pub const fn _mm256_mask_shldv_epi32(a: __m256i, k: __mmask8, b: __m256i, c: __m256i) -> __m256iConcatenate packed 32-bit integers in a and b producing an intermediate 64-bit result. Shift the result left by the amount specified in the corresponding element of c, and store the upper 32-bits in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
