r271915 - in /trunk/gcc: ChangeLog config/rs600...


Author: segher
Date: Tue Jun  4 16:28:46 2019
New Revision: 271915

URL: https://gcc.gnu.org/viewcvs?rev=271915&root=gcc&view=rev
Log:
rs6000: wv -> v+p7v

"wv" is "v", but only if VSX is enabled (otherwise it's NO_REGS).  So
this patch sets "isa" "p7v" to all alternatives that used "wv" before
(and that do not already need a later ISA), and changes the constraint.


	* config/rs6000/constraints.md (define_register_constraint "wv"):
	Delete.
	* config/rs6000/rs6000.c (rs6000_debug_reg_global): Adjust.
	(rs6000_init_hard_regno_mode_ok): Adjust.
	* config/rs6000/rs6000.h (enum r6000_reg_class_enum): Delete
	RS6000_CONSTRAINT_wv.
	* config/rs6000/rs6000.md: Adjust.
	* config/rs6000/vsx.md: Adjust.
	* doc/md.texi (Machine Constraints): Adjust.
