Function _mm_reduce_round_sd

pub unsafe fn _mm_reduce_round_sd(
    a: __m128d,
    b: __m128d,
    const IMM8: i32,
    const SAE: i32,
) -> __m128d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512dq and x86-64 only.

Extract the reduced argument of the lower double-precision (64-bit) floating-point element in b by the number of bits specified by imm8, store the result in the lower element of dst, and copy the upper element from a to the upper element of dst. Rounding is done according to the imm8 parameter, which can be one of:

• _MM_FROUND_TO_NEAREST_INT : round to nearest
• _MM_FROUND_TO_NEG_INF : round down
• _MM_FROUND_TO_POS_INF : round up
• _MM_FROUND_TO_ZERO : truncate
• _MM_FROUND_CUR_DIRECTION : use MXCSR.RC - see _MM_SET_ROUNDING_MODE

Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
