From 7542a596010e538ceff56b57dc2c6797c63d73ba Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Fri, 13 Mar 2020 00:41:27 +0100 Subject: [PATCH] package/gcc: disable gcc 9.x for csky When building a toolchain with upstream gcc 9.x the build fail due to several issues. Note: The upstream Binutils support csky target since release 2.32 but the support was never enabled in the Buildroot packaging. So the latest version (2.33.1) was tested here. [upstream gcc 9.x w/ glibc csky fork with binutils csky for or binutils 2.33.1] In file included from : ./../include/libc-symbols.h:534:26: error: '__EI___errno_location' specifies less restrictive attributes than its target '__errno_location': 'const', 'nothrow' [-Werror=missing-attributes] 534 | extern __typeof (name) __EI_##name \ [upstream gcc 9.x w/ glibc 2.30 w/ binutils csky fork] /tmp/ccThLRhb.s: Assembler messages: /tmp/ccThLRhb.s:10: Error: invalid or unsupported encoding in .cfi_personality /tmp/ccThLRhb.s:11: Error: invalid or unsupported encoding in .cfi_lsda [upstream gcc 9.x w/ glibc 2.30 w/ binutils 2.33.1] build/elf/librtld.os: in function `__sync_fetch_and_add_2': libgcc/config/csky/linux-atomic.c:116: undefined reference to `__kernel_cmpxchg' Currenlty, only the toolchain using binutils, gcc, glibc fork produce a working toolchain. So disable gcc 9.x for csky. Signed-off-by: Romain Naour Cc: Yann E.
