[LLVMdev] llvm/dragonegg as drop-in replacement to gcc

[Ashay Rane]

Hello,

Does anyone know of any effort to create a drop-in replacement to gcc, g++
and gfortran using llvm/dragonegg? From what I understand, the link step is
complicated because one needs to use llvm-ld to convert the bitcode to a
native binary and not all options to gcc/g++/gfortran can be passed to
llvm-ld. I believe I could use llvm-as to compile bitcode to x86 assembly
and then link everything together using gcc/g++/gfortran but this approach
poses problems when building / using libraries (`.a' files). [
https://github.com/travitch/whole-program-llvm] seems to come close but it
works only for gcc and g++ (not gfortran). Clang doesn't support OpenMP and
hence doesn't look like a viable option at this time. Any other ways of
using dragonegg in a transparent way?

Thanks much!
Ashay
