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 # Acked-by: Nathan Chancellor # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 585d32f9b0532ca2407943edec163c23191de488 # < make -s -j 32 ARCH=mips O=/kisskb/build/kbuild_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 32 ARCH=mips O=/kisskb/build/kbuild_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 32 ARCH=mips O=/kisskb/build/kbuild_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 32 ARCH=mips O=/kisskb/build/kbuild_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c: In function 'is1_entry_set': /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: missing braces around initializer [-Wmissing-braces] struct ocelot_vcap_u16 etype = {0}; ^ /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: (near initialization for 'etype.value') [-Wmissing-braces] FIT description: Linux 5.11.0-rc7-g585d32f9b053 Created: Wed Feb 17 01:28:15 2021 Image 0 (kernel@0) Description: Linux 5.11.0-rc7-g585d32f9b053 Created: Wed Feb 17 01:28:15 2021 Type: Kernel Image Compression: gzip compressed Data Size: 5220603 Bytes = 5098.25 KiB = 4.98 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x8098f198 Hash algo: sha1 Hash value: d378bb1b2cee477ae90bd808ac37df3bfeec4c86 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Wed Feb 17 01:28:15 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Wed Feb 17 01:28:15 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@ocelot_pcb123) Description: MSCC Ocelot PCB123 Device Tree Created: Wed Feb 17 01:28:15 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 4659 Bytes = 4.55 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 5bcb6e4f21e8e5372544aa130b3bd097355a9050 Image 4 (fdt@ocelot_pcb120) Description: MSCC Ocelot PCB120 Device Tree Created: Wed Feb 17 01:28:15 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 5418 Bytes = 5.29 KiB = 0.01 MiB Architecture: MIPS Hash algo: sha1 Hash value: 93d882f2009a217e0fa9dab94788535ed2be8476 Image 5 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Wed Feb 17 01:28:15 2021 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@ocelot_pcb123) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb123 Configuration 4 (conf@ocelot_pcb120) Description: Ocelot Linux kernel Kernel: kernel@0 FDT: fdt@ocelot_pcb120 Configuration 5 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/kbuild_mips-defconfig_mips-gcc4.9 # Build took: 0:02:00.596656
