Intrinsics for All Intel® Architectures

Most of the intrinsics documented in this section function for all supported Intel® architectures.

Some of the intrinsics documented in this section function across a subset of Intel® architectures.

Integer Arithmetic Intrinsics
Floating-point Intrinsics
String and Block Copy Intrinsics
Miscellaneous Intrinsics
_may_i_use_cpu_feature
Queries the processor dynamically at the source level (this intrinsic does not perform a vendor check) to determine if processor-specific features are available.
_allow_cpu_features
Tells the compiler that the code region may be targeted for processors with the specified features. The compiler may then generate optimized code for the specified features.
