David Malcolm 88fa5555a3 On-demand locations within string-literals
gcc/c-family/ChangeLog:

	* charset.c (cpp_substring_ranges::cpp_substring_ranges): New
	constructor.
	(cpp_substring_ranges::~cpp_substring_ranges): New destructor.
	(cpp_substring_ranges::add_range): New method.
	(cpp_substring_ranges::add_n_ranges): New method.
	(_cpp_valid_ucn): Add "char_range" and "loc_reader" params; if
	they are non-NULL, read position information from *loc_reader
	and update char_range->m_finish accordingly.
	(convert_ucn): Add "char_range", "loc_reader", and "ranges"
	params.  If loc_reader is non-NULL, read location information from
	it, and update *ranges accordingly, using char_range.
	Conditionalize the conversion into tbuf on tbuf being non-NULL.
	(convert_hex): Likewise, conditionalizing the call to
	emit_numeric_escape on tbuf.
	(convert_oct): Likewise.
	(convert_escape): Add params "loc_reader" and "ranges".  If
	loc_reader is non-NULL, read location information from it, and
	update *ranges accordingly.  Conditionalize the conversion into
	tbuf on tbuf being non-NULL.
	(cpp_interpret_string): Rename to...
	(cpp_interpret_string_1): ...this, adding params "loc_readers" and
	"out".  Use "to" to conditionalize the initialization and usage of
	"tbuf", such as running the converter.  If "loc_readers" is
	non-NULL, use the instances within it, reading location
	information from them, and passing them to convert_escape; likewise
	write to "out" if loc_readers is non-NULL.  Check for leading
	quote and issue an error if it is not present.  Update boundary
	check from "== limit" to ">= limit" to protect against erroneous
	location values to calls that are not parsing string literals.
	(cpp_interpret_string): Reimplement in terms to
	cpp_interpret_string_1.
	(noop_error_cb): New function.
	(cpp_interpret_string_ranges): New function.
	(cpp_string_location_reader::cpp_string_location_reader): New
	constructor.
	(cpp_string_location_reader::get_next): New method.
	* include/cpplib.h (class cpp_string_location_reader): New class.
	(class cpp_substring_ranges): New class.
	(cpp_interpret_string_ranges): New prototype.
	* internal.h (_cpp_valid_ucn): Add params "char_range" and
	"loc_reader".
	* lex.c (forms_identifier_p): Pass NULL for new params to
	_cpp_valid_ucn.

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.
