* config/rs6000/predicates.md (prefixed_mem_operand): New
predicate.
* config/rs6000/rs6000.md (stack_protect_setdi): Deal with either
address being a prefixed load/store.
(stack_protect_testdi): Deal with either address being a prefixed
load.
2019-10-15 Michael Meissner <meissner@linux.ibm.com>
* config/rs6000/predicates.md (lwa_operand): If the bottom two
bits of the offset for the memory address are non-zero, use PLWA
if prefixed instructions are available.
2019-10-15 Michael Meissner <meissner@linux.ibm.com>
* config/rs6000/rs6000.md (mov<mode>_64bit_dm): Reformat.
(movtd_64bit_nodm): Reformat.
(mov<mode>_32bit): Reformat.
(mov<mode>_softfloat): Reformat.
(FMOVE128_GPR splitter): Reformat.
(DIFD splitter): Reformat.
(TI2 splitter): Reformat.
2019-10-15 Michael Meissner <meissner@linux.ibm.com>
* config/rs6000/rs6000.c (rs6000_insn_cost): Use num_insns insn
attribute if it exists, rather than the insn size. If we use the
insn size, adjust the size to remove the extra size that prefixed
instructions take.
* config/rs6000/rs6000.h (ADJUST_INSN_LENGTH): New target hook to
update the instruction sized if prefixed instructions are used.
* config/rs6000/rs6000.md (prefixed_length attribute): Delete.
(non_prefixed_length attribute): Delete.
(num_insns attribute): New insn attribute to return the number of
instructions.
(max_prefixed_insns attribute): New insn attribute to return the
maximum number of prefixed instructions in an insn.
(length attribute): Do not adjust for prefix instructions here,
punt to ADJUST_INSN_LENGTH.
(mov<mode>_64bit): Set max_prefixed_insns and num_insns.
(movtd_64bit_nodm): Set max_prefixed_insns and num_insns.
(mov<mode>_ppc64): Set max_prefixed_insns and num_insns.
* config/rs6000/vsx.md: (vsx_mov<mode>_64bit): Set
max_prefixed_insns and num_insns.
