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:
op0 | op1 | CRn | CRm | op2 | Rt |
---|---|---|---|---|---|
0b01 | 0b000 | 0b0111 | 0b0101 | 0b000 | 0b11111 |
if PSTATE.EL == EL0 then UNDEFINED; elsif PSTATE.EL == EL1 then if EL2Enabled() && !ELUsingAArch32(EL2) && HCR_EL2.TPU == '1' then AArch64.SystemAccessTrap(EL2, 0x18); elsif EL2Enabled() && !ELUsingAArch32(EL2) && HCR_EL2.TOCU == '1' then AArch64.SystemAccessTrap(EL2, 0x18); elsif EL2Enabled() && !ELUsingAArch32(EL2) && HCR_EL2.FB == '1' then IC_IALLUIS(); else IC_IALLU(); elsif PSTATE.EL == EL2 then IC_IALLU(); elsif PSTATE.EL == EL3 then IC_IALLU();
