	* breakpoint.h (enum bptype) <bp_hp_step_resume>: New.
	(enum bpstat_what_main_action): Move BPSTAT_WHAT_STEP_RESUME
	before BPSTAT_WHAT_STOP_SILENT.  Add BPSTAT_WHAT_HP_STEP_RESUME
	at the end.
	* breakpoint.c (update_breakpoints_after_exec): Also delete hp
	step-resume breakpoints.
	(print_it_typical): Handle bp_hp_step_resume.
	(bpstat_what): Ditto.
	(bptype_string): Ditto.
	(print_one_breakpoint_location): Ditto.
	(allocate_bp_location): Ditto.
	(mention): Ditto.
	(breakpoint_re_set_one): Ditto.
	* infrun.c (handle_inferior_event): Adjust.  Split
	BPSTAT_WHAT_STEP_RESUME handling in BPSTAT_WHAT_STEP_RESUME and
	BPSTAT_WHAT_HP_STEP_RESUME.
	(insert_step_resume_breakpoint_at_sal): Rename to ...
	(insert_step_resume_breakpoint_at_sal_1): ... this.  Add bptype
	parameter.  Handle it.
	(insert_step_resume_breakpoint_at_sal): Reimplement on top of
	insert_step_resume_breakpoint_at_sal_1.
	(insert_step_resume_breakpoint_at_frame): Rename to ...
	(insert_hp_step_resume_breakpoint_at_frame): ... this.  Adjust to
	set a high-priority step-resume breakpoint.
	(insert_step_resume_breakpoint_at_frame): Adjust comment.
	(insert_step_resume_breakpoint_at_caller): Ditto.

	gdb/testsuite/
	* gdb.reverse/next-reverse-bkpt-over-sr.exp: New test.
