Where the existing ports need to emit this information, they use
FILE_ASM_OP - usually defined to something like file or .file,
or better, output_file_directive .
output_file_directive uses ASM_OUTPUT_MAIN_SOURCE_FILENAME or
ASM_OUTPUT_SOURCE_FILENAME, if defined.
output_file_directive can be called from ASM_FILE_START; e.g. look at
config/svr4.h .
