- * Fast bitblt macros for certain hardware. If your machine has an addressing
- * mode of small constant + register, you'll probably want this magic specific
- * code. It's 25% faster for the R2000. I haven't studied the Sparc
- * instruction set, but I suspect it also has this addressing mode. Also,
- * unrolling the loop by 32 is possibly excessive for mfb. The number of times
- * the loop is actually looped through is pretty small.
- */
-
-/*
- * WARNING: These macros make *a lot* of assumptions about
- * the environment they are invoked in. Plenty of implicit
- * arguments, lots of side effects. Don't use them casually.
