[llvm-dev] Interprocedural register allocation. Status?

[Jon Chesterfield via llvm-dev]

There was a GSoC project in 2016, final report at
https://docs.google.com/document/d/1v-R7gB7Or4bPn0LW7d-yb1yla8jK3DVmTJNFVNYNu6k

Google doesn't show a lot of activity since. Has anyone taken this work
further / put it near production? I'm interested in removing register
spills around functions that are known to not clobber said registers.

Thanks!

Jon
