pub fn _mm_mask_fixupimm_sd(a: __m128d, k: __mmask8, b: __m128d, c: __m128i, IMM8: i32) -> __m128dFix up the lower double-precision (64-bit) floating-point elements in a and b using the lower 64-bit integer in c, store the result in the lower element of dst using writemask k (the element is copied from a when mask bit 0 is not set), and copy the upper element from b to the upper element of dst. imm8 is used to set the required flags reporting.
