Hongyu Wang <hongyuw at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hongyuw at gcc dot gnu.org --- Comment #1 from Hongyu Wang <hongyuw at gcc dot gnu.org> --- We haven't disable AMD ISAs like XOP/FMA4 as it will not invoke with APX. Quoted from Richard's comment > We haven’t disabled EGPR for 3DNOW/XOP/LWP/FMA4/TBM instructions, as they will > be co-operated with -mapxf. We can disable EGPR for them if AMD guys requires. I think most of these are retired by now, so it's unlikely an implementation providing these and also APX will appear.
