[LLVMdev] Why llvm-gcc/g++ does not support the 64-bit SPARC ABI (-m64)
My application is 64bit running on Solaris 10 with Sparc. I'd like to use llvm-gcc/g++ to compile it to make it run faster. But in the Release Notes of the latest LLVM release, it says Known problems with the SPARC back-end * The SPARC backend only supports the 32-bit SPARC ABI (-m32); it does not support the 64-bit SPARC ABI (-m64). Why it doesn't support 64bit on sparc? Thanks!
