http://www.delorie.com/djgpp/v2faq/faq8_20.html says:
Use the -S (note: capital S) switch to GCC, and it will emit the
assembly code to a file with a .s extension. For example, the
following command:
gcc -O2 -S -c foo.c
will leave the generated assembly code on the file foo.s.
If you want to see the C code together with the assembly it was
converted to, use a command line like this:
gcc -c -g -Wa,-a,-ad [other GCC options] foo.c > foo.lst
which will output the combined C/assembly listing to the file foo.lst.
