MIPS16/opcodes: Keep the LSB of PC-relative offsets in disassembly
Correct the disassembly of the PC-relative immediate argument of the
MIPS16 synthetic LA, LW, DLA and LD instructions and do not mask the
LSB, which in this case is a part of the data address rather than the
ISA bit and has to be fully presented.
opcodes/
* mips-dis.c (print_insn_arg): Only clear the ISA bit for jumps
and branches and not synthetic data instructions.
binutils/
* testsuite/binutils-all/mips/mips16-undecoded.d: Adjust the
disassembly of PC-relative LA and LW synthetic instructions.
