Arghh, forgot the the patch once again. [gcc] 2015-11-10 Michael Meissner <meissner@linux.vnet.ibm.com> <patch #10> * config/rs6000/constraints.md (wb constraint): New constraint for ISA 3.0 d-form scalar addressing. * config/rs6000/rs6000.c (mode_supports_vmx_dform): Add support for ISA 3.0 D-form addressing to load SFmode/DFmode scalars into Altivec registers. Add wb constraint for Altivec registers with D-form addressing. If we have ISA 3.0 d-form support, undo secondary reload support for using FPR registers if we want to do D-form addressing. (rs6000_debug_reg_global): Likewise. (rs6000_setup_reg_addr_masks): Likewise. (rs6000_init_hard_regno_mode_ok): Likewise. (rs6000_secondary_reload): Likewise. (rs6000_preferred_reload_class): Likewise. (rs6000_secondary_reload_class): Likewise. * config/rs6000/rs6000.h (enum r6000_reg_class_enum): Add wb constraint. * config/rs6000/rs6000.md (f32_lr2 mode attribute): Add support for ISA 3.0 SFmode/DFmode d-form addressing to Altivec registers. (f32_lm2): Likewise. (f32_li2): Likewise. (f32_sr2): Likewise. (f32_sm2): Likewise. (f32_si2): Likewise. (f64_p9): Likewise. (extendsfdf2_fpr): Likewise. (mov<mode>_hardfloat): Likewise. (mov<mode>_hardfloat32): Likewise. (mov<mode>_hardfloat64): Likewise. * doc/md.texi (RS/6000 constraints): Document wb constraint. Fixup we constraint documentation. [gcc/testsuite] 2015-11-10 Michael Meissner <meissner@linux.vnet.ibm.com> * gcc.target/powerpc/dform-1.c: New test. * gcc.target/powerpc/dform-2.c: Likewise. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meissner@linux.vnet.ibm.com, phone: +1 (978) 899-4797
