/* Some of the following mnemonics might seem a little cryptic,
|
|
** especially those like F1_1a. The decision to choose these mnemo-
|
|
** nics is based on the fact that the manual `Z8000 PLZ/ASM Assembly
|
|
** Language Programming Manual' distinguishes some instruction for-
|
|
** mats and gave them names like F1.1, etc. In fact section 3.3 of
|
|
** this manual describes the instruction set and mentions with each
|
|
** instruction also the corresponding instruction format(s). So I
|
|
** sorted all instructions on their instruction format(s) resulting
|
|
** in groups named F1_1, F1_2, F2_1, etc. (Groups consisting of one
|
|
** member where named to that member). Almost all groups were so
|
|
** consistent that writing one yacc-rule per group sufficed. Only
|
|
** some groups had to be split up resulting in mnemonics like F1_1a
|
|
** and F1_1b.
