[LLVMdev] llvm-gcc 4.0 question

[Jose Rangel]

Hi Dale,

Thanks for getting back. I may not be able to switch to llvm 4.2 at this
time. I did try:

llvm-gcc --emit-llvm -c sumarray.c -o sumarray.bc
llc -march=ppc32 sumarray.bc
gcc -arch ppc sumarray.s

And this produced a ppc binary that worked (at least in this case).

Do you know if this approach is worthwhile?

Thx,

Jose

llvm-gcc-4.0 is no longer maintained.  Use llvm-gcc-4.2.
