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

[James Molloy]

Hi Anton,

I can't think of anything you missed from your list (apart from that VMLA is also in VFPv3). Granted NEONv2 without VFPv4 might be difficult to support, but I see that being a pretty unlikely combination anyway...

Cheers,

James

Cameron,

Right. Maybe -ffast-math should imply this flag as well.
