pub unsafe fn _mm512_mask_i32gather_pd(src: __m512d, mask: __mmask8, offsets: __m256i, slice: *const f64, SCALE: i32) -> __m512dGather double-precision (64-bit) floating-point elements from memory using 32-bit indices. 64-bit elements are loaded from addresses starting at base_addr and offset by each 32-bit element in vindex (each index is scaled by the factor in scale). Gathered elements are merged into dst using writemask k (elements are copied from src when the corresponding mask bit is not set). scale should be 1, 2, 4 or 8.
