To tell the compiler to produce assembly language output, pass the 
`-S' switch (note that it's a capital letter):

    gcc -S foo.c

produces a file `foo.s' containing the assembly language output of 
the compiler.

To assemble and link assembly language code you just pass it as if it 
were C source code:

    gcc -c foo.s

would assemble `foo.s' to produce `foo.o', while:

    gcc -o foo.exe foo.s

would assemble `foo.s' and link it to produce an executabe file, 
`foo.exe'.

You probably normally want to use a capital S in the extension of 
assembly language source code, i.e.:

    gcc -o foo.exe foo.S

That causes it to be preprocessed before being passed to the 
assembler, which means you can use preprocessor directives like 
#include, #define, etc, and also comments (/*...*/ or //...eol) in 
your assembly language source code.
