Synthetic opcodes are composed of a 16 bit opcode followed by
|
|
operands. All operands will be aligned appropriately. Operands taking 16 or
|
|
fewer bits in the 68k instruction stream will NEVER be extended to 32 bits
|
|
in the synthetic stream.
|
|
|
|
If this instruction ends a block and has one or more known destination
|
|
blocks, the synthetic opcode is immediately followed by pointers to
|
|
the synthetic code in those blocks.
|
|
|
|
Next come any 32 bit operands not mentioned in the 68k description
|
|
file (eg, return addresses for jsrs).
|
|
|
|
Next come all 32 bit operands explicitly mentioned in the 68k
|
|
description file, in "field number" order (eg, $2.u precedes $4.s, etc.)
|
|
|
|
Finally we have all 16 bit operands, also in "field number" order.
