This broke when upgrading the minimal version # of GCC required to build the kernel, to a version above what ICC and # Clang claim to be. # # Rather than always including compiler-gcc.h then undefining or # redefining macros in compiler-intel.h or compiler-clang.h, let's # separate out the compiler specific macro definitions into mutually # exclusive headers, do more proper compiler detection, and keep shared # definitions in compiler_types.h. # # Fixes: cafa0010cd51 ("Raise the minimum required gcc version to 4.6") # Reported-by: Masahiro Yamada # Suggested-by: Eli Friedman # Suggested-by: Joe Perches # Signed-off-by: Nick Desaulniers # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < git log --format=%s --max-count=1 815f0ddb346c196018d4d8f8f55c12b83da1de3f # < make -s -j 40 ARCH=nds32 O=/kisskb/build/linus_nds32-defconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- defconfig # make -s -j 40 ARCH=nds32 O=/kisskb/build/linus_nds32-defconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- /kisskb/src/fs/ext4/super.c: In function '__save_error_info.isra.5': /kisskb/src/fs/ext4/super.c:344:2: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(es->s_last_error_func, func, sizeof(es->s_last_error_func)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/fs/ext4/super.c:349:3: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(es->s_first_error_func, func, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(es->s_first_error_func)); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_nds32-defconfig_nds32le # Build took: 0:00:36.958777
