--- Comment #2 from Tamar Christina <tnfchris at gcc dot gnu.org> --- Author: tnfchris Date: Tue Oct 22 14:25:38 2019 New Revision: 277291 URL: https://gcc.gnu.org/viewcvs?rev=277291&root=gcc&view=rev Log: Arm: Fix arm libsanitizer bootstrap failure Glibc has recently introduced changed to the mode field in ipc_perm in commit 2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this means that the mode field no longer has the same size. This causes an assert failure against libsanitizer's internal copy of ipc_perm. Since this change can't be easily detected I am adding arm to the list of targets that are excluded from this check. libsanitizer doesn't use this field (and others, it in fact uses only 1 field) so this check can be ignored. Padding bits were used by glibc when the field was changed so sizeof and offsets of the remaining fields should be the same. libsanitizer/ChangeLog: PR sanitizer/92154 * sanitizer_common/sanitizer_platform_limits_posix.cpp (defined): Cherry-pick compiler-rt revision r375220. Modified: trunk/libsanitizer/ChangeLog trunk/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp
