Subject: Fix compile options of pr110279-1.c and pr110279-2.c
X-Git-Tag: basepoints/gcc-15~3304
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6cec7b06b3c8187b36fc05cfd4dd38b42313d727;p=thirdparty%2Fgcc.git

Fix compile options of pr110279-1.c and pr110279-2.c

The two testcases are for targets that support FMA. And
pr110279-2.c assumes reassoc_width of FMUL to be 4.

This patch adds missing options, to fix regression test failures
on nvptx/GCN (default reassoc_width of FMUL is 1) and x86_64
(need "-mfma").

gcc/testsuite/ChangeLog:

	* gcc.dg/pr110279-1.c: Add "-mcpu=generic" for aarch64; add
	"-mfma" for x86_64.
	* gcc.dg/pr110279-2.c: Replace "-march=armv8.2-a" with
	"-mcpu=generic"; limit the check to be on aarch64.
