[llvm-commits] Please review: FMA3 instructions set

[Demikhovsky, Elena]

I did not update llvm.fma.f32/64. Should it be directly mapped to a scalar instruction, like int_x86_fma4_vfmadd_ss int_x86_fma4_vfmadd_sd ?

Hi Elena

I notice you make use of the x86 fma intrinsic.  Can you also please make sure your code works with the llvm.fma.f32 and llvm.fma.f64 intrinsics.  An example for these is already in X86/fma.ll.

Note we may also want to remove some of the intrinsics you have if they are identical behaviorally to llvm.fma.f32/64.

Thanks,
Pete
