In this particular case, I wanted to look at it for two reasons:

1)  To determine which functions were being inlined.

2)  To identify errant calls to printf and puts.  When compiled to run in
background mode, my program should send all messages to the log rather than
stdout/stderr, so calls to printf/puts that the compiler doesn't discard as
unreachable represent program bugs.

Gcc has had the -S option for essentially forever, and I've probably used it
more times and for more reasons than I can remember at this point.
