Intrinsic Functions for Math Support

The following table lists the math intrinsic functions. See Modulo Addressing Intrinsic Functions for explanations of the remaining intrinsic functions.

For the latest information about intrinsic functions, refer to file intrinsics_56800E.h.

Note: Intrinsics for integers contain int in the name. Intrinsics for long long support contain LL in the name.

Note: To use long long intrinsics, you must include the instrinsics_LL_56800E.h file. Other intrinsics reside in intrinsics_56800E.h.

Note: Intrinsics library functions of the 56800EX instructions inline assembly support reside in the intrinsics_56800EX.h in the MSL directory tree. The existing -V3 compiler option is used to enable this inline assembly support for 56800EX instructions. To view intrinsics library functions of the 56800EX instructions, see Table 2.
