548 Has_Delayed_Aspect, used to defer resolution of an aggregate
549 expression when the object declaration carries aspects Address
551 * freeze.adb (Freeze_Object_Declaration): New subsidiary procedure
552 to Freeze_Entity. In addition to the previous processing steps
553 at the freeze point of an object, this procedure also handles
554 aggregates in object declarations, when the declaration carries

577 incomplete class-wide type, the subprogram must have a delayed
578 freeze even though the opertation is not a primitive of the
579 type. THis ensures that the backend can recover the full view
580 when elaborating the subprogram declaration.

610 can be given the proper size.
611 * sem_util.adb (Build_Default_Subtype): If the subtype is created
612 for a record discriminant, do not analyze the declarztion at
613 once because it is added to the freezing actions of the enclosing
616 2015-05-12 Robert Dewar <dewar@adacore.com>

1067 overloaded left-hand side when the alternatives on the right
1068 hand side are literals of some universal type. Use first

1073 * exp_ch7.adb (Make_Set_Finalize_Address_Call): Use underlying
1074 type to retrieve designated type, because the purported access
1075 type may be a partial (private) view, when it is declared in
1076 the private part of a nested package, and finalization actions
1077 are generated when completing compilation of enclosing unit.

1290 expanding a 'Input attribute reference for a class-wide type,
1291 do not generate a separate object declaration for the controlling
1292 tag dummy object; instead, generate the expression inline in the
1293 dispatching call. Otherwise, the declaration (which involves a
1294 call to String'Input, returning a dynamically sized value on the
1295 secondary stack) will be expanded outside of proper secondary
1296 stack mark/release operations, and will thus cause a secondary

1506 just equivalent ones. Simplifies value tracing in GNATProve.

3225 * set_targ.adb (Long_Double_Index): The index at which "long
