[LLVMdev] Can't use SSE4.2 instructions
Hi,
I'm trying to use the SSE4.2's instruction _mm_crc32_u64 and also
added -msse4.2 flag in the makefile, but yet I get this error when I try to
compile my code with clang/llvm.
LLVM ERROR: Cannot select: intrinsic %llvm.x86.sse42.crc32.64.64
I also tried to pass -march=native, but still no luck.

If you're feeling ambitious ;), you could try -emit-llvm and see what's
coming across the interface.
