TSK3000A Generic Instruction - XOR
Frozen Content
Instruction: Bitwise Logical Exclusive OR
| Assembler Format | Example | Translates to... |
|---|---|---|
xor rC, rB | xor $3, $4 | xor rC, rC, rB (with rA = rC) |
xor rC, rA, IMM32 | xor $3, $2, 0x12345678 | see note 2 |
xor rC, IMM32 (see note 1) | xor $3, 0x12345678 | see note 2 |
Notes
- This format can also be written as: xor rC, rC, IMM32 (with rA = rC)
- If the signed IMM32 operand fits into an unsigned 16-bit operand, then these two macro formats translate into single XORI machine instructions:
xor rC, rA, IMM32
translates to.....
xori rC, rA, IMM16
xor rC, IMM32
translates to.....
xori rC, rC, IMM16 (with rA = rC)
If the IMM32 operand does not fit, or has an unknown value, then these two macro formats translate to:
li $at, IMM32
xor rC, rA, $at
