--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alexandre Oliva <aol...@gcc.gnu.org>: https://gcc.gnu.org/g:261ffe685f3865ea61599d61d6b32b92e476a342 commit r15-6771-g261ffe685f3865ea61599d61d6b32b92e476a342 Author: Alexandre Oliva <ol...@adacore.com> Date: Fri Jan 10 09:32:20 2025 -0300 testsuite: generalize ifcombine field-merge tests [PR118025] A number of tests that check for specific ifcombine transformations fail on AVR and PRU targets, whose type sizes and alignments aren't conducive of the expected transformations. Adjust the expectations. Most execution tests should run successfully regardless of the transformations, but a few that could conceivably fail if short and char have the same bit width now check for that and bypass the tests that would fail. Conversely, one test that had such a runtime test, but that would work regardless, no longer has that runtime test, and its types are narrowed so that the transformations on 32-bit targets are more likely to be the same as those that used to take place on 64-bit targets. This latter change is somewhat obviated by a separate patch, but I've left it in place anyway. for gcc/testsuite/ChangeLog PR testsuite/118025 * gcc.dg/field-merge-1.c: Skip BIT_FIELD_REF counting on AVR and PRU. * gcc.dg/field-merge-3.c: Bypass the test if short doesn't have the expected size. * gcc.dg/field-merge-8.c: Likewise. * gcc.dg/field-merge-9.c: Likewise.
