Working group sync


  • const propagation (by Wesley Wiser) on mir opt level 2

    • some great compile-time speedups due to llvm and later MIR passes having less to do
    • Perf (active PR) has some regressions (up to 4% though)
  • rewrite loads of recursive Place algorithms imperatively (by Santiago Pastorino)

  • WIP PR by Santiago Pastorino for making Place a struct instead of an enum (preliminary work for making projections a slice instead of a recursive enum)
