Return -1 on memory error in print_insn_msp430
Disassemblers in opcodes return -1 on memory error, but msp430 doesn't
follow this convention. If I change GDB not to throw exception in
disassemble_info.memory_error_func and rely on the return value of
disassembler, I'll get the following output.
(gdb) disassemble 0x0,+8
Dump of assembler code from 0x0 to 0x8:
0x00000000: .word 0xffff; ????
0x00000002: .word 0xffff; ????
0x00000004: .word 0xffff; ????
0x00000006: .word 0xffff; ????
End of assembler dump.
This patch teaches print_insn_msp430 and its callees to return -1
on memory error.
opcodes:
2017-01-12 Yao Qi <yao.qi@linaro.org>
* msp430-dis.c (msp430_singleoperand): Return -1 if
msp430dis_opcode_signed returns false.
(msp430_doubleoperand): Likewise.
(msp430_branchinstr): Return -1 if
msp430dis_opcode_unsigned returns false.
(msp430x_calla_instr): Likewise.
(print_insn_msp430): Likewise.
