Joshua Oreman e173ea00c2 Fix problem with ICF where diffs in EH frame info is ignored.
PR gold/21066
	* gc.h (gc_process_relocs): Track relocations in .eh_frame sections
	when ICF is enabled, even though the .eh_frame sections themselves
	are not foldable.
	* icf.cc (get_section_contents): Change arguments to permit operation
	on just part of a section. Include extra identity regions in the
	referring section's contents recursively.
	(match_sections): Lock object here instead of in get_section_contents
	so that get_section_contents can operate recursively.
	(Icf::add_ehframe_links): New method.
	(Icf::find_identical_sections): Pass .eh_frame sections to
	add_ehframe_links(). Increase default iteration count from 2 to 3
	because handling exception info typically requires one extra iteration.
	* icf.h (Icf::extra_identity_list_): New data member with accessor.
	(is_section_foldable_candidate): Include .gcc_except_table sections.
	* options.h: Update documentation for new default ICF iteration count.
	* testsuite/Makefile.am (icf_test_pr21066): New test case.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/icf_test_pr21066.cc: New source file.
	* testsuite/icf_test_pr21066.sh: New test script.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
