| -- This package provides the interfaces for proper handling of restriction |
| -- No_Standard_Allocators_After_Elaboration. It is used only by programs |
| -- which use this restriction. |
| |
| package System.Elaboration_Allocators is |
| pragma Preelaborate; |
| |
| procedure Mark_Start_Of_Elaboration; |
| -- Called right at the start of main elaboration if the program activates |
| -- restriction No_Standard_Allocators_After_Elaboration. We don't want to |
| -- rely on the normal elaboration mechanism for marking this event, since |
| -- that would require us to be sure to elaborate this first, which would |
| -- be awkward, and it is convenient to have this package be Preelaborate. |
| |
| procedure Mark_End_Of_Elaboration; |
| -- Called when main elaboration is complete if the program has activated |
| -- restriction No_Standard_Allocators_After_Elaboration. This is the point |
| -- beyond which any standard allocator use will violate the restriction. |
| |
| procedure Check_Standard_Allocator; |
| -- Called as part of every allocator in a program for which the restriction |
| -- No_Standard_Allocators_After_Elaboration is active. This will raise an |
| -- exception (Program_Error with an appropriate message) if it is called |
| -- after the call to Mark_End_Of_Elaboration. |
