+ * hpux-core.c: New file; backend for HP/UX style core files.
+ * bfd.c (struct _bfd): Renamed hppa_core_data field to
+ hpux_core_data.
+ * bfd-in2.h: Updated.
+ * hppa.c (make_bfd_asection, hppa_core_file_p,
+ hppa_core_file_failing_command, hppa_core_file_failing_signal,
+ hppa_core_file_matches_executable_p): Moved into hpux-core.c.
+ Removed from target vector.
+ * libhppa.h (struct hppa_core_struct and accessor macros): Moved
+ into hpux-core.c.
+ * targets.c: If HPUX_CORE is defined, add hpux_core_vec to
+ target list.
+ * config/hp300.mh (HDEFINES): Set to -DHPUX_CORE.
+ (HDEPFILES): Set to hpux-core.o.
+ * config/hppabsd.mh, config/hppahpux.mh: Likewise.
+ * hosts/hp300.h (HOST_HP300HPUX): Define.
+ * Makefile.in (OPTIONAL_BACKENDS): Added sco-core.o,
+ aix386-core.o, hpux-core.o.
+ (sco-core.o, aix386-core.o, hpux-core.o): New dependencies.
+
* reloc.c (enum complain_overflow): New enumeration with the
various flavours of overflow checking.
(srtuct reloc_howto_struct): Changed complain_on_overflow field
return (0);
