ada-tree.h (DECL_RETURN_VALUE_P): New macro.
* gcc-interface/ada-tree.h (DECL_RETURN_VALUE_P): New macro.
* gcc-interface/gigi.h (gigi): Remove useless attribute.
(gnat_gimplify_expr): Likewise.
(gnat_to_gnu_external): Declare.
* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Constant>: Factor out
code dealing with the expression of external constants into...
Invoke gnat_to_gnu_external instead.
<E_Variable>: Invoke gnat_to_gnu_external to translate renamed objects
when not for a definition. Deal with COMPOUND_EXPR and variables with
DECL_RETURN_VALUE_P set for renamings and with the case of a dangling
'reference to a function call in a renaming. Remove obsolete test and
adjust associated comment.
* gcc-interface/trans.c (Call_to_gnu): Set DECL_RETURN_VALUE_P on the
temporaries created to hold the return value, if any.
(gnat_to_gnu_external): ...this. New function.
* gcc-interface/utils.c (create_var_decl): Detect a constant created
to hold 'reference to function call.
* gcc-interface/utils2.c (build_unary_op) <ADDR_EXPR>: Add folding
for COMPOUND_EXPR in the DECL_RETURN_VALUE_P case.
