| 32 | -- This package provides the interfaces for proper handling of restriction | |
| 33 | -- No_Standard_Allocators_After_Elaboration. It is used only by programs | |
| 34 | -- which use this restriction. | |
| 35 | ||
| 36 | package System.Elaboration_Allocators is | |
| 37 | pragma Preelaborate; | |
| 38 | ||
| 39 | procedure Mark_Start_Of_Elaboration; | |
| 40 | -- Called right at the start of main elaboration if the program activates | |
| 41 | -- restriction No_Standard_Allocators_After_Elaboration. We don't want to | |
| 42 | -- rely on the normal elaboration mechanism for marking this event, since | |
| 43 | -- that would require us to be sure to elaborate this first, which would | |
| 44 | -- be awkward, and it is convenient to have this package be Preelaborate. | |
| 45 | ||
| 46 | procedure Mark_End_Of_Elaboration; | |
| 47 | -- Called when main elaboration is complete if the program has activated | |
| 48 | -- restriction No_Standard_Allocators_After_Elaboration. This is the point | |
| 49 | -- beyond which any standard allocator use will violate the restriction. | |
| 50 | ||
| 51 | procedure Check_Standard_Allocator; | |
| 52 | -- Called as part of every allocator in a program for which the restriction | |
| 53 | -- No_Standard_Allocators_After_Elaboration is active. This will raise an | |
| b3181992 | 54 | -- exception (Storage_Error with an appropriate message) if it is called |
| b3b26ace AC |
55 | -- after the call to Mark_End_Of_Elaboration. |
