KORB
Performs a bitwise logical XOR operation between the source operand and the destination operand, storing the result in the destination. The operation is performed on the least significant 8 bits of the operands.
The following table covers what the source and destinations can be:
| source | destination(s) |
|---|---|
| r8 | r8 |
| m1 | r8 |
| imm | r8 |
| r8 | m1 |
| m1 | m1 |
| imm | m1 |
DO NOT support LOCK
This instruction is available in 64-bit mode and compatibility mode. It operates specifically on 8-bit registers or memory locations.
The destination operand MUST be an 8-bit register or memory location to avoid size mismatch. Using a larger register as a destination for KORB will result in an assembly error or unexpected behavior if manually encoded.
