Maciej W. Rozycki 88a7ef1689 MIPS16/GAS: Restore unsupported relocation diagnostics
Correct a MIPS16 relocation handling regression in GAS introduced with:

commit 177b4a6ad0
Author: Alexandre Oliva <aoliva@redhat.com>
Date:   Mon Mar 18 18:56:18 2002 +0000

discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>,
which removed a preparatory call to `mips16_extended_frag' previously
made from `md_estimate_size_before_relax'.  As a result the function is
never called with its `sec' parameter non-NULL and consequently all the
unsupported relocation checks within are dead and never trigger, causing
any unhandled relocations to silently resolve to 0.  Unfortunately there
was no sufficient test suite coverage back then to catch this.

Remove all dead code then, and all the associated comments.  Update the
remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass
the relocation section as the `sec' parameter and use it to mark frags
which require an external relocation, as extended.  Finally handle any
outstanding MIPS16 relocations in `md_convert_frag' and report an error
since we don't support any except with percent operators.

	gas/
	* config/tc-mips.c (append_insn): Use any `O_symbol' expression
	unchanged with relaxed MIPS16 instructions.
	(mips16_extended_frag): Adjust accordingly.  Return 1 right
	away if a relocation will be required for the symbol requested.
	Remove dead first relaxation pass code.
	(mips_relax_frag): Pass `sec' down to `mips16_extended_frag'.
	(md_convert_frag): Adjust symbol value calculation.  Raise an
	error if a relocation is required for the symbol requested.

README

		   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.
