class="n">c_str</span><span class="p">(),</span> <span class="mi">0</span><span class="p">);</span>
+ <span class="k">return</span> <span class="n">tok_number</span><span class="p">;</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>This is all pretty straight-forward code for processing input. When
+reading a numeric value from input, we use the C <tt class="docutils literal"><span class="pre">strtod</span></tt> function to
+convert it to a numeric value that we store in <tt class="docutils literal"><span class="pre">NumVal</span></tt>. Note that
+this isn’t doing sufficient error checking: it will incorrectly read
+“1.23.45.67” and handle it as if you typed in “1.23”. Feel free to
+extend it :). Next we handle comments:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="k">if</span> <span class="p">(</span><span class="n">LastChar</span> <span class="o">==</span> <span class="sc">'#'</span><span class="p">)</span> <span class="p">{</span>
+ <span class="c1">// Comment until end of line.</span>
+ <span class="k">do</span> <span class="n">LastChar</span> <span class="o">=</span> <span class="n">getchar</span><span class="p">();</span>
+ <span class="k">while</span> <span class="p">(</span><span class="n">LastChar</span> <span class="o">!=</span> <span class="n">EOF</span> <span class="o">&&</span> <span class="n">LastChar</span> <span class="o">!=</span> <span class="sc">'\n'</span> <span class="o">&&</span> <span class="n">LastChar</span> <span class="o">!=</span> <span class="sc">'\r'</span><span class="p">);</span>
+
+ <span class="k">if</span> <span class="p">(</span><span class="n">LastChar</span> <span class="o">!=</span> <span class="n">EOF</span><span class="p">)</span>
+ <span class="k">return</span> <span class="n">gettok</span><span class="p">();</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>We handle comments by skipping to the end of the line and then return
+the next token. Finally, if the input doesn’t match one of the above
+cases, it is either an operator character like ‘+’ or the end of the
+file. These are handled with this code:</p>
+<div class="highlight-c++"><div class="highlight"><pre> <span class="c1">// Check for end of file. Don't eat the EOF.</span>
+ <span class="k">if</span> <span class="p">(</span><span class="n">LastChar</span> <span class="o">==</span> <span class="n">EOF</span><span class="p">)</span>
+ <span class="k">return</span> <span class="n">tok_eof</span><span class="p">;</span>
+
+ <span class="c1">// Otherwise, just return the character as its ascii value.</span>
+ <span class="kt">int</span> <span class="n">ThisChar</span> <span class="o">=</span> <span class="n">LastChar</span><span class="p">;</span>
+ <span class="n">LastChar</span> <span class="o">=</span> <span class="n">getchar</span><span class="p">();</span>
+ <span class="k">return</span> <span class="n">ThisChar</span><span class="p">;</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>With this, we have the complete lexer for the basic Kaleidoscope
+language (the <a class="reference external" href="LangImpl2.html#code">full code listing</a> for the Lexer
+is available in the <a class="reference external" href="LangImpl2.html">next chapter</a> of the tutorial).
+Next we’ll <a class="reference external" href="LangImpl2.html">build a simple parser that uses this to build an Abstract
+Syntax Tree</a>. When we have that, we’ll include a
+driver so that you can use the lexer and parser together.</p>

+<p>Welcome to Chapter 2 of the “<a class="reference external" href="index.html">Implementing a language with
+LLVM</a>” tutorial. This chapter shows you how to use the

+<a class="reference external" href="http://en.wikipedia.org/wiki/Parsing">parser</a> for our Kaleidoscope

+Syntax Tree</a> (AST).</p>
+<p>The parser we will build uses a combination of <a class="reference external" href="http://en.wikipedia.org/wiki/Recursive_descent_parser">Recursive Descent

+<a class="reference external" href="http://en.wikipedia.org/wiki/Operator-precedence_parser">Operator-Precedence

+<p>The AST for a program captures its behavior in such a way that it is
+easy for later stages of the compiler (e.g. code generation) to
+interpret. We basically want one object for each construct in the

+<p>The code above shows the definition of the base ExprAST class and one
+subclass which we use for numeric literals. The important thing to note
+about this code is that the NumberExprAST class captures the numeric
+value of the literal as an instance variable. This allows later phases
+of the compiler to know what the stored numeric value is.</p>
+<p>Right now we only create the AST, so there are no useful accessor
+methods on them. It would be very easy to add a virtual method to pretty
+print the code, for example. Here are the other expression AST node
+definitions that we’ll use in the basic form of the Kaleidoscope

+<p>This is all (intentionally) rather straight-forward: variables capture
+the variable name, binary operators capture their opcode (e.g. ‘+’), and
+calls capture a function name as well as a list of any argument
+expressions. One thing that is nice about our AST is that it captures
+the language features without talking about the syntax of the language.
+Note that there is no discussion about precedence of binary operators,
+lexical structure, etc.</p>
+<p>For our basic language, these are all of the expression nodes we’ll
+define. Because it doesn’t have conditional control flow, it isn’t
+Turing-complete; we’ll fix that in a later installment. The two things

+<p>In Kaleidoscope, functions are typed with just a count of their
+arguments. Since all values are double precision floating point, the
+type of each argument doesn’t need to be stored anywhere. In a more
+aggressive and realistic language, the “ExprAST” class would probably
+have a type field.</p>
+<p>With this scaffolding, we can now talk about parsing expressions and

+<p>Now that we have an AST to build, we need to define the parser code to
+build it. The idea here is that we want to parse something like “x+y”
+(which is returned as three tokens by the lexer) into an AST that could
+be generated with calls like this:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="n">ExprAST</span> <span class="o">*</span><span class="n">X</span> <span class="o">=</span> <span class="k">new</span> <span class="n">VariableExprAST</span><span class="p">(</span><span class="s">"x"</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>In order to do this, we’ll start by defining some basic helper routines:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// CurTok/getNextToken - Provide a simple token buffer. CurTok is the current</span>
+<span class="c1">/// token the parser is looking at. getNextToken reads another token from the</span>
+<span class="c1">/// lexer and updates CurTok with its results.</span>
+<span class="k">static</span> <span class="kt">int</span> <span class="n">CurTok</span><span class="p">;</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>This implements a simple token buffer around the lexer. This allows us
+to look one token ahead at what the lexer is returning. Every function
+in our parser will assume that CurTok is the current token that needs to
+be parsed.</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// Error* - These are little helper functions for error handling.</span>

