	* breakpoint.c (update_breakpoints_after_exec): Delete bp_longjmp
	and bp_longjmp_resume breakpoints.
	(breakpoint_address_is_meaningful): Claim bp_longjmp_resume as
	meaningful.
	(create_longjmp_breakpoint): Don't create bp_longjmp_resume
	breakpoints.  Create bp_longjmp breakpoints as momentary
	breakpoints.
	(enable_longjmp_breakpoint): Delete.
	(set_longjmp_breakpoint): New.
	(disable_longjmp_breakpoint): Delete.
	(delete_longjmp_breakpoint): New.
	(set_longjmp_resume_breakpoint): Delete.
	(set_momentary_breakpoint_at_pc): New.
	(breakpoint_re_set_one): Don't delete bp_longjmp and
	bp_longjmp_resume breakpoints.
	(breakpoint_re_set): Don't create longjmp and longjmp-resume
	breakpoints.

	* infrun.c (step_resume_breakpoint): Add comment.
	(struct execution_control_state): Delete handling_longjmp member.
	(init_execution_control_state). Don't clear handling_longjmp.
	(context_switch): Don't context switch handling_longjmp.
	(handle_inferior_event): If handling a bp_longjmp breakpoint,
	create a bp_longjmp_resume breakpoint, and set it as current
	step_resume_breakpoint, then step over the longjmp breakpoint.  If
	handling a bp_longjmp_resume breakpoint, don't delete the longjmp
	breakpoint, delete the longjmp-resume breakpoint, and stop
	stepping.
	(currently_stepping): Remove handling_longjmp from expression.
	(insert_step_resume_breakpoint_at_sal): Update comment.
	(insert_longjmp_resume_breakpoint): New.

	* breakpoint.h (set_momentary_breakpoint_at_pc): Declare.
	(enable_longjmp_breakpoint, disable_longjmp_breakpoint): Delete
	declarations.
	(set_longjmp_breakpoint, delete_longjmp_breakpoint): Declare.
	(set_longjmp_resume_breakpoint): Delete declaration.

	* gdbthread.h (save_infrun_state): Remove handling_longjmp
	parameter.
	(load_infrun_state): Delete *handling_longjmp parameter.
	* thread.c (save_infrun_state): Remove handling_longjmp parameter.
	Update body.
	(load_infrun_state): Delete *handling_longjmp parameter.  Update
	body.

	* infcmd.c (disable_longjmp_breakpoint_cleanup): Delete.
	(delete_longjmp_breakpoint_cleanup): New.
	(step_1): Call set_longjmp_breakpoint instead of
	enable_longjmp_breakpoint.  Use delete_longjmp_breakpoint_cleanup
	instead of disable_longjmp_breakpoint_cleanup when making cleanup.
	(step_1_continuation): Pass thread id in the continuation args to
	step_once.
	(step_once): Add thread parameter.  Pass thread id the the
	continuation.

gdb/testsuite/
	* gdb.cp/annota2.exp: Adjust to breakpoints invalidations at
	different times.
