Subject: Simplify SH DImode add, sub, neg patterns.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a1443cff0d845ddcb1d114f0864e29c89e37f260;p=gcc.git

Simplify SH DImode add, sub, neg patterns.

	* config/sh/sh.md (adddi3, subdi3, negdi2, abs<mode>2): Remove
	define_expand patterns.
	(adddi3_compact): Rename to adddi3.
	(subdi3_compact): Rename to subdi3.
	(*negdi2): Rename to negdi2.
	(*abs<mode>2): Rename to abs<mode>2.
