Subject: darwin, testsuite - fix PR58321
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ab904df5f9063cf3075ae20b97cf4df9e6612cc1;p=gcc.git

darwin, testsuite - fix PR58321

Darwin doesn't emit a .file directive by default
and one of the scan-asm hits for ELF targets comes from
this directive. Adjust for Darwin and explain.

	PR testsuite/58321
	* gcc.target/i386/memcpy-strategy-3.c: Adjust count for Darwin and
	add a comment as to the reason for the difference.
	* gcc.target/i386/memset-strategy-1.c: Likewise.
