Subject: testsuite: Disable strub on AIX.
X-Git-Tag: basepoints/gcc-15~3301
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9773ca519864e2e0706424b805c3314f1fbe7d10;p=thirdparty%2Fgcc.git

testsuite: Disable strub on AIX.

AIX does not support stack scrubbing. Set strub as unsupported on AIX
and ensure that testcases check for strub support.

gcc/testsuite/ChangeLog:
	* c-c++-common/strub-unsupported-2.c: Require strub.
	* c-c++-common/strub-unsupported-3.c: Same.
	* c-c++-common/strub-unsupported.c: Same.
	* lib/target-supports.exp (check_effective_target_strub): Return 0
	for AIX.
