How is inline assembly in C/C++ translated into assembly code?

Hi,

I have a question about inline assembly. Inline assembly is usually
written in the form of
__asm__ ("code");. I want to know where in the GCC, the inline assembly
string ( "code" in __asm__()) will be translated into assembly code and
how
it happens? Is there a module in GCC for this purpose?

Thanks
