/* The opcode table.
|
||
|
||
The format of the opcode table is:
|
||
|
||
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.
|
||
|
||
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
|
||
same instruction. */
