Intrinsics are C or C++ pseudo-function calls that the compiler replaces with the appropriate SIMD instructions. These intrinsics let you use the data types and operations available in the SIMD implementation, while allowing the compiler to handle instruction scheduling and register allocation.

#ifdef __ARM_FEATURE_SVE
#include <arm_sve.h>
#endif /* __ARM_FEATURE_SVE */ 

// All functions and types that are defined in the header file have the prefix sv, to reduce the chance of collisions with other extensions.

!Docs
Common situations where SVE types might be used include:

As the type of an object with automatic storage duration.
As a function parameter or return type.
As the type in a (type) {value} compound literal.
As the target of a pointer or reference type.
As a template type argument.

!Docs reference
To enable only the base SVE2 instructions, use the +sve2 option with the armclang -march or -mcpu options. To enable additional optional SVE2 instructions, use the following armclang options:

+sve2-aes to enable scalable vector forms of AESD, AESE, AESIMC, AESMC, PMULLB, and PMULLT instructions.
+sve2-bitperm to enable the BDEP, BEXT, and BGRP instructions.
+sve2-sha3 to enable scalable vector forms of the RAX1 instruction.
+sve2-sm4 to enable scalable vector forms of SM4E and SM4EKEY instructions.
You can use one or more of these options. Each option also implies +sve2. For example, +sve2-aes+sve2-bitperm+sve2-sha3+sve2-sm4 enables all base and optional instructions. For clarity, you can include +sve2 if necessary.

Valid values for **ARCH** are the normal iOS architecture names such as armv7, armv7s, arm64, and i386 and x86_64 for the simulator. Another settable iOS specific parameter is SDK_MIN, specifying the minimum deployment target for the built library. For other details on building using make on the command line, see 'For All Platforms' below.
