Maciej W. Rozycki 92cebb3dbe MIPS/GAS: Clear the ASE_MIPS16E2_MT flag for recalculation
Correct a commit 25499ac7ee ("MIPS16e2: Add MIPS16e2 ASE support") GAS
bug with the handling of the ASE_MIPS16E2_MT combination ASE flag, which
is not correctly calculated as `.set nomips16e2' and `.set nomt'
pseudo-ops are processed.  This leads to code like:

$ cat foo.s
	.set	nomt
	evpe
	.align	4, 0
$ cat bar.s
	.set	nomips16e2
	dvpe
	.align	4, 0
$

to successfully assemble where it should not:

$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o foo.o foo.s
$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o bar.o bar.s
$ objdump -m mips:16 -d foo.o

foo.o:     file format elf32-tradbigmips

Disassembly of section .text:

00000000 <.text>:
   0:	f027 6700 	evpe
	...

bar.o:     file format elf32-tradbigmips

Disassembly of section .text:

00000000 <.text>:
   0:	f026 6700 	dvpe
	...
$

This happens because ASE_MIPS16E2_MT once set in `mips_set_ase' is never
cleared.  Fix the problem by clearing it there before it is calculated
based on the ASE_MT and ASE_MIPS16E2 flags, making assembly fail as
expected:

$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o foo.o foo.s
foo.s: Assembler messages:
foo.s:2: Error: opcode not supported on this processor: mips32r3 (mips32r3) `evpe'
$ as -32 -mips32r3 -mmt -mips16 -mmips16e2 -o bar.o bar.s
bar.s: Assembler messages:
bar.s:2: Error: opcode not supported on this processor: mips32r3 (mips32r3) `dvpe'

		   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.
