//! This module exposes private items in mmtk-core for testing and benchmarking. They must not be
//! used in production.
//!
//! # Notes on inlining
//!
//! In mmtk-core, we refrain from inserting inlining hints manually.  But we use `#[inline(always)]`
//! in this module explicitly because the functions here are simple wrappers of private functions,
//! and the compiler usually fails to make the right decision given that those functions are not
//! used often, and we don't compile the benchmarks using feedback-directed optimizations.
