57 * On machines that have FMA as a single instruction, this will generally
58 * improve precision without significant performance implications.
59 *
60 * Without a single instruction, performance has been found to be reduced 2-3x
61 * on Intel CPUs, and up to 30x for WASM.
62 *
63 * If unspecified, defaults to using FMA if hardware support is available.
64 * The default should be used in most cases to ensure consistency between
65 * vectorized and non-vectorized paths.
