i hope i'm not missing the point of your mail.

you want to make some part of you program with assembly, and
also want to optimise it with MMX instruction set, right?

you can do it with any version of GCC if you write assembly code
by yourself.

let's say you got main.c and func.c where func.c has function foo() 
which need to be optimized.

$ gcc -O9 -mpentium -S func.c

gives you assembly code func.s.  make some chage. save it.
(or you can just write entire func.s by yourself, of cause)
then,

$ gcc -c func.s
$ gcc -c main.c
$ gcc main.o func.o

have fun with a.out
