Can anyone explain how to use inline MMX assembly? 

I can not find any documentation from the pgcc site, except a mention in
FAQ that it supports it.

Reading sources (i386.h) it appears that the MMX register class character
is "x". Correct? Now how do I use it? Input long long ints or what?

A short example piece of code would be excellent, or a pointer to some
documentation.

Is it possible to instruct pgcc so that it accepts inline MMX assembly
with MMX register constraints, but does not specifically generate MMX code
(except that required to load the registers)? This is because the MMX code
generation seems not to work very well (as I described in my previous
mail).
