[LLVMdev] how to disable sse and avx

[zhi chen]

Hello,

I want to disable LLVM to use any SIMD registers like sse and avx. I tried
-mno-sse and -mno-avx on my Core i7 machine. It seems that the generated
assembly still uses xmm registers. Is there any way for LLVM to only use
scalar registers?

Thanks,
Zhi
