Cary Coutant 374082dfab Fix gold to group sections correctly via linker script.
In PR 15370, it is noted that gold does not distinguish between
"*(.foo .bar)" and "*(.foo) *(.bar)" in linker scripts. In both
cases, gold groups all .foo sections together, followed by all
.bar sections, whereas in the first case, it should collect all
.foo and .bar sections in the order seen.

If you add sort specs, the Gnu linker has some bizarre corner
cases that I do not try to replicate. In particular,
"*(SORT_BY_NAME(.foo) SORT_BY_NAME(.bar))" does the same thing
as "*(.foo) *(.bar)". But if you apply a sort spec
to just one of several patterns, say, "*(SORT_BY_NAME(.foo) .bar)",
the Gnu linker will collect any .bar section it sees before the
first .foo, then all .foo sections, then all remaining .bar
sections. With this patch, if any of the input patterns have a
sort spec, gold will group them all as it did before; e.g.,
all .foo sections followed by all .bar sections.

		   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.
