/* Function Naming Conventions
|
|
* The naming convention of SSE intrinsics is straightforward. A generic SSE
|
|
* intrinsic function is given as follows:
|
|
* _mm_<name>_<data_type>
|
|
*
|
|
* The parts of this format are given as follows:
|
|
* 1. <name> describes the operation performed by the intrinsic
|
|
* 2. <data_type> identifies the data type of the function's primary arguments
|
|
*
|
|
* This last part, <data_type>, is a little complicated. It identifies the
|
|
* content of the input values, and can be set to any of the following values:
|
|
* + ps - vectors contain floats (ps stands for packed single-precision)
|
|
* + pd - vectors cantain doubles (pd stands for packed double-precision)
|
|
* + epi8/epi16/epi32/epi64 - vectors contain 8-bit/16-bit/32-bit/64-bit
|
|
* signed integers
|
|
* + epu8/epu16/epu32/epu64 - vectors contain 8-bit/16-bit/32-bit/64-bit
|
|
* unsigned integers
|
|
* + si128 - unspecified 128-bit vector or 256-bit vector
|
|
* + m128/m128i/m128d - identifies input vector types when they are different
|
|
* than the type of the returned vector
|
|
*
|
|
* For example, _mm_setzero_ps. The _mm implies that the function returns
|
|
* a 128-bit vector. The _ps at the end implies that the argument vectors
|
|
* contain floats.
|
|
*
|
|
* A complete example: Byte Shuffle - pshufb (_mm_shuffle_epi8)
|
|
* // Set packed 16-bit integers. 128 bits, 8 short, per 16 bits
|
|
* __m128i v_in = _mm_setr_epi16(1, 2, 3, 4, 5, 6, 7, 8);
|
|
* // Set packed 8-bit integers
|
|
* // 128 bits, 16 chars, per 8 bits
|
|
* __m128i v_perm = _mm_setr_epi8(1, 0, 2, 3, 8, 9, 10, 11,
|
|
* 4, 5, 12, 13, 6, 7, 14, 15);
|
|
* // Shuffle packed 8-bit integers
|
|
* __m128i v_out = _mm_shuffle_epi8(v_in, v_perm); // pshufb
