* gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
* gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
to detect constant renamings. Be prepared for specific pattern of
renamed object based on function calls. Create a constant object
for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
to gnat_stabilize_reference and tidy up. Remove redundant tests.
(elaborate_expression_1): Remove obsolete test and tidy up.
* gcc-interface/trans.c (Call_to_gnu): Do not stabilize In/Out or Out
parameters passed by reference.
(gnat_to_gnu) <N_Selected_Component>: Remove redundant protection again
side-effects.
Use gnat_protect_expr instead of gnat_stabilize_reference for general
protection against side-effects.
* gcc-interface/utils2.c (gnat_stable_expr_p): New predicate.
(gnat_save_expr): Invoke it.
(gnat_protect_expr): Likewise.
(gnat_stabilize_reference_1): Likewise. Remove useless propagation
of TREE_THIS_NOTRAP.
(gnat_stabilize_reference): Remove parameter and adjust throughout.
Delete ADDR_EXDR, COMPOUND_EXPR and CONSTRUCTOR cases.
Restrict CALL_EXPR case to atomic loads and tweak ERROR_MARK case.

This directory contains the GNU Compiler Collection (GCC).
The GNU Compiler Collection is free software. See the files whose
names start with COPYING for copying permission. The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.
The directory INSTALL contains copies of the installation information
as HTML and plain text. The source of this information is
gcc/doc/install.texi. The installation information includes details
of what is included in the GCC sources and what files GCC installs.
See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information. An online readable
version of the manual is in the files gcc/doc/gcc.info*.
See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
