--- Comment #19 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Thomas Schwinge <tschwi...@gcc.gnu.org>: https://gcc.gnu.org/g:e8e0357d129187b24085ce52172c87dbf6c2ecae commit r10-9086-ge8e0357d129187b24085ce52172c87dbf6c2ecae Author: Thomas Schwinge <tho...@codesourcery.com> Date: Wed Nov 25 20:36:55 2020 +0100 Don't create location wrapper nodes within OpenACC clauses This fixes a GCC 11, 10, 9 regression introduced by commit dfd7fdca2ac17d8b823a16700525824ca312ade0 (Subversion r267272) "C++: more location wrapper nodes (PR c++/43064, PR c++/43486)". But: this isn't intending to blame David, because back then, the problem hasn't been visible in the testsuite (or else I'm sure would've been addressed right away) because of our all dear friend: missing testsuite coverage. Thus, for GCC 8, I'm likewise enhancing the testsuite, without the C++ front end code changes. I actually had presumed that there may be an issue for OpenACC: <http://mid.mail-archive.com/874lb9qr2u.fsf@euler.schwinge.homeip.net>, so here we are, two years (and many "wasted" hours...) later... gcc/cp/ * parser.c (cp_parser_omp_var_list_no_open): Assert that array section's 'low_bound', 'length' are not location wrapper nodes. (cp_parser_oacc_all_clauses, cp_parser_oacc_cache): Instantiate 'auto_suppress_location_wrappers'. gcc/testsuite/ * c-c++-common/goacc/cache-3-1.c: New. * c-c++-common/goacc/cache-3-2.c: Likewise. * c-c++-common/goacc/data-clause-1.c: Likewise. * c-c++-common/goacc/data-clause-2.c: Likewise. * c-c++-common/gomp/map-1.c: Adjust. * c-c++-common/gomp/map-2.c: Likewise. * g++.dg/goacc/cache-3-1.C: New. * g++.dg/goacc/cache-3-2.C: Likewise. * g++.dg/goacc/data-clause-1.C: Likewise. * g++.dg/goacc/data-clause-2.C: Likewise. * g++.dg/gomp/map-1.C: Adjust. * g++.dg/gomp/map-2.C: Likewise.
