ARM base instruction -- ic
Instruction Cache operation.
指令缓存操作。
This instruction is an alias of the SYS instruction. This means that:
• The encodings in this description are named to match the encodings of SYS.
• The description of SYS gives the operational pseudocode for this instruction.
此指令是SYS指令的别名。这意味着：
•本说明中的编码名称与SYS的编码相匹配。
•SYS的描述给出了此指令的操作伪代码。
System variant
IC <ic_op>{, <Xt>}
is equivalent to
SYS #<op1>, C7, <Cm>, #<op2>{, <Xt>}
and is the preferred disassembly when SysOp(op1,'0111',CRm,op2) == Sys_IC.
