* gdbarch.c gdbarch.h: Regenerate. * breakpoint.c (create_longjmp_breakpoint): Always compile this function. (breakpoint_reset): Test GET_LONGJMP_TARGET_P(). * infrun.c (GET_LONGJMP_TARGET): Delete default definition. (handle_inferior_event): Test GET_LONGJMP_TARGET_P(). * arm-tdep.h (struct gdbarch_tdep): Add jb_pc and jb_elt_size fields. * arm-tdep.c (arm_get_longjmp_target): New function. (arm_gdbarch_init): Initialize jb_pc to -1. If ABI handler changes this to a positive value register arm_get_longjmp_target as the longjmp handler. * arm-linux-tdep.c (arm_get_longjmp_target): Delete. (arm_linux_init_abi): Set up longjmp description in tdep. * armnbsd-nat.c (get_longjmp_target): Delete. * armnbsd-tdep.c (arm_netbsd_init_abi_common): Set up longjmp description in tdep. * config/arm/tm-nbsd.h (JB_ELEMENT_SIZE, JB_PC): Delete. (get_longjmp_target): Delete declaration. (GET_LONGJMP_TARGET): Delete. * config/arm/tm-linux.h (arm_get_longjmp_target): Delete declaration. (GET_LONGJMP_TARGET): Delete.
