Standard get_longjmp_target implementation, similar to what is in arm-tdep.c. Actual value of jb_pc should be set in init_osabi methods of particular OS/ABI implementations. gdb/ChangeLog: * arc-tdep.h (struct gdbarch_tdep) <jb_pc>: New field. * arc-tdep.c (arc_get_longjmp_target): New function. (arc_gdbarch_init): Set get_longjmp_target if jb_pc is non-negative. (arc_dump_tdep): Print jb_pc.
