New Revision: 162225
URL: http://llvm.org/viewvc/llvm-project?rev=162225&view=rev
Log:
Adds the most requested doc for the AST matchers: a reference
of matchers, categorized by type and fully expanded for the
context in which they can be used.
I used a script to generate this documentation which I'll want
to be scrunitized by a code review before checking it in.

+<h1>AST Matcher Reference</h1>
+
+<p>This document shows all currently implemented matchers. The matchers are grouped
+by category and node type they match. You can click on matcher names to show the
+matcher's source documentation.</p>
+
+<p>There are three different basic categories of matchers:
+<ul>
+<li><a href="#decl-matchers">Node Matchers:</a> Matchers that match a specific type of AST node.</li>
+<li><a href="#narrowing-matchers">Narrowing Matchers:</a> Matchers that match attributes on AST nodes.</li>
+<li><a href="#traversal-matchers">Traversal Matchers:</a> Matchers that allow traversal between AST nodes.</li>
+</ul>
+</p>
+
+<p>Within each category the matchers are ordered by node type they match on.
+Note that if a matcher can match multiple node types, it will it will appear
+multiple times. This means that by searching for Matcher<Stmt> you can
+find all matchers that can be used to match on Stmt nodes.</p>
+
+<p>The exception to that rule are matchers that can match on any node. Those
+are marked with a * and are listed in the beginning of each category.</p>
+
+<!-- ======================================================================= -->
+<h2 id="decl-matchers">Node Matchers</h2>
+<!-- ======================================================================= -->
+
+<p>Node matchers are at the core of matcher expressions - they specify the type
+of node that is expected. Every match expression starts with a node matcher,
+which can then be further refined with a narrowing or traversal matcher. All
+traversal matchers take node matchers as their arguments.</p>
+
+<p>For convenience, all node matchers take an arbitrary number of arguments
+and implicitly act as allOf matchers.</p>
+
+<p>Node matchers are the only matchers that support the bind("id") call to
+bind the matched node to the given string, to be later retrieved from the
+match callback.</p>
