move-object

Purpose

Move the contents of one object-bearing register to another.

Details

Op & Format	Mnemonic / Syntax	Arguments
07 12x	move-object vA, vB	`A:` destination register (4 bits) `B:` source register (4 bits)
08 22x	move-object/from16 vAA, vBBBB	`A:` destination register (8 bits) `B:` source register (16 bits)
09 32x	move-object/16 vAAAA, vBBBB	`A:` destination register (16 bits) `B:` source register (16 bits)

Constraints

Both A and B must be legal register indices in the current stack frame.
Register vB must be defined.
Register vB must contain a reference value (which excludes the case of it being part of a register pair).

Behavior

The value of register vB is moved to register vA, that is, vA' = vB.
If register v(A-1) is the lower half of a register pair, register v(A-1)' becomes undefined.
If register v(A+1) is the upper half of a register pair, register v(A+1)' becomes undefined.

Exceptions

None.
