1.27.0 · source · pub unsafe fn _mm256_testz_pd(a: __m256d, b: __m256d) -> i32
Available on (x86 or x86-64) and target feature
avx
and x86-64 only.Expand description
Computes the bitwise AND of 256 bits (representing double-precision (64-bit)
floating-point elements) in a
and b
, producing an intermediate 256-bit
value, and set ZF
to 1 if the sign bit of each 64-bit element in the
intermediate value is zero, otherwise set ZF
to 0. Compute the bitwise
NOT of a
and then AND with b
, producing an intermediate value, and set
CF
to 1 if the sign bit of each 64-bit element in the intermediate value
is zero, otherwise set CF
to 0. Return the ZF
value.
