[llvm-commits] LLVM patch to support ARM fused multiply add/subtract instructions

[Anton Korobeynikov]

Hi James,

> I'm not 100% happy with this patch. The implementation means that -mattr=+neon,+vfp4 does not enable neon-vfp4, which I think is rather confusing.
> I'd much prefer the predicate to be rewritten such that hasNEONVFP4() === hasNEONVFP4 || (hasVFP4 && hasNEON), what do you think?
Is it possible for a core to have vfpv4, but have "previous" neon?
VFPv3-like? Or it's pretty tied situation? So, on VFPv4 core NEON will
also always be VFPv4 ?