+</pre></div>
+</div>
+<p>The <tt class="docutils literal"><span class="pre">Error</span></tt> routines are simple helper routines that our parser will
+use to handle errors. The error recovery in our parser will not be the
+best and is not particular user-friendly, but it will be enough for our
+tutorial. These routines make it easier to handle errors in routines
+that have various return types: they always return null.</p>
+<p>With these basic helper functions, we can implement the first piece of
+our grammar: numeric literals.</p>
+</div>
+<div class="section" id="basic-expression-parsing">
+<h2><a class="toc-backref" href="#id5">2.4. Basic Expression Parsing</a><a class="headerlink" href="#basic-expression-parsing" title="Permalink to this headline">¶</a></h2>
+<p>We start with numeric literals, because they are the simplest to
+process. For each production in our grammar, we’ll define a function
+which parses that production. For numeric literals, we have:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// numberexpr ::= number</span>
+<span class="k">static</span> <span class="n">ExprAST</span> <span class="o">*</span><span class="nf">ParseNumberExpr</span><span class="p">()</span> <span class="p">{</span>
+ <span class="n">ExprAST</span> <span class="o">*</span><span class="n">Result</span> <span class="o">=</span> <span class="k">new</span> <span class="n">NumberExprAST</span><span class="p">(</span><span class="n">NumVal</span><span class="p">);</span>
+ <span class="n">getNextToken</span><span class="p">();</span> <span class="c1">// consume the number</span>
+ <span class="k">return</span> <span class="n">Result</span><span class="p">;</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>This routine is very simple: it expects to be called when the current
+token is a <tt class="docutils literal"><span class="pre">tok_number</span></tt> token. It takes the current number value,
+creates a <tt class="docutils literal"><span class="pre">NumberExprAST</span></tt> node, advances the lexer to the next token,
+and finally returns.</p>
+<p>There are some interesting aspects to this. The most important one is
+that this routine eats all of the tokens that correspond to the
+production and returns the lexer buffer with the next token (which is
+not part of the grammar production) ready to go. This is a fairly
+standard way to go for recursive descent parsers. For a better example,
+the parenthesis operator is defined like this:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// parenexpr ::= '(' expression ')'</span>
+<span class="k">static</span> <span class="n">ExprAST</span> <span class="o">*</span><span class="nf">ParseParenExpr</span><span class="p">()</span> <span class="p">{</span>
+ <span class="n">getNextToken</span><span class="p">();</span> <span class="c1">// eat (.</span>
+ <span class="n">ExprAST</span> <span class="o">*</span><span class="n">V</span> <span class="o">=</span> <span class="n">ParseExpression</span><span class="p">();</span>
+ <span class="k">if</span> <span class="p">(</span><span class="o">!</span><span class="n">V</span><span class="p">)</span> <span class="k">return</span> <span class="mi">0</span><span class="p">;</span>
+
+ <span class="k">if</span> <span class="p">(</span><span class="n">CurTok</span> <span class="o">!=</span> <span class="sc">')'</span><span class="p">)</span>
+ <span class="k">return</span> <span class="n">Error</span><span class="p">(</span><span class="s">"expected ')'"</span><span class="p">);</span>
+ <span class="n">getNextToken</span><span class="p">();</span> <span class="c1">// eat ).</span>
+ <span class="k">return</span> <span class="n">V</span><span class="p">;</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>This function illustrates a number of interesting things about the
+parser:</p>
+<p>1) It shows how we use the Error routines. When called, this function
+expects that the current token is a ‘(‘ token, but after parsing the
+subexpression, it is possible that there is no ‘)’ waiting. For example,
+if the user types in “(4 x” instead of “(4)”, the parser should emit an
+error. Because errors can occur, the parser needs a way to indicate that
+they happened: in our parser, we return null on an error.</p>
+<p>2) Another interesting aspect of this function is that it uses recursion
+by calling <tt class="docutils literal"><span class="pre">ParseExpression</span></tt> (we will soon see that
+<tt class="docutils literal"><span class="pre">ParseExpression</span></tt> can call <tt class="docutils literal"><span class="pre">ParseParenExpr</span></tt>). This is powerful
+because it allows us to handle recursive grammars, and keeps each
+production very simple. Note that parentheses do not cause construction
+of AST nodes themselves. While we could do it this way, the most
+important role of parentheses are to guide the parser and provide
+grouping. Once the parser constructs the AST, parentheses are not
+needed.</p>
+<p>The next simple production is for handling variable references and
+function calls:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// identifierexpr</span>
+<span class="c1">/// ::= identifier</span>

+<p>This routine follows the same style as the other routines. (It expects
+to be called if the current token is a <tt class="docutils literal"><span class="pre">tok_identifier</span></tt> token). It
+also has recursion and error handling. One interesting aspect of this is
+that it uses <em>look-ahead</em> to determine if the current identifier is a
+stand alone variable reference or if it is a function call expression.
+It handles this by checking to see if the token after the identifier is
+a ‘(‘ token, constructing either a <tt class="docutils literal"><span class="pre">VariableExprAST</span></tt> or
+<tt class="docutils literal"><span class="pre">CallExprAST</span></tt> node as appropriate.</p>
+<p>Now that we have all of our simple expression-parsing logic in place, we
+can define a helper function to wrap it together into one entry point.
+We call this class of expressions “primary” expressions, for reasons
+that will become more clear <a class="reference external" href="LangImpl6.html#unary">later in the
+tutorial</a>. In order to parse an arbitrary
+primary expression, we need to determine what sort of expression it is:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// primary</span>
+<span class="c1">/// ::= identifierexpr</span>
+<span class="c1">/// ::= numberexpr</span>
+<span class="c1">/// ::= parenexpr</span>
+<span class="k">static</span> <span class="n">ExprAST</span> <span class="o">*</span><span class="nf">ParsePrimary</span><span class="p">()</span> <span class="p">{</span>
+ <span class="k">switch</span> <span class="p">(</span><span class="n">CurTok</span><span class="p">)</span> <span class="p">{</span>
+ <span class="nl">default:</span> <span class="k">return</span> <span class="n">Error</span><span class="p">(</span><span class="s">"unknown token when expecting an expression"</span><span class="p">);</span>
+ <span class="k">case</span> <span class="n">tok_identifier</span>: <span class="k">return</span> <span class="n">ParseIdentifierExpr</span><span class="p">();</span>

+ <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Now that you see the definition of this function, it is more obvious why
+we can assume the state of CurTok in the various functions. This uses
+look-ahead to determine which sort of expression is being inspected, and
+then parses it with a function call.</p>
+<p>Now that basic expressions are handled, we need to handle binary
+expressions. They are a bit more complex.</p>

+often ambiguous. For example, when given the string “x+y*z”, the parser
+can choose to parse it as either “(x+y)*z” or “x+(y*z)”. With common
+definitions from mathematics, we expect the later parse, because “*”
+(multiplication) has higher <em>precedence</em> than “+” (addition).</p>
+<p>There are many ways to handle this, but an elegant and efficient way is
+to use <a class="reference external" href="http://en.wikipedia.org/wiki/Operator-precedence_parser">Operator-Precedence
+Parsing</a>.
+This parsing technique uses the precedence of binary operators to guide
+recursion. To start with, we need a table of precedences:</p>

+</div>
+<p>For the basic form of Kaleidoscope, we will only support 4 binary
+operators (this can obviously be extended by you, our brave and intrepid
+reader). The <tt class="docutils literal"><span class="pre">GetTokPrecedence</span></tt> function returns the precedence for
+the current token, or -1 if the token is not a binary operator. Having a
+map makes it easy to add new operators and makes it clear that the
+algorithm doesn’t depend on the specific operators involved, but it
+would be easy enough to eliminate the map and do the comparisons in the
+<tt class="docutils literal"><span class="pre">GetTokPrecedence</span></tt> function. (Or just use a fixed-size array).</p>
+<p>With the helper above defined, we can now start parsing binary
+expressions. The basic idea of operator precedence parsing is to break
+down an expression with potentially ambiguous binary operators into
+pieces. Consider ,for example, the expression “a+b+(c+d)*e*f+g”.
+Operator precedence parsing considers this as a stream of primary
+expressions separated by binary operators. As such, it will first parse
+the leading primary expression “a”, then it will see the pairs [+, b]
+[+, (c+d)] [*, e] [*, f] and [+, g]. Note that because parentheses are
+primary expressions, the binary expression parser doesn’t need to worry
+about nested subexpressions like (c+d) at all.</p>
+<p>To start, an expression is a primary expression potentially followed by
+a sequence of [binop,primaryexpr] pairs:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// expression</span>
+<span class="c1">/// ::= primary binoprhs</span>

+</pre></div>
+</div>
+<p><tt class="docutils literal"><span class="pre">ParseBinOpRHS</span></tt> is the function that parses the sequence of pairs for
+us. It takes a precedence and a pointer to an expression for the part
+that has been parsed so far. Note that “x” is a perfectly valid
+expression: As such, “binoprhs” is allowed to be empty, in which case it
+returns the expression that is passed into it. In our example above, the
+code passes the expression for “a” into <tt class="docutils literal"><span class="pre">ParseBinOpRHS</span></tt> and the
+current token is “+”.</p>
+<p>The precedence value passed into <tt class="docutils literal"><span class="pre">ParseBinOpRHS</span></tt> indicates the
+<em>minimal operator precedence</em> that the function is allowed to eat. For
+example, if the current pair stream is [+, x] and <tt class="docutils literal"><span class="pre">ParseBinOpRHS</span></tt> is
+passed in a precedence of 40, it will not consume any tokens (because
+the precedence of ‘+’ is only 20). With this in mind, <tt class="docutils literal"><span class="pre">ParseBinOpRHS</span></tt>
+starts with:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// binoprhs</span>

+</pre></div>
+</div>
+<p>This code gets the precedence of the current token and checks to see if
+if is too low. Because we defined invalid tokens to have a precedence of
+-1, this check implicitly knows that the pair-stream ends when the token
+stream runs out of binary operators. If this check succeeds, we know
+that the token is a binary operator and that it will be included in this
+expression:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">// Okay, we know this is a binop.</span>
+<span class="kt">int</span> <span class="n">BinOp</span> <span class="o">=</span> <span class="n">CurTok</span><span class="p">;</span>

+</pre></div>
+</div>
+<p>As such, this code eats (and remembers) the binary operator and then
+parses the primary expression that follows. This builds up the whole
+pair, the first of which is [+, b] for the running example.</p>
+<p>Now that we parsed the left-hand side of an expression and one pair of
+the RHS sequence, we have to decide which way the expression associates.
+In particular, we could have “(a+b) binop unparsed” or “a + (b binop
+unparsed)”. To determine this, we look ahead at “binop” to determine its
+precedence and compare it to BinOp’s precedence (which is ‘+’ in this
+case):</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">// If BinOp binds less tightly with RHS than the operator after RHS, let</span>

