Catch handlers are called with a pointer to the handler itself as the first
argument and a pointer to the parent function's stack frame as the second
-argument. The catch handler uses the `llvm.recoverframe
-<LangRef.html#llvm-frameallocate-and-llvm-framerecover-intrinsics>`_ to get a
+argument. The catch handler uses the `llvm.localrecover
+<LangRef.html#llvm-localescape-and-llvm-localrecover-intrinsics>`_ to get a
pointer to a frame allocation block that is created in the parent frame using
-the `llvm.allocateframe

The ``WinEHPrepare`` pass will have created a structure definition for the
contents of this block. The first two members of the structure will always be

A code of ``i32 1`` indicates a catch action, which expects three additional
arguments. Different EH schemes give different meanings to the three arguments,
but the first argument indicates whether the catch should fire, the second is

+the localescape index of the exception object, and the third is the code to run
to catch the exception.
For Windows C++ exception handling, the first argument for a catch handler is a
pointer to the RTTI type descriptor for the object to catch. The second
-argument is an index into the argument list of the ``llvm.frameescape`` call in
+argument is an index into the argument list of the ``llvm.localescape`` call in
the main function. The exception object will be copied into the provided stack
object. If the exception object is not required, this argument should be -1.
The third argument is a pointer to a function implementing the catch. This
