--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:b984b84cbe4bf026edef2ba37685f3958a1dc1cf commit r13-1578-gb984b84cbe4bf026edef2ba37685f3958a1dc1cf Author: Martin Jambor <mjam...@suse.cz> Date: Fri Jul 8 18:12:26 2022 +0200 testsuite: Fix tree-ssa/alias-access-path-13.c on 32bit platforms (PR 106216) For gcc.dg/tree-ssa/alias-access-path-13.c to work, SRA must think of accesses to foo.inn.val and to foo itself as different ones, i.e. they need to have different offset and size, which on 32bit platforms they do not. Fixed by replacing a dummy long int field of the union with a struct of two integers. Tested by: make -k check-gcc RUNTESTFLAGS="tree-ssa.exp=alias-access-path-13.c" and make -k check-gcc RUNTESTFLAGS="--target_board=unix'{-m32}' tree-ssa.exp=alias-access-path-13.c" on an x86_64-linux, also with patched SRA to verify it still tests the original intent. gcc/testsuite/ChangeLog: 2022-07-08 Martin Jambor <mjam...@suse.cz> PR testsuite/106216 * gcc.dg/tree-ssa/alias-access-path-13.c (union foo): Replace a long int field with a struct that is larger than an int also on 32bit platforms.
