--- Comment #20 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Thomas Schwinge <tschwi...@gcc.gnu.org>: https://gcc.gnu.org/g:c650b557cb01f97bebb894aa68e5e74c2147c395 commit r15-8053-gc650b557cb01f97bebb894aa68e5e74c2147c395 Author: Thomas Schwinge <tho...@codesourcery.com> Date: Mon Jul 11 22:36:39 2022 +0200 GCN, nvptx: Don't default-disable libstdc++ build In addition to making libstdc++ itself available, this, via enabling 'build-gcc/*/libstdc++-v3/scripts/testsuite_flags', in particular also makes the standard C++ headers available to 'make check-gcc-c++'. With that, there are a lot of FAIL/UNRESOLVED -> PASS progressions, where we previously ran into, for example: FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for errors, line 6) FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for excess errors) Excess errors: [...]/gcc/testsuite/g++.dg/coroutines/coro.h:132:10: fatal error: cstdlib: No such file or directory Similarly, there are a lot of FAIL/UNRESOLVED -> UNSUPPORTED "progressions" due to 'sorry, unimplemented: exception handling not supported'. The 'make check-target-libstdc++-v3' results don't look too bad, either. This also reverts Subversion r221362 (Git commit d94fae044da071381b73a2ee8afa874b14fa3820) "No libstdc++ for nvptx", and commit 2f4f3c0e9345805160ecacd6de527b519a8c9206 "No libstdc++ for GCN". With libstdc++ now available, libgrust gets enabled, which we in turn again have to disable, for 'sorry, unimplemented: exception handling not supported' reasons. PR target/92713 PR target/101544 * configure.ac [GCN, nvptx] (noconfigdirs): Don't add 'target-libstdc++-v3'. Add 'target-libgrust'. * configure: Regenerate. gcc/ * config/gcn/gcn.h (LIBSTDCXX): Don't set. * config/nvptx/nvptx.h (LIBSTDCXX): Likewise.
