--- Comment #12 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Thu Oct 31 13:17:48 2019 New Revision: 277667 URL: https://gcc.gnu.org/viewcvs?rev=277667&root=gcc&view=rev Log: Remove PR 92268 workaround and fix new test failures With the compiler bug fixed we can simplify the __sizable concept to use a return-type-requirement again. I also realised it was redundantly re-checking a subset of the sized_sentinel_for requirements. The compiler fix also revealed bugs in two tests which started to fail and are fixed by this patch. * include/bits/range_access.h (__sizable): Rename to __sentinel_size. Remove workaround for PR c++/92268 and remove redundant requirements that are already checked by sized_sentinel_for. * testsuite/std/ranges/access/cend.cc: Fix failures. * testsuite/std/ranges/access/end.cc: Likewise. Modified: trunk/libstdc++-v3/ChangeLog trunk/libstdc++-v3/include/bits/range_access.h trunk/libstdc++-v3/testsuite/std/ranges/access/cend.cc trunk/libstdc++-v3/testsuite/std/ranges/access/end.cc
