[LLVMdev] LLVM ARM VMLA instruction
...de place where we start differentiating between
> cortex-a8 and cortex-a15 for code generation.
Probably most relevant is the combination of features given to each
processor in lib/Target/ARM/ARM.td. This vmul/vmla difference comes
from "FeatureHasSlowFPVMLx", via ARMSubtarget.h's useFPVMLx and
ARMInstrInfo.td's UseFPVMLx.
Cheers.
Tim.
