The removed # version check just so happened to prevent __compiletime_error() from # being defined with clang because it pretends to be GCC 4.2.1 for # compatibility but the error attribute was not added to clang until # 14.0.0. # # Commit 815f0ddb346c ("include/linux/compiler.h: make compiler-.h # mutually exclusive") and commit a3f8a30f3f00 ("Compiler Attributes: use # feature checks instead of version checks") refactored the handling of # attributes in the main kernel to avoid situations like this but that # refactoring has never been done for the tools directory. # # Refactoring is a rather large undertaking and this has never been an # issue before so instead, just guard the definition of # __compiletime_error() with __has_attribute() so that there are no more # errors. # # Fixes: 4e59869aa655 ("compiler-gcc.h: drop checks for older GCC versions") # Signed-off-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 d0ee23f9d78be5531c4b055ea424ed0b489dfe9b # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allnoconfig # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allnoconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1515:2: warning: #warning syscall clone3 not implemented [-Wcpp] kernel: arch/sparc/boot/image is ready /kisskb/src/arch/sparc/boot/Makefile:26: FORCE prerequisite is missing kernel: arch/sparc/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_sparc64-allnoconfig_sparc64 # Build took: 0:00:27.752564
