Nuno and I wrote a blog post about alive2:
https://blog.regehr.org/archives/1722
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:
http://volta.cs.utah.edu:8080/
this instance is temporary and availability may not be super high, we're looking for a permanent home
Thanks!
