Subject: libstdc++: Fix deleted overload of __absu(bool)
X-Git-Tag: basepoints/gcc-12~5324
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0789600c597ff1f8ac06e84ffb584c853d1675d1;p=thirdparty%2Fgcc.git

libstdc++: Fix deleted overload of __absu(bool)

libstdc++-v3/ChangeLog:

	* include/std/numeric (__detail::__absu(bool)): Make deleted
	function a function template, so it will be chosen for calls
	with an explicit template argument list.
	* testsuite/26_numerics/gcd/gcd_neg.cc: Add dg-prune-output.
	* testsuite/26_numerics/lcm/lcm_neg.cc: Likewise.
