[LLVMdev] Is there any llvm neon intrinsic that maps to vmla.f32 instruction ?
...ing on different cores.
as theoretical discussion of which code sequence is better is often add odds
with empirically observed results.
Cheers,

Hi Renato,
Indeed problem is with generation of vmla.f64. Affected benchmark is MILC from SPEC 2006 suite and disabling vmlx forwarding gives a 10% speed-up on complete benchmark execution ! So it is worth a try. Now going back to vmla generation through LLMV intrinsic usage. I've looked at .td file and it seems to me that when there is a "pattern" to generate instruction, no
