stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature
avx512fp16 and x86-64 only.Expand description
Multiply the lower complex numbers in a and b, accumulate to the lower complex number in c, and
store the result in the lower elements of dst using writemask k (elements are copied from c when
mask bit 0 is not set), and copy the upper 6 packed elements from a to the upper elements of dst.
Each complex number is composed of two adjacent half-precision (16-bit) floating-point elements,
which defines the complex number complex = vec.fp16[0] + i * vec.fp16[1].
Rounding is done according to the rounding parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT|_MM_FROUND_NO_EXC: round to nearest and suppress exceptions_MM_FROUND_TO_NEG_INF|_MM_FROUND_NO_EXC: round down and suppress exceptions_MM_FROUND_TO_POS_INF|_MM_FROUND_NO_EXC: round up and suppress exceptions_MM_FROUND_TO_ZERO|_MM_FROUND_NO_EXC: truncate and suppress exceptions_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
