   1 ## Make sure that using -g (or equivalent) on an asm file that already has
   2 ## debug-info directives in it will correctly ignore the -g and produce
   3 ## debug info corresponding to the directives in the source.
   4 ## Note gcc accepts ".file 1" after a label, although not after an opcode.
   5 ## If no other directives appear, gcc emits no debug info at all.
