gas

[rkc]

(This may be a repost.  Apologies for our mailer.)
Awhile back we were using GCC with Sun's assembler.  At that time I had
written the following copy code:

   asm volatile("tstl %4;jle 1$;subqw #1,%4; 0$: movel %1 at +,%0 at +; dbf %4,0$;1$:"
      : "=a" (p_to), "=a" (p_from)
      : "0" (p_to), "1" (p_from), "d" (n_longs) );

Now we have converted to Gas (Gnu's assembler), which doesn't seem to
understand the 0$ construct.  Can someone point me to some documentation on
gas and how to create these local variables, or perhaps point me to a correct
newsgroup to mail this to.
