Function simd_relaxed_fma

pub unsafe extern "rust-intrinsic" fn simd_relaxed_fma<T>(
    x: T,
    y: T,
    z: T,
) -> T

🔬This is a nightly-only experimental API. (core_intrinsics)

Computes (x*y) + z for each element, non-deterministically executing either a fused multiply-add or two operations with rounding of the intermediate result.

The operation is fused if the code generator determines that target instruction set has support for a fused operation, and that the fused operation is more efficient than the equivalent, separate pair of mul and add instructions. It is unspecified whether or not a fused operation is selected, and that may depend on optimization level and context, for example. It may even be the case that some SIMD lanes get fused and others do not.

T must be a vector of floats.
