Subject: testsuite: New effective-target sleep
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a1f70e4111ada4ece7a261a96c3dda1cca309171;p=thirdparty%2Fgcc.git

testsuite: New effective-target sleep

libgfortran calls sleep, which is not available on all targets.

gcc:
	* doc/sourcebuild.texi (Effective-Target Keywords): Document 'sleep'.

gcc/testsuite:
	* lib/target-supports.exp (check_effective_target_sleep): New.
