Sorry, the FAQ failed to mention that you need the -g switch together
with all the rest.  Add -g, and it will work.

Also note that it's -Wa, capital W.  The full command should be like
this:

   gcc -c -g -Wa,-a,-ad foo.c >foo.lst

> Can we see assembler output?

What do you mean by ``assembler output''?  The assembler outputs
machine instructions; how do you want to see them?

If you mean you want to disassemble the produced code, either a
"disassemble" command in GDB or the --disassemble option of the
`objdump' utility will do what you want.  But that would just show
you the same assembly that "gcc -S" produces.  If you want to see the
disassembly in the Intel syntax, type "set disassembly-flavor intel"
in GDB before disassemblying.

> Another thing : in menu of GCC there isn't "extended asm" (Faq 18.2).

Please type exactly what the FAQ tells:

       info gcc "C Extensions" "Extended Asm"

and you will land on the correct spot.  Alternatively, once you are
inside the GCC manual, type "g Extended Asm" and hit [Enter].
