-- Expand routines for pragmas
with Types; use Types;
package Exp_Prag is
procedure Expand_N_Pragma (N : Node_Id);
procedure Expand_Pragma_Always_Terminates (Prag : Node_Id);
-- This routine only exists for consistency with other pragmas, since
-- Always_Terminates has no meaningful expansion.
procedure Expand_Pragma_Contract_Cases
(CCs : Node_Id;
Subp_Id : Entity_Id;
Decls : List_Id;
Stmts : in out List_Id);
-- Given pragma Contract_Cases CCs, create the circuitry needed to evaluate
-- case guards and trigger consequence expressions. Subp_Id is the related
-- subprogram for which the pragma applies. Decls are the declarations of
-- Subp_Id's body. All generated code is added to list Stmts. If Stmts is
-- No_List on entry, a new list is created.
procedure Expand_Pragma_Exceptional_Cases (Prag : Node_Id);
-- Given pragma Exceptional_Cases Prag, create the circuitry needed to
-- catch exceptions and evaluate consequence expressions.
procedure Expand_Pragma_Initial_Condition
(Pack_Id : Entity_Id;
N : Node_Id);
-- Verify the run-time semantics of pragma Initial_Condition when it
-- applies to package Pack_Id. N denotes the related package spec or
-- body.
procedure Expand_Pragma_Subprogram_Variant
(Prag : Node_Id;
Subp_Id : Entity_Id;
Body_Decls : List_Id);
-- Given pragma Subprogram_Variant Prag, create the circuitry needed
-- to evaluate variant expressions at the subprogram entry and at the
-- recursive call. Subp_Id is the related subprogram for which the pragma
-- applies and Body_Decls are its body declarations. On exit, the argument
-- of Prag is replaced with a reference to procedure with checks for the
-- variant expressions.
