--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Thomas Schwinge <tschwi...@gcc.gnu.org>: https://gcc.gnu.org/g:d3bdc33784c857668503b30368ae50a8d2fca274 commit r12-8853-gd3bdc33784c857668503b30368ae50a8d2fca274 Author: Thomas Schwinge <tho...@codesourcery.com> Date: Mon May 2 15:15:26 2022 +0200 Make 'c-c++-common/goacc/kernels-decompose-pr100400-1-*.c' behave consistently, regardless of checking level Fix-up for commit c14ea6a72fb1ae66e3d32ac8329558497c6e4403 "Catch 'GIMPLE_DEBUG' misbehavior in OpenACC 'kernels' decomposition [PR100400, PR103836, PR104061]". For C++ compilation of 'c-c++-common/goacc/kernels-decompose-pr100400-1-2.c', we first emit a 'sorry' diagnostic, and then a 'gcc_unreachable' (or 'internal_error', see below) diagnostic, but for example, for '--enable-checking=release' (thus, '!CHECKING_P'), the second one may actually be turned into a 'confused by earlier errors, bailing out' diagnostic. (See 'gcc/diagnostic.cc:diagnostic_report_diagnostic': "When not checking, ICEs are converted to fatal errors when an error has already occurred.") Thus, make 'c-c++-common/goacc/kernels-decompose-pr100400-1-2.c' behave consistently via '-Wfatal-errors', and thus only matching the 'sorry' diagnostic. For example, for '--enable-checking=no' (thus, '!ENABLE_ASSERT_CHECKING'), a call to 'gcc_unreachable' cannot be assumed emit an 'internal_error'-like diagnostic, so explicitly call 'internal_error' in 'gcc/omp-oacc-kernels-decompose.cc:visit_loops_in_gang_single_region', in the 'GIMPLE_OMP_FOR' case, to avoid regressing 'c-c++-common/goacc/kernels-decompose-pr100400-1-3.c', and 'c-c++-common/goacc/kernels-decompose-pr100400-1-4.c'. PR middle-end/100400 gcc/ * omp-oacc-kernels-decompose.cc (visit_loops_in_gang_single_region) <GIMPLE_OMP_FOR>: Explicitly call 'internal_error'. gcc/testsuite/ * c-c++-common/goacc/kernels-decompose-pr100400-1-2.c: Specify '-Wfatal-errors'.
