Modifying # dirnames when topdown is False has no effect on the behavior of # the walk, because in bottom-up mode the directories in dirnames # are generated before dirpath itself is generated. # # This commit prunes four directories, .git, Documentation, include, and # tools. # # The first three do not contain any C files, so skipping them makes this # script work slightly faster. My main motivation is the last one, tools/ # directory. # # Commit 6ca4c6d25949 ("gen_compile_commands: do not support .cmd files # under tools/ directory") stopped supporting the tools/ directory. # The current code no longer picks up .cmd files from the tools/ # directory. # # If you run: # # ./scripts/clang-tools/gen_compile_commands.py --log_level=INFO # # then, you will see several "File ... not found" log messages. # # This is expected, and I do not want to support the tools/ directory. # However, without an explicit comment "do not support tools/", somebody # might try to get it back. Clarify this. # # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # Acked-by: Nathan Chancellor <nathan@kernel.org> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 585d32f9b0532ca2407943edec163c23191de488 # < make -s -j 32 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # < make -s -j 32 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 32 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 32 ARCH=arm64 O=/kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:25: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:33: LSE atomics not supported by binutils Completed OK # rm -rf /kisskb/build/kbuild_arm64-defconfig_arm64-gcc5.4 # Build took: 0:07:00.478404
