Synopsis
 _mm512_mask_max_ph(__m512h src, __mmask32 k, __m512h a, __m512h b);
Description
Compare packed half-precision (16-bit) floating-point elements in "a" and "b", and store packed maximum values in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). [max_float_note]
Operation
FOR j := 0 to 31
	IF k[j]
		dst.fp16[j] := (a.fp16[j] > b.fp16[j] ? a.fp16[j] : b.fp16[j])
	ELSE
		dst.fp16[j] := src.fp16[j]
	FI
ENDFOR
dst[MAX:512] := 0
