Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
Makes the LLVM triple of the current platform available to Lean code towards a solution for #2754. Defaults to the empty string if the compiler is not clang, which can introduce some divergence between CI and local builds but should not be noticeable in most cases and is not really possible to avoid. |
