Note: Some of the ns32k-specific files do require gcc to compile at present.
This will be fixed.

+
+ * reloc.c (enum bfd_reloc_code_real, bfd_type, struct
+ reloc_howto_struct, reloc_howto_type, HOWTO, HOWTO2): Copied
+ changes over from bfd-in2.h so they get generated properly next
+ time someone runs "make headers".
+ * bfd-in2.h: Rebuilt.
+
+ * targets.c (netbsd532_vec, pc532mach_vec): Declare const.
+ (m88kmach3_vec): Restore deleted declaration.
+
+ * configure.in: Alphabetize target vector names.
+
+ * config/pc532mach.mh: New file.
+ (HDEPFILES, HDEFINES): Define here.
+ * config/pc532-mach.mt (HDEPFILES, HDEFINES): Deleted.
+ * config/ns32k-netbsd.mt (HDEPFILES, HDEFINES): Deleted.

+ Sun Jul 10 00:04:20 1994 Ian Dall (dall@hfrd.dsto.gov.au)
+
+ * pc532-mach.c: New File. pc532-mach a.out format.
+
+ * netbsd532.c: New file. pc532-netbsd532 a.out format.
+
+ * hosts/pc532mach.h: New file. pc532-mach host support.
+
+ * cpu-ns32k.c: New file. ns32k support cpu specific code rather
+ than format specific code.
+
+ * config/pc532-mach.mt: New file. Support for pc532-mach target.
+
+ * config/ns32k-netbsd.mt: New file. Support for netbsd532 target.
+
+ * aout-ns32k.c, aout-ns32k.h: New files supporting aout format for
+ ns32k series.
+
+ * targets.c: Add netbsd532_vec and pc532machaout_vec into
+ bfd_target_vector array. Move netbsd386_vec to alphabetic order
+ location.
+
+ * reloc.c (_bfd_final_link_relocate) Add support for
+ special_function1 in howto.
+
+ * libaout.h: add M_NS32032, M_NS32532, M_532_NETBSD entries in
+ machine_type enum.
+
+ * configure.in: add pc532mach_vec and netbsd532_vec entries.
+
+ * config.bfd: add pc532mach host entries. Use for both
+ ns32k-pc532-mach and ns32k-pc532-netbsd.
+
+ * config.bfd: it doesn't work to use i386-mach3 for ns32k*-*-mach.
+ add ns32k-pc532-mach* and ns32k-*-netbsd* entries.
+
+ * bfd-in2.h: Add ns32k specific relocations to bfd_reloc_code_real
+ enum.
+
+ * bfd-in2.h: Add special_function1 to struct howto. Change HOWTO
+ and NEWHOWTO macros to make special_function1 NULL. Neww HOWTO2
+ macro.
+
+ * bfd-in2.h: Split definition of struct reloc_howto_struct
+ and corresponding typedef into two statements.
+
+ * bfd-in2.h: Add entry bfd_arch_ns32k to bfd_architecture enum.
+
+ * archures.c: Add bfd_ns32k_arch prototype, and entry in
+ archures_init_table.
+
+ * aoutx.h (aout_link_reloc_link_order): Allow for target dependent
+ MY_put_reloc macro. Allow for target dependent special_function1
+ to apply the relocation.
+
+ * aoutx.h (aout_link_input_section_std): Allow for target
+ dependent determination of reloc howto. Allow for target dependent
+ special_function1 to apply the relocation.
+
+ * aoutx.h (get_reloc_upper_bound): Detect bss and return 0.
+
+ * aoutx.h (slurp_reloc_table): Detect bss and succesfully read
+ zero reloc entries.
+
+ * aoutx.h (machine_type): Add bfd_arch_ns32k case.
+
+ * aoutx.h: Stat to determine executable status if STAT_FOR_EXEC
+ is defined (not just MACH). Use fstat instead of stat and check
+ for fstat error.
+
+ * aoutx.h: Allow target dependent swap_std_reloc_{in,out}.
+
+ * aoutx.h: Allow CTORS reloc info to be in target dependent reloc
+ table.
+
+ * aout-target.h: Apply SWAP_MAGIC (if defined) after
+ swap_exec_header_in, otherwise we have magic in the wrong order.
