Macro Functions

The macro function intrinsics listed here are designed for the Intel® Pentium® 4 processor with Streaming SIMD Extensions 3 (Intel® SSE3).

The prototypes for these intrinsics are in the pmmintrin.h header file.

_MM_SET_DENORMALS_ZERO_MODE

_MM_SET_DENORMALS_ZERO_MODE(x);

Macro arguments: either _MM_DENORMALS_ZERO_ON, _MM_DENORMALS_ZERO_OFF.

This macro causes "denormals are zero" mode to be turned ON or OFF by setting the appropriate bit of the control register.

_MM_GET_DENORMALS_ZERO_MODE

_MM_GET_DENORMALS_ZERO_MODE();

No arguments.

This macro returns the current value of the denormals are zero mode bit of the control register.
