Subject: [arm] Use -Os for stack-protector-[56].c tests
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f694a0d2edc025cb54657cb804960f97a31fbda2;p=gcc.git

[arm] Use -Os for stack-protector-[56].c tests

Using -O2 made the tests subject to LDRD vs. LDM tuning.
The simplest fix seems to be to use -Os, so that LDM is
unequivocally a win.

gcc/testsuite/
	* gcc.target/arm/stack-protector-5.c: Use -Os rather than -O2.
	* gcc.target/arm/stack-protector-6.c: Likewise.
