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 <yamada.masahiro@socionext.com> # Suggested-by: Eli Friedman <efriedma@codeaurora.org> # Suggested-by: Joe Perches <joe@perches.com> # Signed-off-by: Nick Desaulniers <ndesaulniers@google.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < git log --format=%s --max-count=1 815f0ddb346c196018d4d8f8f55c12b83da1de3f # < make -s -j 8 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- axs101_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # yes \n \| make -s -j 8 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 8 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- In file included from /kisskb/src/include/asm-generic/bug.h:18:0, from /kisskb/src/arch/arc/include/asm/bug.h:32, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/mmdebug.h:5, from /kisskb/src/include/linux/gfp.h:5, from /kisskb/src/include/linux/slab.h:15, from /kisskb/src/mm/nobootmem.c:14: /kisskb/src/mm/nobootmem.c: In function '__free_pages_memory': /kisskb/src/include/linux/kernel.h:845:29: warning: comparison of distinct pointer types lacks a cast [enabled by default] (!!(sizeof((typeof(x) )1 == (typeof(y) )1))) ^ /kisskb/src/include/linux/kernel.h:859:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^ /kisskb/src/include/linux/kernel.h:869:24: note: in expansion of macro '__safe_cmp' __builtin_choose_expr(__safe_cmp(x, y), \ ^ /kisskb/src/include/linux/kernel.h:878:19: note: in expansion of macro '__careful_cmp' #define min(x, y) __careful_cmp(x, y, <) ^ /kisskb/src/mm/nobootmem.c:104:11: note: in expansion of macro 'min' order = min(MAX_ORDER - 1UL, __ffs(start)); ^ /kisskb/src/net/ipv4/tcp_input.c: In function 'tcp_data_queue': /kisskb/src/net/ipv4/tcp_input.c:4319:49: warning: array subscript is above array bounds [-Warray-bounds] tp->selective_acks[i-1] = tp->selective_acks[i]; ^ In file included from /kisskb/src/arch/arc/include/asm/atomic.h:16:0, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/lock.h:5, from /kisskb/src/arch/arc/include/asm/bitops.h:429, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:11, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/module.h:9, from /kisskb/src/net/core/filter.c:24: /kisskb/src/net/core/filter.c: In function 'bpf_clear_redirect_map': /kisskb/src/arch/arc/include/asm/cmpxchg.h:95:29: warning: value computed is not used [-Wunused-value] #define cmpxchg(ptr, o, n) ((typeof(*(ptr)))__cmpxchg((ptr), \ ^ /kisskb/src/net/core/filter.c:3262:4: note: in expansion of macro 'cmpxchg' cmpxchg(&ri->map, map, NULL); ^ Completed OK # rm -rf /kisskb/build/linus_axs101_defconfig_arcompact # Build took: 0:01:22.945080
