Subject: testsuite: Skip module_cmi_p and related unsupported module test
X-Git-Tag: basepoints/gcc-14~919
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5344482c4d3ae0618fa8f5ed38f8309db43fdb82;p=thirdparty%2Fgcc.git

testsuite: Skip module_cmi_p and related unsupported module test

When a multi-source module is found to be unsupported, we fail
module_cmi_p and subsequent sources.  Override proc unsupported to
mark the result in module_do, and test it to skip module_cmp_p and
subsequent related tests.


for  gcc/testsuite/ChangeLog

	* g++.dg/modules/modules.exp: Override unsupported to update
	module_do, and test it after dg-test.
