GIC

Generic Interrupt Controller

This instruction manages interrupts when FEAT_GCIE is implemented.

This is an alias of SYS. This means:

System class

(FEAT_GCIE)

313029282726252423222120191817161514131211109876543210
1101010100001op11100IN {0001, 0010}op2Rt
LCRnCRm

Encoding

GIC <gic_op>, <Xt>

is equivalent to

SYS #<op1>, C12, <Cm>, #<op2>{, <Xt>}

and is the preferred disassembly when SysOp(op1, '1100', CRm, op2) == Sys_GIC.

Assembler Symbols
