+ * config/sparc/sparc.c (sparc_option_override): Remove -mv8plus
+ cpu adjustment.
+ * config/sparc/linux64.h (CC1_SPEC): When defaulting to 64-bit,
+ append -mcpu=v9 when -mv8plus is given.
+
+ * config/sparc/sparc.h (SECONDARY_MEMORY_NEEDED): We can move
+ between float and non-float regs when VIS3.
+ * config/sparc/sparc.c (eligible_for_restore_insn): We can't
+ use a restore when the source is a float register.
+ (sparc_split_regreg_legitimate): When VIS3 allow moves between
+ float and integer regs.
+ (sparc_register_move_cost): Adjust to account for VIS3 moves.
+ (sparc_preferred_reload_class): On 32-bit with VIS3 when moving an
+ integer reg to a class containing EXTRA_FP_REGS, constrain to
+ FP_REGS.
+ (sparc_secondary_reload): On 32-bit with VIS3 when moving between
+ float and integer regs we sometimes need a FP_REGS class
+ intermediate move to satisfy the reload. When this happens
+ specify an extra cost of 2.
