Synopsis
_mm512_mask_reduce_gmin_pd(__mmask8 k, __m512d a);
Description
Determines the minimum element of the packed double-precision (64-bit) floating-point elements stored in "a" and stores the result in "dst". Bitmask "k" is used to exclude certain elements (elements are ignored when the corresponding mask bit is not set).
Operation
min := a[63:0]
FOR j := 1 to 7
i := j*64
IF k[j]
CONTINUE
ELSE
dst := FpMin(min, a[i+63:i])
FI
ENDFOR
dst := min
