| <op1> |
Is a 3-bit unsigned immediate, in the range 0 to 7, encoded in the "op1" field. |
| <Cn> |
Is a name 'Cn', with 'n' in the range 0 to 15, encoded in the "CRn" field. |
| <Cm> |
Is a name 'Cm', with 'm' in the range 0 to 15, encoded in the "CRm" field. |
| <op2> |
Is a 3-bit unsigned immediate, in the range 0 to 7, encoded in the "op2" field. |
| <Xt1> |
Is the 64-bit name of the first optional general-purpose source register, defaulting to '11111', encoded in the "Rt" field. |
| <Xt2> |
Is the 64-bit name of the second optional general-purpose source register, defaulting to '11111', encoded as "Rt" +1. Defaults to '11111' if "Rt" = '11111'. |
| Alias | Is preferred when |
|---|---|
| TLBIP | CRn IN {'100x'} && SysOp128(op1, CRn, CRm, op2) == Sys_TLBIP |
