Subject: [gcc/devel/c++-coroutines] libstdc++: Fix deleted overload of __absu(bool)
Date: Mon, 31 Aug 2020 19:49:18 +0000 (GMT)	[thread overview]

commit 0789600c597ff1f8ac06e84ffb584c853d1675d1
Author: Jonathan Wakely <jwakely@redhat.com>

    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.
