_mm256_sll_epi16/32/64
Logical shift of word/doubleword/quadword elements to left according to specified number. The corresponding Intel® AVX2 instruction is VPSLLW, VPSLLD, or VPSLLQ.
Syntax
extern __m256i _mm256_sll_epi16(__m256i s1, __m128i count); |
extern __m256i _mm256_sll_epi32(__m256i s1, __m128i count); |
extern __m256i _mm256_sll_epi64(__m256i s1, __m128i count); |
Arguments
s1 |
integer source vector used for the operation |
count |
128-bit memory location used for the operation |
Description
Performs logical shift of bits in the individual data elements (16-bit word, 32-bit doubleword, or 64-bit quadword) in source vector s1 to the left by the number of bits specified in count. The empty low-order bytes are cleared (set to all '0'). If the value specified by count is greater than 15/31/63 (depending on the intrinsic being used), the destination vector is set to all '0'.
The count argument is a 128-bit memory location. Note that only the first 64-bits of a 128-bit count operand are checked to compute the count.
Returns
Result of the left-shift operation.
