Add << prefix to force 5 bit offsets in indexed modes Rounding out the compliment of operand size prefixes, we now have "<<" to mean "force 5 bits". According to Steve Bjork, this was the "official" way to do this since 1980. However, I have no official Motorola source for that. It does suggest that the choice of "<<" is consistent with other (historical) assemblers, though. Either way, it seems the most logical choice while avoiding any conflicts with legal source code, so "<<" it is.
