_mm_broadcastb_epi8, _mm256_broadcastb_epi8

Take byte elements from the source operand and broadcast to all elements of the result vector. The corresponding Intel® AVX2 instruction is


extern __m128i _mm_broadcastb_epi8(__m128i val);
extern __m256i _mm256_broadcastb_epi8(__m128i val);
__m128i vector containing the elements to be broadcasted
Takes a byte integer in the low bits of the source operand and broadcasts to all elements of the result vector.
Returns result of the broadcast operation.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
