Subject: [PR99581] Use relaxed memory for more aarch64 memory constraints
X-Git-Tag: basepoints/gcc-12~450
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=be70bb5e4babdf9d3d33e8f4658452038407fa8e;p=thirdparty%2Fgcc.git

[PR99581] Use relaxed memory for more aarch64 memory constraints

The original patch for PR99581 resulted in GCC testsuite regression as
some constraints were not declared as relaxed memory ones.  This patch
fixes this.

gcc/ChangeLog:

	PR target/99581
	* config/aarch64/constraints.md (Utq, UOb, UOh, UOw, UOd, UOty):
	Use define_relaxed_memory_constraint for them.
