Each thread runs its own stylecheck script, outputing to {FILENAME}.stylecheck file. If that file is empty, it is deleted. Otherwise it is printed to the output and stays in the sources directory to indicate something in that file is not correct.
The file mangling and cat-ing is needed because of multithreaded nature of paralell make. (We like single file to be an block of text on the output).
New PHONY added that make styleclean clears all .stylecheck files.
New functionality added to check only single file (specifyilng the file with stylecheck extension) ie
make lib/usb/usb.c.stylecheck
BUG: if someone edit that file, .stylecheck file is not regenerated - missing dependency on the %.stylecheck rule. FIX: make styleclean stylecheck rebuild all style errors
Performance:
make stylecheck 1:43 -> 1:54 (slightly slower due to file creation)
make stylecheck -j8 1:43 -> 0:34 (Rapidly faster)
note the -j option must be specified with number, OS Windows cannot handle one thread per file.
