* gimplify.c (gimplify_modify_expr_rhs) <VAR_DECL>: Do not do a direct
assignment from the constructor either if the target is volatile.
ada/
* einfo.ads (Is_True_Constant): Lift restriction on atomic objects.
* sinfo.ads (Object Declaration): Likewise.
(Assignment Statement): Likewise.
* freeze.adb (Expand_Atomic_Aggregate): Remove useless test.
Do not force Is_True_Constant to false on the temporary.
(Freeze_Entity): Do not force Is_True_Constant to false on names on
the RHS of object declarations.
* gcc-interface/trans.c (lvalue_required_p) <N_Object_Declaration>:
New case. Return 1 if the object is atomic.
<N_Assignment_Statement>: Likewise.
