toolchain: gcc: drop 110-Fix-MIPS-PR-84790.patch

2026-05-02T23:18:09Z

The issue reported on the patch has been fixed in GCC 13.4.0[1], 14.2.0[2] and 15.1.0[3]. And we have already removed the GCC 14 patch variant in commit a1b9c28edd72 ("toolchain: gcc: drop 110-Fix-MIPS-PR-84790.patch").

toolchain: gcc: fix include memory against GCC 16

2026-04-27T08:47:10Z

This patch backports a small but important part of the upstream commit: b3f1b9e2aa07 build: Remove INCLUDE_MEMORY [PR117737] Its original commit message fails to mention that the commit also moves the `#include ` to an earlier position within system.h, which is the actual change that we're after in this patch. Building our GCC 14.3 with host GCC 16, the inclusion order starts to matter, which is an issue that was also touched upon by the upstream commits: 9970b576b7e4 Include safe-ctype.h after C++ standard headers, to avoid over-poisoning f6e00226a4ca build: Move sstream include above safe-ctype.h {PR117771] Signed-off-by: Lars Gierth Link: https://github.com/openwrt/openwrt/pull/23095 Signed-off-by: Robert Marko

toolchain: gcc: 14/15: fix libcody compilation with GCC16

2026-04-22T14:50:10Z

libcody will fail to build if building using a GCC16 host compiler, so backport the upstream fix. Signed-off-by: Robert Marko

toolchain/gcc: prevent the use of LDRD/STRD on ARMv5TE

2025-07-22T10:03:05Z

These instructions are for 64-bit load/store. On ARMv5TE, the CPU requires addresses to be aligned to 64-bit. When misaligned, behavior is undefined (effectively either loads the same word twice on LDRD, or corrupts surrounding memory on STRD). On ARMv6 and newer, unaligned access is safe. Removing these instructions for ARMv5TE is necessary, because GCC ignores alignment information in pointers and does unsafe optimizations that have shown up as bugs in various places. This patch was originally added more than 11 years ago in commit b050f87d13b5, but got lost 6 years ago, when gcc 9.1 was added in 88c07c655262. This primarily affects the kirkwood and ixp4xx targets Signed-off-by: Felix Fietkau

toolchain: gcc: 15: fix build error with glibc for aarch64 targets

2025-07-08T12:19:18Z

GCC 14+ fails to build due to libatomic specific -march handling. This build error triggers only with glibc and not with musl libc which is default. It seems that this patch from GCC14 was forgotten when GCC15 support was being added [1].
