target/m68k: correctly disassemble move16
"move16 %a0@+,%a1@" and "fmovel (cpid=3) %a0@-,%fpcr" share the same opcode. To fix that, backport the fix from binutils: 2005-11-10 Andreas Schwab <schwab@suse.de> * m68k-dis.c (print_insn_m68k): Only match FPU insns with coprocessor ID 1. Reported-by: Thomas Huth <huth@tuxfamily.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Tested-by: Thomas Huth <huth@tuxfamily.org> Message-Id: <20180625203559.21370-2-laurent@vivier.eu>
