///
/// This file is not part of the Verilated public-facing API.
///
/// It is only for internal use; code using machine-specific intrinsics for
/// optimization should include this header rather than directly including
/// the target-specific headers. We provide macros to check for availability
/// of instruction sets, and a common mechanism to disable them.
