- // to mask off the upper bits depending on length (note: I
- // don't think .b is valid at all! I only know of .w/.l, so
- // this should probably be wiped). Then the code that
- // parses the constant and checks to see if it's between
- // $ffff0000 and $8000 never got triggered, so yay job
- // done! ...now say we want to assemble a st .prg. One of
- // the most widely spread optimisations is move.X expr.w,Y
- // (or vice versa, or both, anyway...) to access hardware
- // registers (which are mapped to $fxxxxx). This botchy
- // thing would create "hilarious" code while trying to
- // access hardware registers. So I made a condition to see
- // if st mode or jaguar is active and apply the both or
- // not. One last note: this is hardcoded to get optimised
- // for now on ST mode, i.e. it can't generate code like
- // move.w $00001234,d0 - it'll always get optimised to
- // move.w $1234.w,d0. It's probably ok, but maybe a warning
- // should be emitted? Or maybe finding a way to make it not
