AT&T compilers these days all come with a tool, call "dis", for
disassembler. that look at object files and tell you exactly what
instructions are in them.

This is neccessary because it is sometimes not possible to look at a
.s and tell exactly what instructions the assembler will produce. For
example an assembler might replace some long forms of jumps by short
forms.
