pub unsafe fn _mm256_reduce_ph(a: __m256h, const IMM8: i32) -> __m256h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature 
avx512fp16,avx512vl and x86 only.Expand description
Extract the reduced argument of packed half-precision (16-bit) floating-point elements in a by the number of bits specified by imm8, and store the results in 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
