* sem_aggr.adb (Resolve_Extension_Aggregate): Warn on the use of C++
constructors that leave the object partially initialized.
* exp_atag.ads, exp_atags.adb (Build_Inherit_CPP_Prims): New subprogram
that copies from parent of Typ the dispatch table slots of inherited
C++ primitives. It handles primary and secondary dispatch tables.
* einfo.adb (Related_Type): Moved from Node26 to Node27. Required to
use this attribute with E_Variable entities.
(Set_Is_Tag): Relax assertion to allow its use with variables that
store tags.

that store the tag of a C++ class.

with E_Variable entities.

closest ancestor of a type that is a C++ type.
(Has_Suffix): New subprogram. Used in assertions to check the suffix of
internal entities.

instance in derivations of C++ types.
* exp_tss.adb (CPP_Init_Proc): New subprogram.

store the C++ tag values after the first invocation of the C++
constructor.
(Build_CPP_Init_DT): New subprogram.
(Set_CPP_Constructors): New implementation that builds an IP for each
CPP constructor. These IP are wrappers of the C++ constructors that,
after the first invocation of the constructor, read the C++ tags from
the object and save them locally. These copies of the C++ tags are used
by the IC routines to initialize tables of Ada derivations of CPP types.
(Write_DT): Indicate what primitives are imported from C++
* exp_disp.ads (CPP_Num_Prims): New subprogram.
(Has_CPP_Constructors): New subprogram.
* exp_aggr.adb (Build_Record_Aggr_Code): For derivations of C++ types
invoke the IC routine to inherit the slots of the parents.

(Is_Variable_Size_Record): Factorize code calling
Is_Variable_Size_Array.
(Build_CPP_Init_Procedure): New subprogram that builds the tree
corresponding to the procedure that initializes the C++ part of the
dispatch table of an Ada tagged type that is a derivation of a CPP type.
(Build_Init_Procedure): Adding documentation plus code reorganization to
leave more clear the construction of the IP with C++ types.
(Expand_Freeze_Record_Type): Delay call to Set_CPP_Constructors because
it cannot be called after Make_Tags has been invoked.
(Inherit_CPP_Tag): Removed.
(Init_Secondary_Tags): For derivations of CPP types, warn on tags
located at variable offset.
* freeze.ads: Minor reformating.
* sem_ch8.adb (Write_Scopes): Add pragma export. Required to have it
available in gdb.
* gcc-interface/Make-lang.in: Update dependencies.

constant-fold discriminant reference if the constraint is an object
with non-static expression. Expression may contain volatile references
in the presence of renamings.
