Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR changes ToIR to call `lowerEnumToScalarType?` with `ConstructorVal.induct` rather than the name of the constructor itself. This was an oversight in some refactoring of code in the new compiler before landing it. It should not affect runtime of compiled code (due to the extra tagging/untagging being optimized by LLVM), but it does make IR for the interpreter slightly more efficient. |
