<p class=MsoNormal>Is there a guide that explains the purpose of each?
Obviously the ones in an “example” folder are examples, but what about
everything else? Is there a guide to the LLVM components or source code?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If there are no such guides, could someone tell me which
parts of LLVM are needed for “minimal” JIT compilation? I would like to create
small amounts of IR at run-time, compile them in-memory, and run them.
Basically I would like to do as described at <a
href="http://www.codeproject.com/KB/cpp/runtime_compile.aspx">http://www.codeproject.com/KB/cpp/runtime_compile.aspx</a>,
except that (in order to minimize the code size), I would like to omit most/all
optimizations.<o:p></o:p></p>
