--- Comment #35 from CVS 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:e0ce885851dfd926c0cfe6f23a2debc87ea2bb9d commit r12-7951-ge0ce885851dfd926c0cfe6f23a2debc87ea2bb9d Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Apr 1 11:49:40 2022 +0200 testsuite: Add further zero size elt passing tests [PR102024] As discussed in PR102024, zero width bitfields might not be the only ones causing ABI issues at least on mips, zero size arrays or (in C only) zero sized (empty) structures can be problematic too. The following patch adds some coverage for it too. Tested on x86_64-linux with make check-gcc check-g++ RUNTESTFLAGS='ALT_CC_UNDER_TEST=gcc ALT_CXX_UNDER_TEST=g++ --target_board=unix\{-m32,-m64\} compat.exp=pr102024*' make check-gcc check-g++ RUNTESTFLAGS='ALT_CC_UNDER_TEST=clang ALT_CXX_UNDER_TEST=clang++ --target_board=unix\{-m32,-m64\} compat.exp=pr102024*' with gcc/g++ 10.3 and clang 11. Everything but (expectedly) FAIL: gcc.dg/compat/pr102024 c_compat_x_tst.o-c_compat_y_alt.o execute FAIL: gcc.dg/compat/pr102024 c_compat_x_alt.o-c_compat_y_tst.o execute for -m64 ALT_CC_UNDER_TEST=gcc passes. 2022-04-01 Jakub Jelinek <ja...@redhat.com> PR target/102024 * gcc.dg/compat/pr102024_test.h: Add further tests with zero sized structures and arrays. * g++.dg/compat/pr102024_test.h: Add further tests with zero sized arrays.