+</pre></div>
+</div>
+<p>If the precedence of the binop to the right of “RHS” is lower or equal
+to the precedence of our current operator, then we know that the
+parentheses associate as “(a+b) binop ...”. In our example, the current
+operator is “+” and the next operator is “+”, we know that they have the
+same precedence. In this case we’ll create the AST node for “a+b”, and
+then continue parsing:</p>
+<div class="highlight-c++"><div class="highlight"><pre> <span class="p">...</span> <span class="k">if</span> <span class="n">body</span> <span class="n">omitted</span> <span class="p">...</span>

+ <span class="p">}</span> <span class="c1">// loop around to the top of the while loop.</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>In our example above, this will turn “a+b+” into “(a+b)” and execute the
+next iteration of the loop, with “+” as the current token. The code
+above will eat, remember, and parse “(c+d)” as the primary expression,
+which makes the current pair equal to [+, (c+d)]. It will then evaluate
+the ‘if’ conditional above with “*” as the binop to the right of the
+primary. In this case, the precedence of “*” is higher than the
+precedence of “+” so the if condition will be entered.</p>
+<p>The critical question left here is “how can the if condition parse the
+right hand side in full”? In particular, to build the AST correctly for
+our example, it needs to get all of “(c+d)*e*f” as the RHS expression
+variable. The code to do this is surprisingly simple (code from the
+above two blocks duplicated for context):</p>
+<div class="highlight-c++"><div class="highlight"><pre> <span class="c1">// If BinOp binds less tightly with RHS than the operator after RHS, let</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>At this point, we know that the binary operator to the RHS of our
+primary has higher precedence than the binop we are currently parsing.
+As such, we know that any sequence of pairs whose operators are all
+higher precedence than “+” should be parsed together and returned as
+“RHS”. To do this, we recursively invoke the <tt class="docutils literal"><span class="pre">ParseBinOpRHS</span></tt> function
+specifying “TokPrec+1” as the minimum precedence required for it to
+continue. In our example above, this will cause it to return the AST
+node for “(c+d)*e*f” as RHS, which is then set as the RHS of the ‘+’
+expression.</p>
+<p>Finally, on the next iteration of the while loop, the “+g” piece is
+parsed and added to the AST. With this little bit of code (14
+non-trivial lines), we correctly handle fully general binary expression
+parsing in a very elegant way. This was a whirlwind tour of this code,
+and it is somewhat subtle. I recommend running through it with a few
+tough examples to see how it works.</p>
+<p>This wraps up handling of expressions. At this point, we can point the
+parser at an arbitrary token stream and build an expression from it,
+stopping at the first token that is not part of the expression. Next up
+we need to handle function definitions, etc.</p>

+<p>The most interesting part of this is that we ignore top-level
+semicolons. Why is this, you ask? The basic reason is that if you type
+“4 + 5” at the command line, the parser doesn’t know whether that is the
+end of what you will type or not. For example, on the next line you
+could type “def foo...” in which case 4+5 is the end of a top-level
+expression. Alternatively you could type “* 6”, which would continue
+the expression. Having top-level semicolons allows you to type “4+5;”,
+and the parser will know you are done.</p>

+<p>With just under 400 lines of commented code (240 lines of non-comment,
+non-blank code), we fully defined our minimal language, including a
+lexer, parser, and AST builder. With this done, the executable will
+validate Kaleidoscope code and tell us if it is grammatically invalid.
+For example, here is a sample interaction:</p>
+<div class="highlight-bash"><pre>$ ./a.out
+ready> def foo(x y) x+foo(y, 4.0);
+Parsed a function definition.
+ready> def foo(x y) x+y y;
+Parsed a function definition.
+Parsed a top-level expr
+ready> def foo(x y) x+y );
+Parsed a function definition.
+Error: unknown token when expecting an expression
+ready> extern sin(a);
+ready> Parsed an extern
+ready> ^D
+$</pre>
+</div>
+<p>There is a lot of room for extension here. You can define new AST nodes,
+extend the language in many ways, etc. In the <a class="reference external" href="LangImpl3.html">next
+installment</a>, we will describe how to generate LLVM
+Intermediate Representation (IR) from the AST.</p>

+<p>Welcome to Chapter 3 of the “<a class="reference external" href="index.html">Implementing a language with
+LLVM</a>” tutorial. This chapter shows you how to transform
+the <a class="reference external" href="LangImpl2.html">Abstract Syntax Tree</a>, built in Chapter 2, into
+LLVM IR. This will teach you a little bit about how LLVM does things, as
+well as demonstrate how easy it is to use. It’s much more work to build
+a lexer and parser than it is to generate LLVM IR code. :)</p>
+<p><strong>Please note</strong>: the code in this chapter and later require LLVM 2.2 or
+later. LLVM 2.1 and before will not work with it. Also note that you
+need to use a version of this tutorial that matches your LLVM release:
+If you are using an official LLVM release, use the version of the
+documentation included with your release or on the <a class="reference external" href="http://llvm.org/releases/">llvm.org releases

+<h2><a class="toc-backref" href="#id2">3.2. Code Generation Setup</a><a class="headerlink" href="#code-generation-setup" title="Permalink to this headline">¶</a></h2>
+<p>In order to generate LLVM IR, we want some simple setup to get started.
+First we define virtual code generation (codegen) methods in each AST
+class:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// ExprAST - Base class for all expression nodes.</span>
+<span class="k">class</span> <span class="nc">ExprAST</span> <span class="p">{</span>
+<span class="nl">public:</span>
+ <span class="k">virtual</span> <span class="o">~</span><span class="n">ExprAST</span><span class="p">()</span> <span class="p">{}</span>
+ <span class="k">virtual</span> <span class="n">Value</span> <span class="o">*</span><span class="n">Codegen</span><span class="p">()</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span>
+<span class="p">};</span>
+
+<span class="c1">/// NumberExprAST - Expression class for numeric literals like "1.0".</span>
+<span class="k">class</span> <span class="nc">NumberExprAST</span> <span class="o">:</span> <span class="k">public</span> <span class="n">ExprAST</span> <span class="p">{</span>
+ <span class="kt">double</span> <span class="n">Val</span><span class="p">;</span>
+<span class="nl">public:</span>
+ <span class="n">NumberExprAST</span><span class="p">(</span><span class="kt">double</span> <span class="n">val</span><span class="p">)</span> <span class="o">:</span> <span class="n">Val</span><span class="p">(</span><span class="n">val</span><span class="p">)</span> <span class="p">{}</span>
+ <span class="k">virtual</span> <span class="n">Value</span> <span class="o">*</span><span class="n">Codegen</span><span class="p">();</span>
+<span class="p">};</span>
+<span class="p">...</span>
+</pre></div>
+</div>
+<p>The Codegen() method says to emit IR for that AST node along with all
+the things it depends on, and they all return an LLVM Value object.
+“Value” is the class used to represent a “<a class="reference external" href="http://en.wikipedia.org/wiki/Static_single_assignment_form">Static Single Assignment
+(SSA)</a>
+register” or “SSA value” in LLVM. The most distinct aspect of SSA values
+is that their value is computed as the related instruction executes, and
+it does not get a new value until (and if) the instruction re-executes.
+In other words, there is no way to “change” an SSA value. For more
+information, please read up on <a class="reference external" href="http://en.wikipedia.org/wiki/Static_single_assignment_form">Static Single
+Assignment</a>
+- the concepts are really quite natural once you grok them.</p>
+<p>Note that instead of adding virtual methods to the ExprAST class
+hierarchy, it could also make sense to use a <a class="reference external" href="http://en.wikipedia.org/wiki/Visitor_pattern">visitor
+pattern</a> or some other
+way to model this. Again, this tutorial won’t dwell on good software
+engineering practices: for our purposes, adding a virtual method is
+simplest.</p>
+<p>The second thing we want is an “Error” method like we used for the
+parser, which will be used to report errors found during code generation
+(for example, use of an undeclared parameter):</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="n">Value</span> <span class="o">*</span><span class="nf">ErrorV</span><span class="p">(</span><span class="k">const</span> <span class="kt">char</span> <span class="o">*</span><span class="n">Str</span><span class="p">)</span> <span class="p">{</span> <span class="n">Error</span><span class="p">(</span><span class="n">Str</span><span class="p">);</span> <span class="k">return</span> <span class="mi">0</span><span class="p">;</span> <span class="p">}</span>

