Luciano, the question is a bit unclear. First, MMIX is strictly
speaking not a language, but a microprocessor architeture. Most
likely, you do not want to be writing in the binary code that is the
machine code language of MMIX.
If you're using the mmix-gcc and wish to mix assembly to C code, then
that's completely standard. You can either inline assembly with the
usual asm() syntax, eg. asm("ADDI $2,$5,8") or write an complete
assembly file and with with that.
If you wish to instrument the simulator (as John implies), then it is
not that hard at all to modify the MMIX simulator. However, if you need
access to all of MMIX (notably the priviledge instructions) then you
need to modify the pipeline simulator MMMIX, which is a non-trivial
