-
--- This package contains routines involved in the required expansions for
--- handling shared memory accesses for variables in Shared_Passive packages.
-
--- See detailed documentation in System.Shared_Storage spec for a full
--- description of the approach that is taken for handling distributed
--- shared memory. This expansion unit in the compiler is responsible
--- for generating the calls to routines in System.Shared_Storage.

-package Exp_Smem is
-
- procedure Expand_Shared_Passive_Variable (N : Node_Id);
- -- N is the identifier for a shared passive variable. This routine is
- -- responsible for determining if this is an assigned to N, or a
- -- reference to N, and generating the required calls to the shared
- -- memory read/write procedures.
-
- procedure Add_Shared_Var_Lock_Procs (N : Node_Id);
- -- The argument is a protected subprogram call, before it is rewritten
- -- by Exp_Ch9.Build_Protected_Subprogram_Call. This routine, which is
- -- called only in the case of an external call to a protected object
- -- that has Is_Shared_Passive set, deals with installing the required
- -- global lock calls for this case. It also generates the necessary
- -- read/write calls for the protected object within the lock region.
-
- procedure Make_Shared_Var_Procs (N : Node_Id);
- -- N is the node for the declaration of a shared passive variable. This
- -- procedure constructs and inserts the read and assignment procedures
- -- for the shared memory variable. See System.Shared_Storage for a full
- -- description of these procedures and how they are used.