+</pre></div>
+</div>
+<p>The static variables will be used during code generation. <tt class="docutils literal"><span class="pre">TheModule</span></tt>
+is the LLVM construct that contains all of the functions and global
+variables in a chunk of code. In many ways, it is the top-level
+structure that the LLVM IR uses to contain code.</p>
+<p>The <tt class="docutils literal"><span class="pre">Builder</span></tt> object is a helper object that makes it easy to generate
+LLVM instructions. Instances of the
+<tt class="docutils literal"><span class="pre">`IRBuilder</span></tt> <<a class="reference external" href="http://llvm.org/doxygen/IRBuilder_8h-source.html">http://llvm.org/doxygen/IRBuilder_8h-source.html</a>>`_
+class template keep track of the current place to insert instructions
+and has methods to create new instructions.</p>
+<p>The <tt class="docutils literal"><span class="pre">NamedValues</span></tt> map keeps track of which values are defined in the
+current scope and what their LLVM representation is. (In other words, it
+is a symbol table for the code). In this form of Kaleidoscope, the only
+things that can be referenced are function parameters. As such, function
+parameters will be in this map when generating code for their function
+body.</p>
+<p>With these basics in place, we can start talking about how to generate
+code for each expression. Note that this assumes that the <tt class="docutils literal"><span class="pre">Builder</span></tt>
+has been set up to generate code <em>into</em> something. For now, we’ll assume
+that this has already been done, and we’ll just use it to emit code.</p>

+<div class="section" id="expression-code-generation">
+<h2><a class="toc-backref" href="#id3">3.3. Expression Code Generation</a><a class="headerlink" href="#expression-code-generation" title="Permalink to this headline">¶</a></h2>
+<p>Generating LLVM code for expression nodes is very straightforward: less
+than 45 lines of commented code for all four of our expression nodes.
+First we’ll do numeric literals:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="n">Value</span> <span class="o">*</span><span class="n">NumberExprAST</span><span class="o">::</span><span class="n">Codegen</span><span class="p">()</span> <span class="p">{</span>
+ <span class="k">return</span> <span class="n">ConstantFP</span><span class="o">::</span><span class="n">get</span><span class="p">(</span><span class="n">getGlobalContext</span><span class="p">(),</span> <span class="n">APFloat</span><span class="p">(</span><span class="n">Val</span><span class="p">));</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>In the LLVM IR, numeric constants are represented with the
+<tt class="docutils literal"><span class="pre">ConstantFP</span></tt> class, which holds the numeric value in an <tt class="docutils literal"><span class="pre">APFloat</span></tt>
+internally (<tt class="docutils literal"><span class="pre">APFloat</span></tt> has the capability of holding floating point
+constants of Arbitrary Precision). This code basically just creates
+and returns a <tt class="docutils literal"><span class="pre">ConstantFP</span></tt>. Note that in the LLVM IR that constants
+are all uniqued together and shared. For this reason, the API uses the
+“foo::get(...)” idiom instead of “new foo(..)” or “foo::Create(..)”.</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="n">Value</span> <span class="o">*</span><span class="n">VariableExprAST</span><span class="o">::</span><span class="n">Codegen</span><span class="p">()</span> <span class="p">{</span>
+ <span class="c1">// Look this variable up in the function.</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>References to variables are also quite simple using LLVM. In the simple
+version of Kaleidoscope, we assume that the variable has already been
+emitted somewhere and its value is available. In practice, the only
+values that can be in the <tt class="docutils literal"><span class="pre">NamedValues</span></tt> map are function arguments.
+This code simply checks to see that the specified name is in the map (if
+not, an unknown variable is being referenced) and returns the value for
+it. In future chapters, we’ll add support for <a class="reference external" href="LangImpl5.html#for">loop induction
+variables</a> in the symbol table, and for <a class="reference external" href="LangImpl7.html#localvars">local
+variables</a>.</p>

+<p>Binary operators start to get more interesting. The basic idea here is
+that we recursively emit code for the left-hand side of the expression,
+then the right-hand side, then we compute the result of the binary
+expression. In this code, we do a simple switch on the opcode to create
+the right LLVM instruction.</p>
+<p>In the example above, the LLVM builder class is starting to show its
+value. IRBuilder knows where to insert the newly created instruction,
+all you have to do is specify what instruction to create (e.g. with
+<tt class="docutils literal"><span class="pre">CreateFAdd</span></tt>), which operands to use (<tt class="docutils literal"><span class="pre">L</span></tt> and <tt class="docutils literal"><span class="pre">R</span></tt> here) and
+optionally provide a name for the generated instruction.</p>
+<p>One nice thing about LLVM is that the name is just a hint. For instance,
+if the code above emits multiple “addtmp” variables, LLVM will
+automatically provide each one with an increasing, unique numeric
+suffix. Local value names for instructions are purely optional, but it
+makes it much easier to read the IR dumps.</p>
+<p><a class="reference external" href="../LangRef.html#instref">LLVM instructions</a> are constrained by strict
+rules: for example, the Left and Right operators of an <a class="reference external" href="../LangRef.html#i_add">add
+instruction</a> must have the same type, and the
+result type of the add must match the operand types. Because all values
+in Kaleidoscope are doubles, this makes for very simple code for add,
+sub and mul.</p>
+<p>On the other hand, LLVM specifies that the <a class="reference external" href="../LangRef.html#i_fcmp">fcmp
+instruction</a> always returns an ‘i1’ value (a
+one bit integer). The problem with this is that Kaleidoscope wants the
+value to be a 0.0 or 1.0 value. In order to get these semantics, we
+combine the fcmp instruction with a <a class="reference external" href="../LangRef.html#i_uitofp">uitofp
+instruction</a>. This instruction converts its
+input integer into a floating point value by treating the input as an
+unsigned value. In contrast, if we used the <a class="reference external" href="../LangRef.html#i_sitofp">sitofp
+instruction</a>, the Kaleidoscope ‘<’ operator
+would return 0.0 and -1.0, depending on the input value.</p>

+<p>Code generation for function calls is quite straightforward with LLVM.
+The code above initially does a function name lookup in the LLVM
+Module’s symbol table. Recall that the LLVM Module is the container that
+holds all of the functions we are JIT’ing. By giving each function the
+same name as what the user specifies, we can use the LLVM symbol table
+to resolve function names for us.</p>
+<p>Once we have the function to call, we recursively codegen each argument
+that is to be passed in, and create an LLVM <a class="reference external" href="../LangRef.html#i_call">call
+instruction</a>. Note that LLVM uses the native C
+calling conventions by default, allowing these calls to also call into
+standard library functions like “sin” and “cos”, with no additional
+effort.</p>
+<p>This wraps up our handling of the four basic expressions that we have so
+far in Kaleidoscope. Feel free to go in and add some more. For example,
+by browsing the <a class="reference external" href="../LangRef.html">LLVM language reference</a> you’ll find
+several other interesting instructions that are really easy to plug into
+our basic framework.</p>

+<p>This code packs a lot of power into a few lines. Note first that this
+function returns a “Function*” instead of a “Value*”. Because a
+“prototype” really talks about the external interface for a function
+(not the value computed by an expression), it makes sense for it to
+return the LLVM Function it corresponds to when codegen’d.</p>
+<p>The call to <tt class="docutils literal"><span class="pre">FunctionType::get</span></tt> creates the <tt class="docutils literal"><span class="pre">FunctionType</span></tt> that
+should be used for a given Prototype. Since all function arguments in
+Kaleidoscope are of type double, the first line creates a vector of “N”
+LLVM double types. It then uses the <tt class="docutils literal"><span class="pre">Functiontype::get</span></tt> method to
+create a function type that takes “N” doubles as arguments, returns one
+double as a result, and that is not vararg (the false parameter
+indicates this). Note that Types in LLVM are uniqued just like Constants
+are, so you don’t “new” a type, you “get” it.</p>
+<p>The final line above actually creates the function that the prototype
+will correspond to. This indicates the type, linkage and name to use, as
+well as which module to insert into. “<a class="reference external" href="../LangRef.html#linkage">external
+linkage</a>” means that the function may be
+defined outside the current module and/or that it is callable by
+functions outside the module. The Name passed in is the name the user
+specified: since “<tt class="docutils literal"><span class="pre">TheModule</span></tt>” is specified, this name is registered
+in “<tt class="docutils literal"><span class="pre">TheModule</span></tt>“s symbol table, which is used by the function call
+code above.</p>

