Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.

This PR removes the old ElimDeadBranches pass and shifts the new one past lambda lifting. The reason for dropping the old one is its general unsoundness and the fact that we want to do refactorings on the IR part. The reason for shifting the current pass past lambda lifting, is that its analysis is imprecise in the presence of local function symbols. I experimented with the exact placement for a while and it seems like it is optimal here. Overall we observe a slight regression in the amount of C code generated, likely because we don't propagate information into lambdas before lifting them anymore. But generally measure a slight performance improvement in general. |
