Subject: profopt-execute: unset testname_with_flags if create_gcov fails
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b46314c78061a5156bac44a317c87d32b00d4295;p=gcc.git

profopt-execute: unset testname_with_flags if create_gcov fails

When diffing test results, there sometimes occur spurious "New tests
that PASS" / "Old tests that passed, that have disappeared" messages.
The reason is that if create_gcov is not installed, then the cached
testname_with_flags is not cleared and is carried over to the next
test.

	* lib/profopt.exp: Unset testname_with_flags if create_gcov
	fails.