+<p>The Module symbol table works just like the Function symbol table when
+it comes to name conflicts: if a new function is created with a name
+that was previously added to the symbol table, the new function will get
+implicitly renamed when added to the Module. The code above exploits
+this fact to determine if there was a previous definition of this
+function.</p>
+<p>In Kaleidoscope, I choose to allow redefinitions of functions in two
+cases: first, we want to allow ‘extern’ing a function more than once, as
+long as the prototypes for the externs match (since all arguments have
+the same type, we just have to check that the number of arguments
+match). Second, we want to allow ‘extern’ing a function and then
+defining a body for it. This is useful when defining mutually recursive
+functions.</p>
+<p>In order to implement this, the code above first checks to see if there
+is a collision on the name of the function. If so, it deletes the
+function we just created (by calling <tt class="docutils literal"><span class="pre">eraseFromParent</span></tt>) and then
+calling <tt class="docutils literal"><span class="pre">getFunction</span></tt> to get the existing function with the specified
+name. Note that many APIs in LLVM have “erase” forms and “remove” forms.
+The “remove” form unlinks the object from its parent (e.g. a Function
+from a Module) and returns it. The “erase” form unlinks the object and
+then deletes it.</p>

+<p>In order to verify the logic above, we first check to see if the

+is a forward declaration. Since we don’t allow anything after a full
+definition of the function, the code rejects this case. If the previous
+reference to a function was an ‘extern’, we simply verify that the
+number of arguments for that definition and this one match up. If not,

+Once the function is built, we call <tt class="docutils literal"><span class="pre">verifyFunction</span></tt>, which is
+provided by LLVM. This function does a variety of consistency checks on

+<p>The only piece left here is handling of the error case. For simplicity,
+we handle this by merely deleting the function we produced with the

+<p>This code does have a bug, though. Since the <tt class="docutils literal"><span class="pre">PrototypeAST::Codegen</span></tt>
+can return a previously defined forward declaration, our code can
+actually delete a forward declaration. There are a number of ways to fix
+this bug, see what you can come up with! Here is a testcase:</p>
+<div class="highlight-python"><pre>extern foo(a b); # ok, defines foo.

+<p>For now, code generation to LLVM doesn’t really get us much, except that
+we can look at the pretty IR calls. The sample code inserts calls to
+Codegen into the “<tt class="docutils literal"><span class="pre">HandleDefinition</span></tt>”, “<tt class="docutils literal"><span class="pre">HandleExtern</span></tt>” etc
+functions, and then dumps out the LLVM IR. This gives a nice way to look
+at the LLVM IR for simple functions. For example:</p>
+<div class="highlight-python"><pre>ready> 4+5;
+Read top-level expression:
+define double @0() {
+entry:
+ ret double 9.000000e+00
+}</pre>
+</div>
+<p>Note how the parser turns the top-level expression into anonymous
+functions for us. This will be handy when we add <a class="reference external" href="LangImpl4.html#jit">JIT
+support</a> in the next chapter. Also note that the
+code is very literally transcribed, no optimizations are being performed
+except simple constant folding done by IRBuilder. We will <a class="reference external" href="LangImpl4.html#trivialconstfold">add
+optimizations</a> explicitly in the next
+chapter.</p>
+<div class="highlight-python"><pre>ready> def foo(a b) a*a + 2*a*b + b*b;

+ %addtmp = fadd double %multmp, %multmp2
+ %multmp3 = fmul double %b, %b
+ %addtmp4 = fadd double %addtmp, %multmp3
+ ret double %addtmp4
+}</pre>
+</div>
+<p>This shows some simple arithmetic. Notice the striking similarity to the
+LLVM builder calls that we use to create the instructions.</p>
+<div class="highlight-python"><pre>ready> def bar(a) foo(a, 4.0) + bar(31337);

+<p>This shows some function calls. Note that this function will take a long

+<h2><a class="toc-backref" href="#id1">4.1. Chapter 4 Introduction</a><a class="headerlink" href="#chapter-4-introduction" title="Permalink to this headline">¶</a></h2>
+<p>Welcome to Chapter 4 of the “<a class="reference external" href="index.html">Implementing a language with
+LLVM</a>” tutorial. Chapters 1-3 described the implementation
+of a simple language and added support for generating LLVM IR. This
+chapter describes two new techniques: adding optimizer support to your
+language, and adding JIT compiler support. These additions will
+demonstrate how to get nice, efficient code for the Kaleidoscope
+language.</p>
+</div>
+<div class="section" id="trivial-constant-folding">
+<h2><a class="toc-backref" href="#id2">4.2. Trivial Constant Folding</a><a class="headerlink" href="#trivial-constant-folding" title="Permalink to this headline">¶</a></h2>
+<p>Our demonstration for Chapter 3 is elegant and easy to extend.
+Unfortunately, it does not produce wonderful code. The IRBuilder,
+however, does give us obvious optimizations when compiling simple code:</p>
+<div class="highlight-python"><pre>ready> def test(x) 1+2+x;
+Read function definition:
+define double @test(double %x) {
+entry:
+ %addtmp = fadd double 3.000000e+00, %x
+ ret double %addtmp
+}</pre>
+</div>
+<p>This code is not a literal transcription of the AST built by parsing the
+input. That would be:</p>
+<div class="highlight-python"><pre>ready> def test(x) 1+2+x;
+Read function definition:
+define double @test(double %x) {
+entry:
+ %addtmp = fadd double 2.000000e+00, 1.000000e+00
+ %addtmp1 = fadd double %addtmp, %x
+ ret double %addtmp1
+}</pre>
+</div>
+<p>Constant folding, as seen above, in particular, is a very common and
+very important optimization: so much so that many language implementors
+implement constant folding support in their AST representation.</p>
+<p>With LLVM, you don’t need this support in the AST. Since all calls to
+build LLVM IR go through the LLVM IR builder, the builder itself checked
+to see if there was a constant folding opportunity when you call it. If
+so, it just does the constant fold and return the constant instead of
+creating an instruction.</p>
+<p>Well, that was easy :). In practice, we recommend always using
+<tt class="docutils literal"><span class="pre">IRBuilder</span></tt> when generating code like this. It has no “syntactic
+overhead” for its use (you don’t have to uglify your compiler with
+constant checks everywhere) and it can dramatically reduce the amount of
+LLVM IR that is generated in some cases (particular for languages with a
+macro preprocessor or that use a lot of constants).</p>
+<p>On the other hand, the <tt class="docutils literal"><span class="pre">IRBuilder</span></tt> is limited by the fact that it does
+all of its analysis inline with the code as it is built. If you take a
+slightly more complex example:</p>
+<div class="highlight-python"><pre>ready> def test(x) (1+2+x)*(x+(1+2));
+ready> Read function definition:
+define double @test(double %x) {
+entry:
+ %addtmp = fadd double 3.000000e+00, %x
+ %addtmp1 = fadd double %x, 3.000000e+00
+ %multmp = fmul double %addtmp, %addtmp1
+ ret double %multmp
+}</pre>
+</div>
+<p>In this case, the LHS and RHS of the multiplication are the same value.
+We’d really like to see this generate “<tt class="docutils literal"><span class="pre">tmp</span> <span class="pre">=</span> <span class="pre">x+3;</span> <span class="pre">result</span> <span class="pre">=</span> <span class="pre">tmp*tmp;</span></tt>”
+instead of computing “<tt class="docutils literal"><span class="pre">x+3</span></tt>” twice.</p>
+<p>Unfortunately, no amount of local analysis will be able to detect and
+correct this. This requires two transformations: reassociation of
+expressions (to make the add’s lexically identical) and Common
+Subexpression Elimination (CSE) to delete the redundant add instruction.
+Fortunately, LLVM provides a broad range of optimizations that you can
+use, in the form of “passes”.</p>
+</div>
+<div class="section" id="llvm-optimization-passes">
+<h2><a class="toc-backref" href="#id3">4.3. LLVM Optimization Passes</a><a class="headerlink" href="#llvm-optimization-passes" title="Permalink to this headline">¶</a></h2>
+<p>LLVM provides many optimization passes, which do many different sorts of
+things and have different tradeoffs. Unlike other systems, LLVM doesn’t
+hold to the mistaken notion that one set of optimizations is right for
+all languages and for all situations. LLVM allows a compiler implementor
+to make complete decisions about what optimizations to use, in which
+order, and in what situation.</p>
+<p>As a concrete example, LLVM supports both “whole module” passes, which
+look across as large of body of code as they can (often a whole file,
+but if run at link time, this can be a substantial portion of the whole
+program). It also supports and includes “per-function” passes which just
+operate on a single function at a time, without looking at other
+functions. For more information on passes and how they are run, see the
+<a class="reference external" href="../WritingAnLLVMPass.html">How to Write a Pass</a> document and the
+<a class="reference external" href="../Passes.html">List of LLVM Passes</a>.</p>
+<p>For Kaleidoscope, we are currently generating functions on the fly, one
+at a time, as the user types them in. We aren’t shooting for the
+ultimate optimization experience in this setting, but we also want to
+catch the easy and quick stuff where possible. As such, we will choose
+to run a few per-function optimizations as the user types the function
+in. If we wanted to make a “static Kaleidoscope compiler”, we would use
+exactly the code we have now, except that we would defer running the
+optimizer until the entire file has been parsed.</p>
+<p>In order to get per-function optimizations going, we need to set up a
+<a class="reference external" href="../WritingAnLLVMPass.html#passmanager">FunctionPassManager</a> to hold

