llvm dev - Mar 2009 - [LLVMdev] Rolling my own LLVM assembly language parser

Thank you both for your answers.

The only reason I was interested in not using the built-in parsing library
was that it would give me more flexibility over the language I program in,
but if it means brushing up on my C++ then this isn't too much of a problem
either.

With regards to using the in-memory LLVM, that's also a good approach.
However, I was thinking of structuring my thesis work as standalone tools
(much like llvm-as and the others) as it would help me structure my work
better. I hope this makes sense.

Best,

James

You can achieve the 'standalone tools' effect using LLVM bitcode,
which is a binary IR format.

Then you can have:
source code -> [llvm-gcc frontend] -> bc
bc -> [your tool using llvm bitcode reader writer library, doing
whatever mutations to the IR you want and spitting out bc again] -> bc
bc -> [llvm backend (llc)/llvm-as/...] -> native code.

Doesn't that meet your requirements?

That sounds promising, as far as I can tell!

Thanks very much. It's the end of the day now, but I'll be getting stuck
in
tomorrow.

Best,

James
