	                 ChangeLog 

Log message:
	* alpha-osf1-tdep.c (alpha_osf1_init_abi): Unfortunately,
	procfs appears to be broken when debugging on multi-processor
	machines. So enable software single stepping in order to avoid
	using the procfs interface to do next/step operations, using
	internal breakpoints instead.
	
	* infrun.c (handle_inferior_event): Readjust the stop_pc by
	DECR_PC_AFTER_BREAK when hitting a single step breakpoint, to
	make this pc address equal to the value it would have if the
	system stepping capability was used. Also set a new flag used
	to ensure that we don't readjust the PC one more time later.
	
	* breakpoint.c (bpstat_stop_status): Do not adjust the PC
	address by DECR_PC_AFTER_BREAK when software single step is
	in use for this architecture, as this has already been taken
	care of in handle_inferior_event().
