just a note, early PIC14 had handwritten optimizations for some multiplications before the generic multiply https://sourceforge.net/p/sdcc/code/5000/tree/trunk/sdcc/src/pic/genarith.c line 1528, genUMult8XLit_16() (For some literals this was including swap instruction) Don't know whether this helps:) Greetings, Frieder ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
