Date: Mon,  7 Nov 2022 16:36:55 +0000 (GMT)	[thread overview]

    Fix NULL filename handling
    
    The previous commit introduced a regression as some Ada tests end up passing
    NULL as the filename to remap_filename.  Handle this as before to fix them.
    
    gcc/
            * file-prefix-map.cc (remap_filename): Handle NULL filenames.
