Using GCC to produce readable assembly?

I was wondering how to use GCC on my C source file to dump a mnemonic version of the machine code so I could see what my code was being compiled into. You can do this with Java but I haven't been able to find a way with GCC.

I am trying to re-write a C method in assembly and seeing how GCC does it would be a big help.

assembly gcc c

use -Wa,-adhln as option on gcc or g++ to produce a listing output to stdout.

-Wa,... is for command line options for the assembler part (execute in gcc/g++ after C/++ compilation). It invokes as internally (as.exe in Windows). See

>as --help

as command line to see more help for the assembler tool inside gcc
