	* solib-irix.c (enable_break): Likewise.
	* objfiles.c (init_entry_point_info): Stop using INVALID_ENTRY_POINT.
	Initialize EI.ENTRY_POINT_P.
	(entry_point_address): Rename to ...
	(entry_point_address_query): ... a new function.  Use EI.ENTRY_POINT_P.
	(entry_point_address): New function.
	(objfile_relocate): Use EI.ENTRY_POINT_P.
	* objfiles.h (struct entry_info): Simplify entry_point comment.  New
	field entry_point_p.
	(INVALID_ENTRY_POINT): Remove.
	(entry_point_address_query): New prototype.
