--- Comment #19 from Alan Modra <amodra at gcc dot gnu.org> --- Author: amodra Date: Mon Feb 15 23:29:17 2016 New Revision: 233438 URL: https://gcc.gnu.org/viewcvs?rev=233438&root=gcc&view=rev Log: [RS6000] reload_vsx_from_gprsf splitter This is PR68973 part 2, caused by the reload_vsx_from_gprsf splitter emitting an invalid move. The patch also fixes uses of TFmode, which cannot now be assumed to be IBM double-double. PR target/68973 * config/rs6000/rs6000.md (reload_vsx_from_gprsf): Rewrite splitter. (p8_mtvsrd_df, p8_mtvsrd_sf): New. (p8_mtvsrd_1, p8_mtvsrd_2): Delete. (p8_mtvsrwz): New. (p8_mtvsrwz_1, p8_mtvsrwz_2): Delete. (p8_xxpermdi_<mode>): Take two DF inputs rather than one TF. (p8_fmrgow_<mode>): Likewise. (reload_vsx_from_gpr<mode>): Make clobber IF. Adjust for above changes. (reload_fpr_from_gpr<mode>): Similarly. Use "d" for op0 constraint. (reload_vsx_from_gprsf): Use p8_mtvsrd_sf rather than attempting to use movdi_internal64. Remove op0_di. * config/rs6000/vsx.md (vsx_xscvspdpn_directmove): Make op1 SFmode.
