Question: The 68000 has special instructions for use with small literals (e.g., MOVEQ and ADDQ). Some assemblers do not acknowledge these instructions explicitly and automatically make use of them (i.e., the programmer writes ADD #1, DO and the assembler chooses the code conesponding to ADDQ #1, DO). Is this a good idea, since it permits compact instruction coding without forcing the programmer to learn about the "Q" options?
