Maciej W. Rozycki 9f00292e69 MIPS/GAS: Use non-zero frag offset directly in PIC branch relaxation
Use frag symbols with a non-zero offset directly in `fix_new_exp' calls
made in PIC branch relaxation.  There is no need here to make a helper
symbol to hold the result of a `symbol+offset' calculation requested as
only branches to local symbols are relaxed and in this case the LO16
part of the PIC address load sequence will have the offset accounted for
in calculation against the local GOT entry retrieved as the GOT16 high
part.  Consequently actual code produed is identical whether a helper
symbol is used or the original `symbol+offset' expression used directly.
Verify that this is indeed the case with GAS and LD tests.

		   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.
