1.27.0 · source · pub unsafe fn _mm_testc_ps(a: __m128, b: __m128) -> i32
Available on (x86 or x86-64) and target feature
avx
and x86 only.Expand description
Computes the bitwise AND of 128 bits (representing single-precision (32-bit)
floating-point elements) in a
and b
, producing an intermediate 128-bit
value, and set ZF
to 1 if the sign bit of each 32-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 32-bit element in the intermediate value
is zero, otherwise set CF
to 0. Return the CF
value.
