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/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < git log --format=%s --max-count=1 815f0ddb346c196018d4d8f8f55c12b83da1de3f # < make -s -j 10 ARCH=arm O=/kisskb/build/linus_tct_hammer_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- tct_hammer_defconfig # make -s -j 10 ARCH=arm O=/kisskb/build/linus_tct_hammer_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here Completed OK # rm -rf /kisskb/build/linus_tct_hammer_defconfig_arm # Build took: 0:00:43.472143
