As part of some other work I was doing looking at constant multiplies on various platforms, and that led to looking a the em68k __mulsi3 code.
Which in turn led to the following microoptimizations. Note that this is desk-checked but UNTESTED, thus the RFC nature of the patches. A bit of cleverness uses the available A0 and A1 registers to save three instruction words one memory fetch, shaving 16 cycles off the code. -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
