H.J. Lu 6bf4a34047 gold: Properly align the NT_GNU_PROPERTY_TYPE_0 note
The NT_GNU_PROPERTY_TYPE_0 note should be aligned to 8 bytes for 64-bit
ELF as specified by gABI.  A note section can be only placed in a PT_NOTE
segment with the same alignment.

	PR gold/22914
	PR gold/23535
	* layout.cc (Layout::attach_allocated_section_to_segment): Place
	a note section in a PT_NOTE segment with the same alignment.  Set
	the alignment of the PT_NOTE segment from the alignment of the
	note section.
	(Layout::create_note): Align the NT_GNU_PROPERTY_TYPE_0 note to 8
	bytes for 64-bit ELF.
	(Layout::segment_precedes): Place segments with larger alignments
	first.
	* output.cc (Output_segment::Output_segment): Initialize align_.
	* output.h (Output_segment): Add align, set_align and align_.
	* testsuite/Makefile.am (gnu_property_test.stdout): Pass -lhSWn
	to $(TEST_READELF).
	(gnu_property_test): Pass --build-id to ld.
	* testsuite/Makefile.in: Regenerated.
	* testsuite/gnu_property_test.sh (check_alignment): New.
	Use check_alignment to check the NT_GNU_PROPERTY_TYPE_0 note
	alignment.  Verify that there are 2 PT_NOTE segments.

		   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.
