[LLVMdev] Idea for Google Summer Code : C Compiler for EFI Byte Code implement in LLVM

[琬菁楊]

Hello Tristan and all,

I have already know that if I want to do this feature(c -> EFI Byte code)
for GCC
I should further modify the GCC front end(parser) to solve the problem (the
size
of pointer is determined at run time).

I have read a powerpoint about LLVM (
http://llvm.org/pubs/2008-10-04-ACAT-LLVM-Intro.pdf)
It is the LLVM-GCC design graph (
http://www.im.ntu.edu.tw/~b95030/llvm_gcc.png<http://www.im.ntu.edu.tw/%7Eb95030/llvm_gcc.png>
).
According to the above discussion , LLVM IR doesn't care about the size of
pointers.
I am wondering how could LLVM support dynamic pointer size model without
modifying
GCC front end??

thanks

ching
