The format of the opcode table is:
- NAME OPCODE MASK { OPERANDS }
+ NAME OPCODE MASK { OPERANDS } MEMOP PROCESSOR
NAME is the name of the instruction.
OPCODE is the instruction opcode.
MASK is the opcode mask; this is used to tell the disassembler
which bits in the actual opcode must match OPCODE.
OPERANDS is the list of operands.
+ MEMOP specifies which operand (if any) is a memory operand.
+ PROCESSORS specifies which CPU(s) support the opcode.
The disassembler reads the table in order and prints the first
instruction which matches, so this table is sorted to put more
specific instructions before more general instructions. It is also
- sorted by major opcode. */

+ sorted by major opcode.
+
+ The table is also sorted by name. This is used by the assembler.
+ When parsing an instruction the assembler finds the first occurance
+ of the name of the instruciton in this table and then attempts to
+ match the instruction's arguments with description of the operands
+ associated with the entry it has just found in this table. If the
+ match fails the assembler looks at the next entry in this table.
+ If that entry has the same name as the previous entry, then it
+ tries to match the instruction against that entry and so on. This
+ is how the assembler copes with multiple, different formats of the
