Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR improves join point finding in the compiler through two means: 1. We now handle situations where a function `f` can only become a join point when a function `g` becomes a join point as well correctly. 2. We introduce a second join point finding pass after specialisation and before the following simplification pass, as the specialiser might have introduced new join point opportunities for the simplifier to exploit. Notably in the code from #10995 we now correctly detect the missing join point which required both of these changes to be made. Closes: #10995 |
