llvm dev - Mar 2010 - [LLVMdev] Help with understanding LLVM

Hi,

I am trying to understand LLVM. Can an expert tell me how to compare the
kaleidoscope implementation with the LLVM's compiler implementation. I mean
can anyone tell me about the lexer, parser, codegen related .cpp and .h
files inside the LLVM solution project. I would like to understand the
LLVM's compiler in the same way that the kaleidoscope compiler is explained.


Thanks a lot.

Hi Kalyan,

That's a tall order, and I don't think we would be able to help you in
general. However, there is a lot of documentation on LLVM (optimization passes,
analysis, code generation, dead chicken waving) here:

	http://llvm.org/docs

For the front-end (lexer, parser, semantic analysis, voodoo), you will want to
look at these web pages:

	http://clang.llvm.org/

Good luck!

Hi,

I went through the front end part of the clang (a bit atleast) and I went
through some of the documentation on the llvm.org website and was trying to
know what happens after the front end is done with the code. Could you tell
me how does llvm comes into picture as soon as clang part of the interface
deals with the source code.

Thanks.
