------- Comment #10 from rguenth at gcc dot gnu dot org 2008-11-22 15:03 ------- We should have -mfma to enable a fused multiply-add instruction that is available when enabling either -msse5 or -mavx. -mfma should not itself enable any of the instruction set enabling features.
HJ, why did you need -mfma and could not have used -mfused-madd for this? IMHO -mfma is confusing and should be removed. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rguenth at gcc dot gnu dot | |org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38201
