X-Git-Tag: basepoints/gcc-13~4238
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b790acc2207d69b4ebc0f4addd34a0aa32ec6cf;p=thirdparty%2Fgcc.git

libstdc++: Remove unary_function base classes from std::thread tests

std::thread does not care if a function object is adaptable, so there is
no need to derive from the deprecated std::unary_function class in these
tests.

Signed-off-by: Jonathan Wakely <jwakely@redhat.com>

libstdc++-v3/ChangeLog:

	* testsuite/30_threads/thread/cons/3.cc: Remove derivation from
	std::unary_function.
	* testsuite/30_threads/thread/cons/4.cc: Likewise.
	* testsuite/30_threads/thread/cons/5.cc: Likewise.
