PR tree-optimization/93210
	* fold-const.h (native_encode_initializer,
	can_native_interpret_type_p): Declare.
	* fold-const.c (native_encode_string): Fix up handling with off != -1,
	simplify.
	(native_encode_initializer): New function, moved from dwarf2out.c.
	Adjust to native_encode_expr compatible arguments, including dry-run
	and partial extraction modes.  Don't handle STRING_CST.
	(can_native_interpret_type_p): No longer static.
	* gimple-fold.c (fold_ctor_reference): For native_encode_expr, verify
	offset / BITS_PER_UNIT fits into int and don't call it if
	can_native_interpret_type_p fails.  If suboff is NULL and for
	CONSTRUCTOR fold_{,non}array_ctor_reference returns NULL, retry with
	native_encode_initializer.
	(fold_const_aggregate_ref_1): Formatting fix.
	* dwarf2out.c (native_encode_initializer): Moved to fold-const.c.
	(tree_add_const_value_attribute): Adjust caller.

	* gcc.dg/pr93210.c: New test.
	* g++.dg/opt/pr93210.C: New test.

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.