+that, we can add a set of optimizations to run. The code looks like

+</div>
+<p>This code defines a <tt class="docutils literal"><span class="pre">FunctionPassManager</span></tt>, “<tt class="docutils literal"><span class="pre">OurFPM</span></tt>”. It requires a
+pointer to the <tt class="docutils literal"><span class="pre">Module</span></tt> to construct itself. Once it is set up, we use
+a series of “add” calls to add a bunch of LLVM passes. The first pass is
+basically boilerplate, it adds a pass so that later optimizations know
+how the data structures in the program are laid out. The
+“<tt class="docutils literal"><span class="pre">TheExecutionEngine</span></tt>” variable is related to the JIT, which we will
+get to in the next section.</p>
+<p>In this case, we choose to add 4 optimization passes. The passes we
+chose here are a pretty standard set of “cleanup” optimizations that are
+useful for a wide variety of code. I won’t delve into what they do but,
+believe me, they are a good starting place :).</p>
+<p>Once the PassManager is set up, we need to make use of it. We do this by
+running it after our newly created function is constructed (in
+<tt class="docutils literal"><span class="pre">FunctionAST::Codegen</span></tt>), but before it is returned to the client:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="k">if</span> <span class="p">(</span><span class="n">Value</span> <span class="o">*</span><span class="n">RetVal</span> <span class="o">=</span> <span class="n">Body</span><span class="o">-></span><span class="n">Codegen</span><span class="p">())</span> <span class="p">{</span>

+</pre></div>
+</div>
+<p>As you can see, this is pretty straightforward. The
+<tt class="docutils literal"><span class="pre">FunctionPassManager</span></tt> optimizes and updates the LLVM Function* in
+place, improving (hopefully) its body. With this in place, we can try
+our test above again:</p>
+<div class="highlight-python"><pre>ready> def test(x) (1+2+x)*(x+(1+2));
+ready> Read function definition:
+define double @test(double %x) {
+entry:
+ %addtmp = fadd double %x, 3.000000e+00
+ %multmp = fmul double %addtmp, %addtmp
+ ret double %multmp
+}</pre>
+</div>
+<p>As expected, we now get our nicely optimized code, saving a floating
+point add instruction from every execution of this function.</p>
+<p>LLVM provides a wide variety of optimizations that can be used in
+certain circumstances. Some <a class="reference external" href="../Passes.html">documentation about the various
+passes</a> is available, but it isn’t very complete.
+Another good source of ideas can come from looking at the passes that
+<tt class="docutils literal"><span class="pre">Clang</span></tt> runs to get started. The “<tt class="docutils literal"><span class="pre">opt</span></tt>” tool allows you to
+experiment with passes from the command line, so you can see if they do
+anything.</p>
+<p>Now that we have reasonable code coming out of our front-end, lets talk
+about executing it!</p>
+</div>
+<div class="section" id="adding-a-jit-compiler">
+<h2><a class="toc-backref" href="#id4">4.4. Adding a JIT Compiler</a><a class="headerlink" href="#adding-a-jit-compiler" title="Permalink to this headline">¶</a></h2>
+<p>Code that is available in LLVM IR can have a wide variety of tools
+applied to it. For example, you can run optimizations on it (as we did
+above), you can dump it out in textual or binary forms, you can compile
+the code to an assembly file (.s) for some target, or you can JIT
+compile it. The nice thing about the LLVM IR representation is that it
+is the “common currency” between many different parts of the compiler.</p>
+<p>In this section, we’ll add JIT compiler support to our interpreter. The
+basic idea that we want for Kaleidoscope is to have the user enter
+function bodies as they do now, but immediately evaluate the top-level
+expressions they type in. For example, if they type in “1 + 2;”, we
+should evaluate and print out 3. If they define a function, they should
+be able to call it from the command line.</p>
+<p>In order to do this, we first declare and initialize the JIT. This is
+done by adding a global variable and a call in <tt class="docutils literal"><span class="pre">main</span></tt>:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="k">static</span> <span class="n">ExecutionEngine</span> <span class="o">*</span><span class="n">TheExecutionEngine</span><span class="p">;</span>
+<span class="p">...</span>
+<span class="kt">int</span> <span class="n">main</span><span class="p">()</span> <span class="p">{</span>
+ <span class="p">..</span>
+ <span class="c1">// Create the JIT. This takes ownership of the module.</span>
+ <span class="n">TheExecutionEngine</span> <span class="o">=</span> <span class="n">EngineBuilder</span><span class="p">(</span><span class="n">TheModule</span><span class="p">).</span><span class="n">create</span><span class="p">();</span>
+ <span class="p">..</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>This creates an abstract “Execution Engine” which can be either a JIT
+compiler or the LLVM interpreter. LLVM will automatically pick a JIT
+compiler for you if one is available for your platform, otherwise it
+will fall back to the interpreter.</p>
+<p>Once the <tt class="docutils literal"><span class="pre">ExecutionEngine</span></tt> is created, the JIT is ready to be used.
+There are a variety of APIs that are useful, but the simplest one is the
+“<tt class="docutils literal"><span class="pre">getPointerToFunction(F)</span></tt>” method. This method JIT compiles the
+specified LLVM Function and returns a function pointer to the generated
+machine code. In our case, this means that we can change the code that
+parses a top-level expression to look like this:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="k">static</span> <span class="kt">void</span> <span class="nf">HandleTopLevelExpression</span><span class="p">()</span> <span class="p">{</span>

