Package: regalloc2-tool (0.9.4-1 and others)

backtracking register allocator

regalloc2 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.

In addition, it contains substantial amounts of testing infrastructure (fuzzing harnesses and checkers) that does not exist in the original IonMonkey allocator.

This package contains the command-line tool regalloc2-tool which reads a bincode-encoded SerializableFunction and then runs the register allocator and checker on it.

This is a useful tool for debugging register allocation failures and to investigate cases of poor register allocation.
