SYSL

System instruction with result. For more information, see Op0 equals 0b01, cache maintenance, TLB maintenance, and address translation instructions for the encodings of System instructions.

This instruction is used by the aliases GCSPOPM, and GCSSS2.

Assembler Symbols

<Xt>

Is the 64-bit name of the general-purpose destination register, encoded in the "Rt" field.
<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.

Alias Conditions

Alias Is preferred when
GCSPOPM op1 == '011' && CRn == '0111' && CRm == '0111' && op2 == '001'
GCSSS2 op1 == '011' && CRn == '0111' && CRm == '0111' && op2 == '011'

Operation

// No architecturally defined instructions here.
AArch64.SysInstrWithResult(1, sys_op1, sys_crn, sys_crm, sys_op2, t);
