Feature Flags (Cargo)
- `mir_typeop_poc`: enable TypeOp PoC mapping (builder emits TypeOp instead of TypeCheck/Cast)
- `mir_refbarrier_unify_poc`: enable WeakRef/Barrier PoC mapping (builder emits unified ops)
- Deprecated flags (unified by default):
- `mir_typeop_poc`: no-op now. Builder always emits `TypeOp(Check/Cast)` instead of legacy `TypeCheck/Cast`。
- `mir_refbarrier_unify_poc`: no-op now. Builder always emits `WeakRef/Barrier` instead of legacy `WeakNew/WeakLoad/BarrierRead/Write`。
- Optimizer has a Pass 0 that normalizes any残存の旧命令 → 統合命令（安全ネット）。
Status (2025-08-23)
