From 39f89e0daf6933fc888b79aa15f358b145c212ee Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Thu, 18 Jul 2024 09:22:10 +0200 Subject: testsuite: Fix up builtin-clear-padding-3.c for -funsigned-char As reported on gcc-regression, this test FAILs on aarch64, but my r15-2090 change didn't change anything on the generated assembly, just added the forgotten dg-do run directive to the test, so the test has been failing forever, just we didn't know it. I can actually reproduce it on x86_64 with -funsigned-char too, s2.b.a has int type and -1 is stored to it, so we should compare it against -1 rather than (char) -1; the latter is appropriate for testing char fields into which we've stored -1. 2024-07-18 Jakub Jelinek * c-c++-common/torture/builtin-clear-padding-3.c (main): Compare s2.b.a against -1 rather than (char) -1.