+ <span class="p">}</span>
+</pre></div>
+</div>
+<p>Recall that we compile top-level expressions into a self-contained LLVM
+function that takes no arguments and returns the computed double.
+Because the LLVM JIT compiler matches the native platform ABI, this
+means that you can just cast the result pointer to a function pointer of
+that type and call it directly. This means, there is no difference
+between JIT compiled code and native machine code that is statically
+linked into your application.</p>
+<p>With just these two changes, lets see how Kaleidoscope works now!</p>
+<div class="highlight-python"><pre>ready> 4+5;
+Read top-level expression:
+define double @0() {
+entry:
+ ret double 9.000000e+00
+}
+
+Evaluated to 9.000000</pre>
+</div>
+<p>Well this looks like it is basically working. The dump of the function
+shows the “no argument function that always returns double” that we
+synthesize for each top-level expression that is typed in. This
+demonstrates very basic functionality, but can we do more?</p>
+<div class="highlight-python"><pre>ready> def testfunc(x y) x + y*2;
+Read function definition:
+define double @testfunc(double %x, double %y) {
+entry:
+ %multmp = fmul double %y, 2.000000e+00
+ %addtmp = fadd double %multmp, %x
+ ret double %addtmp
+}
+
+ready> testfunc(4, 10);
+Read top-level expression:
+define double @1() {
+entry:
+ %calltmp = call double @testfunc(double 4.000000e+00, double 1.000000e+01)
+ ret double %calltmp
+}
+
+Evaluated to 24.000000</pre>
+</div>
+<p>This illustrates that we can now call user code, but there is something
+a bit subtle going on here. Note that we only invoke the JIT on the
+anonymous functions that <em>call testfunc</em>, but we never invoked it on
+<em>testfunc</em> itself. What actually happened here is that the JIT scanned
+for all non-JIT’d functions transitively called from the anonymous
+function and compiled all of them before returning from
+<tt class="docutils literal"><span class="pre">getPointerToFunction()</span></tt>.</p>
+<p>The JIT provides a number of other more advanced interfaces for things
+like freeing allocated machine code, rejit’ing functions to update them,
+etc. However, even with this simple code, we get some surprisingly
+powerful capabilities - check this out (I removed the dump of the
+anonymous functions, you should get the idea by now :) :</p>
+<div class="highlight-python"><pre>ready> extern sin(x);
+Read extern:
+declare double @sin(double)
+
+ready> extern cos(x);
+Read extern:
+declare double @cos(double)
+
+ready> sin(1.0);
+Read top-level expression:
+define double @2() {
+entry:
+ ret double 0x3FEAED548F090CEE
+}
+
+Evaluated to 0.841471
+
+ready> def foo(x) sin(x)*sin(x) + cos(x)*cos(x);
+Read function definition:
+define double @foo(double %x) {
+entry:
+ %calltmp = call double @sin(double %x)
+ %multmp = fmul double %calltmp, %calltmp
+ %calltmp2 = call double @cos(double %x)
+ %multmp4 = fmul double %calltmp2, %calltmp2
+ %addtmp = fadd double %multmp, %multmp4
+ ret double %addtmp
+}
+
+ready> foo(4.0);
+Read top-level expression:
+define double @3() {
+entry:
+ %calltmp = call double @foo(double 4.000000e+00)
+ ret double %calltmp
+}
+
+Evaluated to 1.000000</pre>
+</div>
+<p>Whoa, how does the JIT know about sin and cos? The answer is
+surprisingly simple: in this example, the JIT started execution of a
+function and got to a function call. It realized that the function was
+not yet JIT compiled and invoked the standard set of routines to resolve
+the function. In this case, there is no body defined for the function,
+so the JIT ended up calling “<tt class="docutils literal"><span class="pre">dlsym("sin")</span></tt>” on the Kaleidoscope
+process itself. Since “<tt class="docutils literal"><span class="pre">sin</span></tt>” is defined within the JIT’s address
+space, it simply patches up calls in the module to call the libm version
+of <tt class="docutils literal"><span class="pre">sin</span></tt> directly.</p>
+<p>The LLVM JIT provides a number of interfaces (look in the
+<tt class="docutils literal"><span class="pre">ExecutionEngine.h</span></tt> file) for controlling how unknown functions get
+resolved. It allows you to establish explicit mappings between IR
+objects and addresses (useful for LLVM global variables that you want to
+map to static tables, for example), allows you to dynamically decide on
+the fly based on the function name, and even allows you to have the JIT
+compile functions lazily the first time they’re called.</p>
+<p>One interesting application of this is that we can now extend the
+language by writing arbitrary C++ code to implement operations. For
+example, if we add:</p>
+<div class="highlight-c++"><div class="highlight"><pre><span class="c1">/// putchard - putchar that takes a double and returns 0.</span>
+<span class="k">extern</span> <span class="s">"C"</span>
+<span class="kt">double</span> <span class="n">putchard</span><span class="p">(</span><span class="kt">double</span> <span class="n">X</span><span class="p">)</span> <span class="p">{</span>
+ <span class="n">putchar</span><span class="p">((</span><span class="kt">char</span><span class="p">)</span><span class="n">X</span><span class="p">);</span>
+ <span class="k">return</span> <span class="mi">0</span><span class="p">;</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Now we can produce simple output to the console by using things like:
+“<tt class="docutils literal"><span class="pre">extern</span> <span class="pre">putchard(x);</span> <span class="pre">putchard(120);</span></tt>”, which prints a lowercase ‘x’
+on the console (120 is the ASCII code for ‘x’). Similar code could be
+used to implement file I/O, console input, and many other capabilities
+in Kaleidoscope.</p>
+<p>This completes the JIT and optimizer chapter of the Kaleidoscope
+tutorial. At this point, we can compile a non-Turing-complete
+programming language, optimize and JIT compile it in a user-driven way.
+Next up we’ll look into <a class="reference external" href="LangImpl5.html">extending the language with control flow
+constructs</a>, tackling some interesting LLVM IR issues

+<p>Welcome to Chapter 5 of the “<a class="reference external" href="index.html">Implementing a language with
+LLVM</a>” tutorial. Parts 1-4 described the implementation of
+the simple Kaleidoscope language and included support for generating
+LLVM IR, followed by optimizations and a JIT compiler. Unfortunately, as
+presented, Kaleidoscope is mostly useless: it has no control flow other
+than call and return. This means that you can’t have conditional
+branches in the code, significantly limiting its power. In this episode
+of “build that compiler”, we’ll extend Kaleidoscope to have an
+if/then/else expression plus a simple ‘for’ loop.</p>
+</div>

+<h2><a class="toc-backref" href="#id2">5.2. If/Then/Else</a><a class="headerlink" href="#if-then-else" title="Permalink to this headline">¶</a></h2>
+<p>Extending Kaleidoscope to support if/then/else is quite straightforward.
+It basically requires adding support for this “new” concept to the
+lexer, parser, AST, and LLVM code emitter. This example is nice, because
+it shows how easy it is to “grow” a language over time, incrementally
+extending it as new ideas are discovered.</p>
+<p>Before we get going on “how” we add this extension, lets talk about
+“what” we want. The basic idea is that we want to be able to write this
+sort of thing:</p>
+<div class="highlight-python"><pre>def fib(x)
+ if x < 3 then
+ 1
+ else
+ fib(x-1)+fib(x-2);</pre>
+</div>
+<p>In Kaleidoscope, every construct is an expression: there are no
+statements. As such, the if/then/else expression needs to return a value
+like any other. Since we’re using a mostly functional form, we’ll have
+it evaluate its conditional, then return the ‘then’ or ‘else’ value
+based on how the condition was resolved. This is very similar to the C
+”?:” expression.</p>
+<p>The semantics of the if/then/else expression is that it evaluates the
+condition to a boolean equality value: 0.0 is considered to be false and
+everything else is considered to be true. If the condition is true, the
+first subexpression is evaluated and returned, if the condition is
+false, the second subexpression is evaluated and returned. Since
+Kaleidoscope allows side-effects, this behavior is important to nail
+down.</p>
+<p>Now that we know what we “want”, lets break this down into its
+constituent pieces.</p>

+<p>Now that we have it parsing and building the AST, the final piece is
+adding LLVM code generation support. This is the most interesting part
+of the if/then/else example, because this is where it starts to
+introduce new concepts. All of the code above has been thoroughly
+described in previous chapters.</p>
+<p>To motivate the code we want to produce, lets take a look at a simple
+example. Consider:</p>
+<div class="highlight-python"><pre>extern foo();
+extern bar();
+def baz(x) if x then foo() else bar();</pre>
+</div>
+<p>If you disable optimizations, the code you’ll (soon) get from

+</div>
+<p>To visualize the control flow graph, you can use a nifty feature of the
+LLVM ‘<a class="reference external" href="http://llvm.org/cmds/opt.html">opt</a>‘ tool. If you put this LLVM
+IR into “t.ll” and run “<tt class="docutils literal"><span class="pre">llvm-as</span> <span class="pre"><</span> <span class="pre">t.ll</span> <span class="pre">|</span> <span class="pre">opt</span> <span class="pre">-analyze</span> <span class="pre">-view-cfg</span></tt>”, <a class="reference external" href="../ProgrammersManual.html#ViewGraph">a
+window will pop up</a> and you’ll
+see this graph:</p>
+<div class="figure align-center">
+<img alt="Example CFG" src="../_images/LangImpl5-cfg.png" />
+<p class="caption">Example CFG</p>
+</div>
+<p>Another way to get this is to call “<tt class="docutils literal"><span class="pre">F->viewCFG()</span></tt>” or
+“<tt class="docutils literal"><span class="pre">F->viewCFGOnly()</span></tt>” (where F is a “<tt class="docutils literal"><span class="pre">Function*</span></tt>”) either by
+inserting actual calls into the code and recompiling or by calling these
+in the debugger. LLVM has many nice features for visualizing various
+graphs.</p>
+<p>Getting back to the generated code, it is fairly simple: the entry block
+evaluates the conditional expression (“x” in our case here) and compares
+the result to 0.0 with the “<tt class="docutils literal"><span class="pre">fcmp</span> <span class="pre">one</span></tt>” instruction (‘one’ is “Ordered
+and Not Equal”). Based on the result of this expression, the code jumps
+to either the “then” or “else” blocks, which contain the expressions for
+the true/false cases.</p>
+<p>Once the then/else blocks are finished executing, they both branch back
+to the ‘ifcont’ block to execute the code that happens after the
+if/then/else. In this case the only thing left to do is to return to the
+caller of the function. The question then becomes: how does the code
+know which expression to return?</p>
+<p>The answer to this question involves an important SSA operation: the
+<a class="reference external" href="http://en.wikipedia.org/wiki/Static_single_assignment_form">Phi
+operation</a>.
+If you’re not familiar with SSA, <a class="reference external" href="http://en.wikipedia.org/wiki/Static_single_assignment_form">the wikipedia
+article</a>
+is a good introduction and there are various other introductions to it
+available on your favorite search engine. The short version is that
+“execution” of the Phi operation requires “remembering” which block
+control came from. The Phi operation takes on the value corresponding to
+the input control block. In this case, if control comes in from the
+“then” block, it gets the value of “calltmp”. If control comes from the
+“else” block, it gets the value of “calltmp1”.</p>
+<p>At this point, you are probably starting to think “Oh no! This means my
+simple and elegant front-end will have to start generating SSA form in
+order to use LLVM!”. Fortunately, this is not the case, and we strongly
+advise <em>not</em> implementing an SSA construction algorithm in your
+front-end unless there is an amazingly good reason to do so. In
+practice, there are two sorts of values that float around in code
+written for your average imperative programming language that might need
+Phi nodes:</p>
+<ol class="arabic simple">
+<li>Code that involves user variables: <tt class="docutils literal"><span class="pre">x</span> <span class="pre">=</span> <span class="pre">1;</span> <span class="pre">x</span> <span class="pre">=</span> <span class="pre">x</span> <span class="pre">+</span> <span class="pre">1;</span></tt></li>
+<li>Values that are implicit in the structure of your AST, such as the
+Phi node in this case.</li>
+</ol>
+<p>In <a class="reference external" href="LangImpl7.html">Chapter 7</a> of this tutorial (“mutable variables”),
+we’ll talk about #1 in depth. For now, just believe me that you don’t
+need SSA construction to handle this case. For #2, you have the choice
+of using the techniques that we will describe for #1, or you can insert
+Phi nodes directly, if convenient. In this case, it is really really
+easy to generate the Phi node, so we choose to do it directly.</p>

