🔬This is a nightly-only experimental API. (
stdarch_x86_avx512
#111137)Available on (x86 or x86-64) and target feature
avx512ifma,avx512vl
and x86-64 only.Expand description
Multiply packed unsigned 52-bit integers in each 64-bit element of
b
and c
to form a 104-bit intermediate result. Add the high 52-bit
unsigned integer from the intermediate result with the
corresponding unsigned 64-bit integer in a
, and store the
results in dst
using writemask k
(elements are zeroed
out when the corresponding mask bit is not set).
