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].

toolchain: gcc: drop GCC11

2025-05-26T17:20:56Z

There is no practical value in keeping GCC11 around, as even OpenWrt 23.05 uses GCC12 as the default one, so drop it. Signed-off-by: Robert Marko

toolchain: gcc: backport patch to fix ICE with PowerPC targets

2025-05-14T09:23:34Z

During the build of perl, the following ICE was reported in https://github.com/openwrt/packages/issues/24565 when targeting PowerPC: during RTL pass: reload blocksort.c: In function 'mainSort.isra': blocksort.c:1011:1: internal compiler error: in patch_jump_insn, at cfgrtl.cc:1303 1011 | } | ^ 0x7d49cee29d8f __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 0x7d49cee29e3f __libc_start_main_impl ../csu/libc-start.c:392 Please submit a full bug report, with preprocessed source (by using -freport-bug). Please include the complete backtrace with any bug report. See for instructions. The same issue also caused the CI failures in https://github.com/openwrt/packages/pull/26501. The issue only occurs with GCC 14.2.0, but not with the head of the releases/gcc-14 maintenance branch; a bisect found that this patch fixes it.
