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