2021-09-22Fortran: Improve -Wmissing-include-dirs warnings [PR55534]Tobias Burnus1-1/+1
It turned out that enabling the -Wmissing-include-dirs for libcpp did output too many warnings – at least as run with -B and similar options during the GCC build and warning for internal include dirs like finclude, unlikely of relevance to for a real-world user. This patch now only warns for -I and -J by default but permits to get the full warnings including libcpp ones with -Wmissing-include-dirs. It additionally documents this in the manual. With that change, the -Wno-missing-include-dirs could be removed from libgfortran's configure and libgomp's testsuite always cflags. This reverts those bits of the previous commit r12-3722-g417ea5c02cef7f000e66d1af22b066c2c1cda047 Additionally, it turned out that all call to load_file called exit explicitly - except for the main file via gfc_init -> gfc_new_file. The latter also output a file not existing fatal error, such that two errors where printed. Now exit is called in line with the other users of load_file. Finally, when compileing with "nonexisting/file.f90", first a warning that "nonexisting" does not exist as include path was printed before the file not found error was printed. Now the directory in which the physical file is located is added silently, relying on the file-not-found diagnostic for those.
