CLRHack: restarts

In the CLRHack compiler, restart-bind is a primitive form that manages the dynamic lifecycle of Common Lisp restarts by manipulating a thread-local stack of active restart objects. Handling of restart-bind When the compiler encounters a restart-bind form, it generates CIL code that performs the following steps: Capture Previous State: It calls Lisp.RestartControl::GetActiveRestarts() to retrieve the current list of active restarts and stores it in a frame-local variable. Construct New List: For each binding, it evaluates the restart name, handler function, and optional keyword arguments (:report-function, :interactive-function, :test-function). It then instantiates a new [LispBase]Lisp.Restart object and conses it onto the existing list. Install New State: It calls Lisp.RestartControl::SetActiveRestarts(new_list) to update the dynamic environment. Protected Execution: The body of the restart-bind is wrapped in a CIL .try block. Restoration: A finally block is emitted that restores the…
