Almost. It only recognises "mov.r", not "movl.r" because the normal suffix
checking code works on the original string, so it tries to parse the
"movl.r" and can't match the ".r". The -1 in the code after the
check_suffix: label should be -3 if the ".r" was found.

Other than that it seems fine. "mov.r %esp, %ebp" works, and my other tests
I've written work too.

Note that I have applied the patch by hand because my "mail client" doesn't
work too well with inlined patches. I don't think this caused the problem
though.

Not yet, but this looks like something I'll need sooner or later anyway, so
I'll take a look at it.

Thanks again,
Stefan
