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.

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

2025-05-12T09:13:20Z

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.

toolchain: gcc: Backport patch to fix mips16 linking

Backport patch from upstream GCC 14 branch which fixes linking with MIPS16 on the pistachio target. This fixes the following link problem: ``` /builder/shared-workdir/build/staging_dir/toolchain-mipsel_24kc+24kf_gcc-14.2.0_musl/lib/gcc/mipsel-openwrt-linux-musl/14.2.0/../../../../mipsel-openwrt-linux-musl/bin/ld.bfd: ./liblua.so: undefined reference to `__mips16_ledf2' /builder/shared-workdir/build/staging_dir/toolchain-mipsel_24kc+24kf_gcc-14.2.0_musl/lib/gcc/mipsel-openwrt-linux-musl/14.2.0/../../../../mipsel-openwrt-linux-musl/bin/ld.bfd: ./liblua.so: undefined reference to `__mips16_call_stub_df_2' /builder/shared-workdir/build/staging_dir/toolchain-mipsel_24kc+24kf_gcc-14.2.0_musl/lib/gcc/mipsel-openwrt-linux-musl/14.2.0/../../../../mipsel-openwrt-linux-musl/bin/ld.bfd: ./liblua.so: undefined reference to `__mips16_muldf3' ``` Link: https://github.com/openwrt/openwrt/pull/18688 Signed-off-by: Hauke Mehrtens

Revert "toolchain: gcc: make config consistent with glibc/musl"

2025-05-02T17:30:47Z

This reverts commit 57841c83d9c1503a19212766639d17ae5019bb8c. This is completely breaking the inital GCC configuration and most likely was not even compile tested, so revert until fixed. Signed-off-by: Robert Marko

toolchain: gcc: make config consistent with glibc/musl

2025-05-02T15:27:33Z

I've observed configuration drift for GCC between musl and glibc (especially it's final stage): # musl lt_cv_prog_compiler_static_works=yes lt_cv_prog_compiler_static_works_CXX=yes lt_cv_sys_max_cmd_len=1572864 # glibc lt_cv_prog_compiler_static_works=no lt_cv_prog_compiler_static_works_CXX=no lt_cv_sys_max_cmd_len=512 These changes should prevent this issue in future: export lt_cv_prog_compiler_static_works=yes export lt_cv_prog_compiler_static_works_CXX=yes export lt_cv_sys_max_cmd_len=1572864 Also: - provide custom autotools/libtool variables via properly named variable ("GCC_CONFIGURE_VARS"), - move variables from "GCC_MAKE" to "GCC_CONFIGURE_VARS" (at this moment only "gcc_cv_libc_provides_ssp=yes" for musl), - propagate it's usage for both "./configure" and "make".

toolchain: gcc: switch default to 14
