11dd08e9a0 MIPS16/opcodes: Respect ISA and ASE in disassembly
Limit MIPS16 instruction disassembly according to the ISA level and ASE
set selected, as with the regular MIPS and microMIPS instruction sets.
Retain the property of `objdump -m mips:16' disassembling all MIPS16
instructions however, regardless of any ISA level recorded in the binary
examined.

To validate the disassembler use the GAS test suite for its convenience
of running tests across multiple ISAs, even though placing the tests in
the binutils test suite would be more appropriate.  Adjust the single
binutils test which depends on 64-bit instruction disassembly to have
the ISA level required actually recorded in the binary examined.

	opcodes/
	* mips-dis.c (mips_arch_choices): Use ISA_MIPS64 rather than
	ISA_MIPS3 as the `isa' selection in the `bfd_mach_mips16' entry.
	(print_insn_mips16): Check opcode entries for validity against
	the ISA level and ASE set selected.

	binutils/
	* testsuite/binutils-all/mips/mips16-undecoded.s: Use `.module'
	rather than `.set' to set the ISA level.

	* testsuite/gas/mips/mips16-sub.d: New test.

92708ceca5 MIPS/opcodes: Fix undecoded MIPS16 extended instruction bit disassembly
Correct the disassembly of hardware don't cares in MIPS16 extended
instructions.  Rather than e.g.:

   0:	f008 0231 	addiu	v0,sp,16433
   4:	f520 3260 	sll	v0,v1,-12

print:

   0:	f008 0231 	addiu	v0,sp,16401
   4:	f520 3260 	sll	v0,v1,20

respectively instead.

	opcodes/
	* mips-dis.c (print_mips16_insn_arg): Mask unused extended
	instruction bits out.

	binutils/
	* testsuite/binutils-all/mips/mips16-undecoded.d: New test.
	* testsuite/binutils-all/mips/mips16-undecoded.s: New test
	source.
	* testsuite/binutils-all/mips/mips.exp: Run the new test.
