Masahiro Yamada 585d32f9b0 gen_compile_commands: prune some directories ... If directories are passed to gen_compile_commands.py, os.walk() traverses all the subdirectories to search for .cmd files, but we know some of them are not worth traversing. Use the 'topdown' parameter of os.walk to prune them. Documentation about the 'topdown' option of os.walk: When topdown is True, the caller can modify the dirnames list in-place (perhaps using del or slice assignment), and walk() will only recurse into the subdirectories whose names remain in dirnames; this can be used to prune the search, impose a specific order of visiting, or even to inform walk() about directories the caller creates or renames before it resumes walk() again. 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 6ca4c6d259 ("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.