+<p>This code creates the basic blocks that are related to the if/then/else
+statement, and correspond directly to the blocks in the example above.
+The first line gets the current Function object that is being built. It
+gets this by asking the builder for the current BasicBlock, and asking
+that block for its “parent” (the function it is currently embedded
+into).</p>
+<p>Once it has that, it creates three blocks. Note that it passes
+“TheFunction” into the constructor for the “then” block. This causes the
+constructor to automatically insert the new block into the end of the
+specified function. The other two blocks are created, but aren’t yet
+inserted into the function.</p>
+<p>Once the blocks are created, we can emit the conditional branch that
+chooses between them. Note that creating new blocks does not implicitly
+affect the IRBuilder, so it is still inserting into the block that the

+<p>After the conditional branch is inserted, we move the builder to start
+inserting into the “then” block. Strictly speaking, this call moves the
+insertion point to be at the end of the specified block. However, since
+the “then” block is empty, it also starts out by inserting at the
+beginning of the block. :)</p>
+<p>Once the insertion point is set, we recursively codegen the “then”
+expression from the AST. To finish off the “then” block, we create an
+unconditional branch to the merge block. One interesting (and very
+important) aspect of the LLVM IR is that it <a class="reference external" href="../LangRef.html#functionstructure">requires all basic blocks
+to be “terminated”</a> with a <a class="reference external" href="../LangRef.html#terminators">control
+flow instruction</a> such as return or
+branch. This means that all control flow, <em>including fall throughs</em> must
+be made explicit in the LLVM IR. If you violate this rule, the verifier
+will emit an error.</p>
+<p>The final line here is quite subtle, but is very important. The basic
+issue is that when we create the Phi node in the merge block, we need to
+set up the block/value pairs that indicate how the Phi will work.
+Importantly, the Phi node expects to have an entry for each predecessor
+of the block in the CFG. Why then, are we getting the current block when
+we just set it to ThenBB 5 lines above? The problem is that the “Then”
+expression may actually itself change the block that the Builder is
+emitting into if, for example, it contains a nested “if/then/else”
+expression. Because calling Codegen recursively could arbitrarily change
+the notion of the current block, we are required to get an up-to-date
+value for code that will set up the Phi node.</p>

+<p>Code generation for the ‘else’ block is basically identical to codegen
+for the ‘then’ block. The only significant difference is the first line,
+which adds the ‘else’ block to the function. Recall previously that the
+‘else’ block was created, but not added to the function. Now that the
+‘then’ and ‘else’ blocks are emitted, we can finish up with the merge

+<p>The first two lines here are now familiar: the first adds the “merge”
+block to the Function object (it was previously floating, like the else
+block above). The second block changes the insertion point so that newly
+created code will go into the “merge” block. Once that is done, we need
+to create the PHI node and set up the block/value pairs for the PHI.</p>
+<p>Finally, the CodeGen function returns the phi node as the value computed
+by the if/then/else expression. In our example above, this returned
+value will feed into the code for the top-level function, which will
+create the return instruction.</p>
+<p>Overall, we now have the ability to execute conditional code in
+Kaleidoscope. With this extension, Kaleidoscope is a fairly complete
+language that can calculate a wide variety of numeric functions. Next up
+we’ll add another useful expression that is familiar from non-functional
+languages...</p>

+<p>Now that we know how to add basic control flow constructs to the
+language, we have the tools to add more powerful things. Lets add
+something more aggressive, a ‘for’ expression:</p>
+<div class="highlight-python"><pre>extern putchard(char)
+def printstar(n)
+ for i = 1, i < n, 1.0 in
+ putchard(42); # ascii 42 = '*'
+
+# print 100 '*' characters
+printstar(100);</pre>
+</div>
+<p>This expression defines a new variable (“i” in this case) which iterates
+from a starting value, while the condition (“i < n” in this case) is
+true, incrementing by an optional step value (“1.0” in this case). If
+the step value is omitted, it defaults to 1.0. While the loop is true,
+it executes its body expression. Because we don’t have anything better
+to return, we’ll just define the loop as always returning 0.0. In the
+future when we have mutable variables, it will get more useful.</p>
+<p>As before, lets talk about the changes that we need to Kaleidoscope to
+support this.</p>

+</pre></div>
+</div>
+<p>With this out of the way, the next step is to set up the LLVM basic
+block for the start of the loop body. In the case above, the whole loop
+body is one block, but remember that the body code itself could consist
+of multiple blocks (e.g. if it contains an if/then/else or a for/in

+<p>This code is similar to what we saw for if/then/else. Because we will
+need it to create the Phi node, we remember the block that falls through
+into the loop. Once we have that, we create the actual block that starts
+the loop and create an unconditional branch for the fall-through between
+the two blocks.</p>

+</div>
+<p>Now that the “preheader” for the loop is set up, we switch to emitting
+code for the loop body. To begin with, we move the insertion point and
+create the PHI node for the loop induction variable. Since we already
+know the incoming value for the starting value, we add it to the Phi
+node. Note that the Phi will eventually get a second value for the
+backedge, but we can’t set it up yet (because it doesn’t exist!).</p>

+</pre></div>
+</div>
+<p>Now the code starts to get more interesting. Our ‘for’ loop introduces a
+new variable to the symbol table. This means that our symbol table can
+now contain either function arguments or loop variables. To handle this,
+before we codegen the body of the loop, we add the loop variable as the
+current value for its name. Note that it is possible that there is a
+variable of the same name in the outer scope. It would be easy to make
+this an error (emit an error and return null if there is already an
+entry for VarName) but we choose to allow shadowing of variables. In
+order to handle this correctly, we remember the Value that we are
+potentially shadowing in <tt class="docutils literal"><span class="pre">OldVal</span></tt> (which will be null if there is no
+shadowed variable).</p>
+<p>Once the loop variable is set into the symbol table, the code
+recursively codegen’s the body. This allows the body to use the loop
+variable: any references to it will naturally find it in the symbol
+table.</p>

+<p>The final code handles various cleanups: now that we have the “NextVar”
+value, we can add the incoming value to the loop PHI node. After that,
+we remove the loop variable from the symbol table, so that it isn’t in
+scope after the for loop. Finally, code generation of the for loop
+always returns 0.0, so that is what we return from
+<tt class="docutils literal"><span class="pre">ForExprAST::Codegen</span></tt>.</p>
+<p>With this, we conclude the “adding control flow to Kaleidoscope” chapter
+of the tutorial. In this chapter we added two control flow constructs,
+and used them to motivate a couple of aspects of the LLVM IR that are
+important for front-end implementors to know. In the next chapter of our
+saga, we will get a bit crazier and add <a class="reference external" href="LangImpl6.html">user-defined
