pub unsafe fn _mm_mask3_fnmadd_ps(a: __m128, b: __m128, c: __m128, k: u8) -> __m128
🔬This is a nightly-only experimental API. (stdsimd)
Available on x86-64 only.
Expand description

Multiply packed single-precision (32-bit) floating-point elements in a and b, add the negated intermediate result to packed elements in c, and store the results in dst using writemask k (elements are copied from c when the corresponding mask bit is not set).
