Subject: (movsi matcher): Add nop for moving special register to itself for !TARGET_POWER.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fb81d7cec645615f139cf4f1ff9737112f7769da;p=gcc.git

(movsi matcher): Add nop for moving special register to itself for !TARGET_POWER.

(movsi matcher): Add nop for moving special register to itself
for !TARGET_POWER.
(movhi and movqi matcher): Likewise and add mtjmpr attribute.
Separate MQ from CTR and LR target registers for TARGET_POWER.
