Function core::arch::x86_64::_mm256_testz_pd 1.27.0[−][src]
pub unsafe fn _mm256_testz_pd(a: __m256d, b: __m256d) -> i32
This is supported on x86-64 and target feature
avx only.Compute 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.
