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.
