Detected while working on the new warning. * exp_ch9.adb (Expand_N_Entry_Declaration): remove useless assignment to local variable. * sem_ch5.adb (Analyze_Assignment): set the last assignment component in more cases, in order to detect more unreferenced values. * sem_util.adb, sem_util.ads (Get_Enclosing_Object): return enclosing object for expression, if any. 2011-08-04 Eric Botcazou <ebotcazou@adacore.com> * exp_intr.adb (Expand_Binary_Operator_Call): Look at the RM size of the operand types instead of the Esize. 2011-08-04 Steve Baird <baird@adacore.com> * switch-b.adb (Scan_Binder_Switches): Add -P binder switch, used to enable CodePeer_Mode. * bindusg.adb (Display): Add help message describing -P binder switch. * gnat_ugn.texi: Document -P binder switch. * bindgen.adb (Gen_Main_Ada): If CodePeer_Mode is set, then call the user-defined main program directly.

That, in turn, causes Parent.Awake_Count to be accessed without locking Parent, which causes another race condition whose symptom is that Parent.Awake_Count can be off by 1 (either too high or too low). The solution is to lock Parent unconditionally, and then lock Acceptor, before reading Acceptor.Terminate_Alternative. From-SVN: r177352

Ada.Finalization.Heap_Management provides key functionality associated with controlled objects on the heap, their creation, finalization and reclamation. Type Finalization_Collection is effectively a wrapper which sits ontop of a storage pool and performs all necessary bookkeeping for all the objects it contains. Each access-to-controlled or access-to-class-wide type receives a collection as part of its expansion. The compiler generates buffer code and invokes Allocate / Deallocate to create and destroy allocated controlled objects. * a-finali.adb ("="): Removed. * a-finali.ads ("="): Removed. Controlled types no longer carry hidden fields Prev and Next. * ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.

To signal this, ali files carry field PF. * ali.ads: New field in type Unit_Record called Has_Finalizer. Add associated comment on field usage. * a-tags.adb (Get_RC_Offset): Removed.
