rs6000.h (enum r6000_reg_class_enum): Add new constraints: wu, ww, and wy.
2013-09-20 Michael Meissner <meissner@linux.vnet.ibm.com>
* config/rs6000/rs6000.h (enum r6000_reg_class_enum): Add new
constraints: wu, ww, and wy. Repurpose wv constraint added during
power8 changes. Put wg constraint in alphabetical order.
* config/rs6000/rs6000.opt (-mvsx-scalar-float): New debug switch
for future work to add ISA 2.07 VSX single precision support.
(-mvsx-scalar-double): Change default from -1 to 1, update
documentation comment.
(-mvsx-scalar-memory): Rename debug switch to -mupper-regs-df.
(-mupper-regs-df): New debug switch to control whether DF values
can go in the traditional Altivec registers.
(-mupper-regs-sf): New debug switch to control whether SF values
can go in the traditional Altivec registers.
* config/rs6000/rs6000.c (rs6000_debug_reg_global): Print wu, ww,
and wy constraints.
(rs6000_init_hard_regno_mode_ok): Use ssize_t instead of int for
loop variables. Rename -mvsx-scalar-memory to -mupper-regs-df.
Add new constraints, wu/ww/wy. Repurpose wv constraint.
(rs6000_debug_legitimate_address_p): Print if we are running
before, during, or after reload.
(rs6000_secondary_reload): Add a comment.
(rs6000_opt_masks): Add -mupper-regs-df, -mupper-regs-sf.
* config/rs6000/constraints.md (wa constraint): Sort w<x>
constraints. Update documentation string.
(wd constraint): Likewise.
(wf constraint): Likewise.
(wg constraint): Likewise.
(wn constraint): Likewise.
(ws constraint): Likewise.
(wt constraint): Likewise.
(wx constraint): Likewise.
(wz constraint): Likewise.
(wu constraint): New constraint for ISA 2.07 SFmode scalar
instructions.
(ww constraint): Likewise.
(wy constraint): Likewise.
(wv constraint): Repurpose ISA 2.07 constraint that we not used in
the previous submissions.
* doc/md.texi (PowerPC and IBM RS6000): Likewise.
