--- Comment #11 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:d6479050ecef10fd5e67b4da989229e4cfac53ee commit r14-9204-gd6479050ecef10fd5e67b4da989229e4cfac53ee Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Feb 28 09:59:45 2024 +0100 graphite: Fix non-INTEGER_TYPE integral comparison handling [PR114041] The following testcases are miscompiled, because graphite ignores boolean, enumerated or _BitInt comparisons, rewrites the code as if the comparisons were always true or always false. The INTEGER_TYPE checks were initially added in r6-2239 but at that point it was both in add_conditions_to_domain and in parameter_index_in_region. Later on the check was also added to stmt_simple_for_scop_p, and finally r8-3931 changed the stmt_simple_for_scop_p check to INTEGRAL_TYPE_P and turned the parameter_index_in_region -> assign_parameter_index_in_region into INTEGRAL_TYPE_P assertion, but the add_conditions_to_domain check for INTEGER_TYPE remained. The following patch uses INTEGRAL_TYPE_P to complete the change. 2024-02-28 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/114041 * graphite-sese-to-poly.cc (add_conditions_to_domain): Check for INTEGRAL_TYPE_P check rather than INTEGER_TYPE. * gcc.dg/graphite/run-id-pr114041-1.c: New test. * gcc.dg/graphite/run-id-pr114041-2.c: New test.
