6.1 __arm_cdp, __arm_cdp2 Intrinsic Function
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).
Suggested Replacement
__builtin_arm_cdp
__builtin_arm_cdp2
Caveats
None.
Examples
Consider migrating IAR code such
as:
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);
void __builtin_arm_cdp(__cpid coproc, __cpopcw opc1, __cpreg CRd, __cpreg CRn, __cpreg CRm, __cpopc opc2);
void __builtin_arm_cdp2(__cpid , __cpopw coprocopc1, __cpreg CRd, __cpreg CRn, __cpreg CRm, __cpopc opc2);
