David Malcolm 0e50b62468 Replace line_map union with C++ class hierarchy 
gcc/ChangeLog:
	* diagnostic.c (diagnostic_report_current_module): Strengthen
	local "new_map" from const line_map * to
	const line_map_ordinary *.
	* genmatch.c (error_cb): Likewise for local "map".
	(output_line_directive): Likewise for local "map".
	* input.c (expand_location_1): Likewise for local "map".
	Pass NULL rather than &map to
	linemap_unwind_to_first_non_reserved_loc, since the value is never
	read from there, and the value written back not read from here.
	(is_location_from_builtin_token): Strengthen local "map" from
	const line_map * to const line_map_ordinary *.
	(dump_location_info): Strengthen locals "map" from
	line_map *, one to const line_map_ordinary *, the other
	to const line_map_macro *.
	* tree-diagnostic.c (loc_map_pair): Strengthen field "map" from
	const line_map * to const line_map_macro *.
	(maybe_unwind_expanded_macro_loc): Add a call to
	linemap_check_macro when writing to the "map" field of the
	loc_map_pair.
	Introduce local const line_map_ordinary * "ord_map", using it in
	place of "map" in the part of the function where we know we have
	an ordinary map.  Strengthen local "m" from const line_map * to
	const line_map_ordinary *.

gcc/ada/ChangeLog:
	* gcc-interface/trans.c (Sloc_to_locus1): Strenghthen local "map"

	non-NULL.  Use it for typesafety.
	* files.c (cpp_make_system_header): Strengthen local "map" from
	const line_map * to const line_map_ordinary *.

README 

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.
