Before the problematic revision, the files were named foo.gcda and foo.gcno.

--- Comment #2 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
'fraid the change was intentional.  Different compilations of foo.c, with
different options, now get different gcda files, instead of one stepping on the
other's toes.

You have to separate compilation and linking to get foo.gc{da,no}, or use the
"-dumpbase ''" workaround to restore prior aux output naming conventions.
