* gdbarch.sh (GET_LONGJMP_TARGET): Add rule.
* 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.
