The IC IALLU characteristics are:
Invalidate all instruction caches to Point of Unification.
AArch64 System instruction IC IALLU performs the same function as AArch32 System instruction ICIALLU.
IC IALLU is a 64-bit System instruction.
IC IALLU ignores the value in the register specified by the instruction encoding. Software does not have to write a value to the register before issuing this instruction.
Accesses to this instruction use the following encodings:
Rt | op0 | op1 | op2 | CRn | CRm |
---|---|---|---|---|---|
0b11111 | 0b01 | 0b000 | 0b000 | 0b0111 | 0b0101 |
