Please rebase and move the CHANGELOG entry to 12.0.2. |
Optional argument analysis now only considers calls from live code when determining which optional arguments are unused. This prevents false positives when a function is only called from dead code. Changes: - Add pos_from to optional_arg_call to track caller binding position - Add is_live predicate to compute_optional_args_state - Two-pass solve: first compute deadness, then optional args with liveness - Add Decl.isLive helper to simplify repeated liveness checks - Update ARCHITECTURE.md to document the two-pass approach Signed-Off-By: Cristiano Calcagno <cristiano.calcagno@gmail.com>
