__arm_cdp, __arm_cdp2

In this section:

Syntax

void __arm_cdp(__cpid coproc, __cpopcw opc1, __cpreg CRd, __cpreg CRn,
               __cpreg CRm, __cpopc opc2);

void __arm_cdp2(__cpid , __cpopw coprocopc1, __cpreg CRd, __cpreg CRn,
                __cpreg CRm, __cpopc opc2);

Parameters

`coproc`	The coprocessor number `0..15`.
`opc1`, `opc2`	Coprocessor-specific operation codes.
`CRd`, `CRn`, `CRm`	Coprocessor registers.

Description

Inserts the coprocessor-specific data operation instruction CDP or CDP2. The parameters will be encoded in the instruction and must therefore be constants.

These intrinsic functions are defined according to the Arm C Language Extensions (ACLE).

Note

These intrinsic functions cannot be used in 64-bit mode.
