Detailed Description

template<typename Type>
struct dsp::SIMDRegister< Type >

A wrapper around the platform's native SIMD register type.

This class is only availabe on SIMD machines. Use JUCE_USE_SIMD to query if SIMD is avaialble for your system.

SIMDRegister<Type> is a templated class representing the native vectorized version of FloatingType. SIMDRegister supports all numerical primitive types and std:complex<float> and std::complex<double> supports and most operations of the corresponding primitive type. Additionally, SIMDRegister can be accessed like an array to extract the individual elements.

If you are using SIMDRegister as a pointer, then you must ensure that the memory is suffeciently aligned for SIMD vector operations. Failing to do so will result in crashes or very slow code. Use SIMDRegister::isSIMDAligned to query if a pointer is suffeciently aligned for SIMD vector operations.

Note that using SIMDRegister without enabling optimizations will result in code with very poor performance.
