(https://lkml.org/lkml/2014/4/8/272) # # The code snippet from the submitted patch was as follows: # # # We need HJ Lu's Linux binutils because mainline binutils does not # # support mixing assembler and LTO code in the same ld -r object. # # XXX check if the gcc plugin ld is the expected one too # # XXX some Fedora binutils should also support it. How to check for that? # ifeq ($(call ld-ifversion,-ge,22710001,y),y) # ... # # However, GCC LTO was not merged into the mainline after all. # (https://lkml.org/lkml/2014/4/8/272) # # So, the 4th and 5th fields were never used, and finally removed by # commit 0d61ed17dd30 ("ld-version: Drop the 4th and 5th version # components"). # # Since then, the last 4-digits returned by this script is always zeros. # # Remove the meaningless last 4-digits. This makes the version format # consistent with GCC_VERSION, CLANG_VERSION, LLD_VERSION. # # Signed-off-by: Masahiro Yamada # Acked-by: Will Deacon # Acked-by: Thomas Bogendoerfer # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 49362029a00b1c8af81d635333806e3d0dc8fdc1 # < make -s -j 32 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # < make -s -j 32 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 32 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 32 ARCH=x86 O=/kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/kbuild_x86_64_defconfig_x86_64-gcc8 # Build took: 0:02:46.627481
