[LLVMdev] RE : Is there any llvm neon intrinsic that maps to vmla.f32 instruction ?

[Lang Hames]

Hi Sebastien,

How many extra vmlas did you see in 433.milc due to disabling
-vmlx-forwarding?
As I mentioned earlier, I saw only two additional integer vmlx instructions
when I tested.

Could you send me your 433.milc compile setup? (os, flags, compiler
version, etc.). I'd like to try to reproduce your results.

Cheers,
Lang.
