The kvx GCC adds padding so u32 gets 8-byte # alignment instead of 4. # # I do not know if this happens for upstream architectures in general, # but any compiler has the freedom to insert padding for faster access. # # Use the inline assembler to directly specify the wanted data layout. # This is how we previously did before the breakage. # # Link: https://lore.kernel.org/lkml/20220817161438.32039-1-ysionneau@kalray.eu/ # Link: https://lore.kernel.org/linux-kbuild/31ce5305-a76b-13d7-ea55-afca82c46cf2@kalray.eu/ # Fixes: 7b4537199a4a ("kbuild: link symbol CRCs at final link, removing CONFIG_MODULE_REL_CRCS") # Reported-by: Yann Sionneau <ysionneau@kalray.eu> # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # Tested-by: Yann Sionneau <ysionneau@kalray.eu> # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 60ecfddd7a092f9cbd2398dbc55da3abbb803ff0 # < make -s -j 48 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # < make -s -j 48 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 48 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 48 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 # Build took: 0:03:15.277051
