1225 // don't think .b is valid at all! I only know of .w/.l, so
1226 // this should probably be wiped). Then the code that
1227 // parses the constant and checks to see if it's between
1228 // $ffff0000 and $8000 never got triggered, so yay job
1229 // done! ...now say we want to assemble a st .prg. One of
1230 // the most widely spread optimisations is move.X expr.w,Y

1234 // access hardware registers. So I made a condition to see
1235 // if st mode or jaguar is active and apply the both or
1236 // not. One last note: this is hardcoded to get optimised
1237 // for now on ST mode, i.e. it can't generate code like
1238 // move.w $00001234,d0 - it'll always get optimised to
1239 // move.w $1234.w,d0. It's probably ok, but maybe a warning
