Nuno and I wrote a blog post about alive2:

The tl;dr is:

- alive2 works directly on LLVM IR, there is no need to rewrite optimizations in a DSL

- alive2 handles memory operations and vectors and generally has quite a lot more coverage of LLVM features than alive did (coverage is definitely not complete, however)

- alive2 is available on a Compiler Explorer instance:

this instance is temporary and availability may not be super high, we're looking for a permanent home
