2016-12-12Handle memory error in print_insn_rxYao Qi1-4/+28
Nowadays, memory error in rx disassembly is not handled, so if I start a fresh GDB, and disassemble, (gdb) set architecture rx The target architecture is assumed to be rx (gdb) disassemble 0x0,+4 Dump of assembler code from 0x0 to 0x4: 0x00000000: brk 0x00000001: brk 0x00000002: brk 0x00000003: brk the output is wrong. This patch adds code to call dis->memory_error_func on memory error, and longjmp to print_insn_rx. With this patch applied, (gdb) set architecture rx The target architecture is assumed to be rx (gdb) disassemble 0,+4 Dump of assembler code from 0x0 to 0x4: 0x00000000: Cannot access memory at address 0x0 opcodes: 2016-12-12 Yao Qi <yao.qi@linaro.org> * rx-dis.c: Include <setjmp.h> (struct private): New. (rx_get_byte): Check return value of read_memory_func, and call memory_error_func and OPCODES_SIGLONGJMP on error. (print_insn_rx): Call OPCODES_SIGSETJMP.
