I came across this assembly instruction in x86util.asm:

movdqa m%5, %10

Is there a register that starts with 'm' ? Couldn't find a reference to it in the instruction reference manual.

I am still confused !

MMX registers are referenced as mm0 etc
but what does m0 stand for ? A memory location ? If so, is it there in the manual ?
