Right now GCC names the GCNO files '-.gcno'. With your patch they get put into a specified directory. But, unless I am prepared to create over 16,000 directories each to hold just one file (I'm not), it is not sufficient. What I want to do -- unless it is going to create problems -- is to place the notes files alongside the object files. The files foo.o and foo.gcno would be in the same directory.
