This was excluded by mistake in #1; without a configuration, cargo-deny runs with a default one, and rejects a lot of things (largely due to open-source-but-not-allowlisted licenses). This `deny.toml` comes from the regalloc.rs repo. It results in one warning currently that will be resolved once #7 is.
regalloc2: another register allocator
This is a register allocator that started life as, and is about 50% still, a port of IonMonkey's backtracking register allocator to Rust. In many regards, it has been generalized, optimized, and improved since the initial port, and now supports both SSA and non-SSA use-cases.
In addition, it contains substantial amounts of testing infrastructure (fuzzing harnesses and checkers) that does not exist in the original IonMonkey allocator.
See the design overview for (much!) more detail on how the allocator works.
