45 -- Given a handled statement sequence, HSS, for which the At_End_Proc
46 -- field is set, and which currently has no exception handlers, this
47 -- procedure expands the special exception handler required.
48 -- This procedure also create a new scope for the given Block, if
49 -- Block is not Empty.
51 procedure Expand_Exception_Handlers (HSS : Node_Id);
52 -- This procedure expands exception handlers, and is called as part
53 -- of the processing for Expand_N_Handled_Sequence_Of_Statements and
54 -- is also called from Expand_At_End_Handler. N is the handled sequence
55 -- of statements that has the exception handler(s) to be expanded. This
56 -- is also called to expand the special exception handler built for
57 -- accept bodies (see Exp_Ch9.Build_Accept_Body).
59 function Get_Local_Raise_Call_Entity return Entity_Id;
60 -- This function is provided for use by the back end in conjunction with
61 -- generation of Local_Raise calls when an exception raise is converted to
62 -- a goto statement. If Local_Raise is defined, its entity is returned,
63 -- if not, Empty is returned (in which case the call is silently skipped).
65 function Get_RT_Exception_Entity (R : RT_Exception_Code) return Entity_Id;
66 -- This function is provided for use by the back end in conjunction with
67 -- generation of Local_Raise calls when an exception raise is converted to
68 -- a goto statement. The argument is the reason code which would be used
69 -- to determine which Rcheck_nn procedure to call. The returned result is
70 -- the exception entity to be passed to Local_Raise.
72 function Is_Non_Ada_Error (E : Entity_Id) return Boolean;
73 -- This function is provided for Gigi use. It returns True if operating on
74 -- VMS, and the argument E is the entity for System.Aux_Dec.Non_Ada_Error.
75 -- This is used to generate the special matching code for this exception.
