        * subsegs.c (subseg_set_rest): Compare segT values directly,
        without casting to int first.
 
+       * config/tc-ns32k.c (md_begin): Return value from hash_insert
+       should be pointer to const.  Don't call exit explicitly after
+       calling as_fatal; it won't return.
+       (convert_iif): Make local variable j be pointer to bit_fixS, since
+       that's how it's used.
+       (encode_operand, case 'b'): Ignore sprintf return value.  Don't try
+       converting freeptr to int and back.
+
+       Merged in NS32K support update from Ian Dall (dall@hfrd.dsto.gov.au):
+
+       * config/te-pc532mach.h: New file. pc532-mach target emulation.
+
+       * config/te-netbsd532.h: New file. Netbsd532 target emulation.
+
+       * config/tc-ns32k.h: Add definition of NOP_OPCODE.
+
+       * config/tc-ns32k.h: Add prototype for fix_new_ns32k_exp.
+
+       * config/tc-ns32k.h: Add BFD_ASSEMBLER support.
+
+       * config/tc-ns32k.c (tc_gen_reloc): New function for BFD_ASSEMBLER.
+
+       * config/tc-ns32k.c (fix_new_ns32k_exp): Get reloc type
+       differently for BFD_ASSEMBLER.
+
+       * config/tc-ns32k.c (md_estimate_size_before_relax): Get reloc
+       type differently for BFD_ASSEMBLER.
+
+       * config/tc-ns32k.c (md_create_long_jump): Size of opcode is one
+       not 2.
+
+       * config/tc-ns32k.c (md_convert_frag): Code for the BFD_ASSEMBLER
+       case. Also use smart md_pcrel_adjust function.
+
+       * config/tc-ns32k.c (md_apply_fix): Code for the BFD_ASSEMBLER
+       case. Also use smart md_fix_pcrel_adjust function.
+
+       * config/tc-ns32k.c (md_fix_pcrel_adjust): New function which can
+       find offset from opcode to operand even if in another frag
+       and in the presence of relaxing.
+
+       * config/tc-ns32k.c (md_pcrel_adjust): New function which can
+       find offset from opcode to operand even if in another frag
+       and in the presence of relaxing.
+
+       * config/tc-ns32k.c (md_number_to_disp): Check ranges properly.
+
+       * config/tc-ns32k.c (md_atof): use atof_ieee instead of special
+       atof_ns32k.
+
+       * config/tc-ns32k.c (reloc): New (static) function for
+       BFD_ASSEMBLER.
+
+       * config/tc-ns32k.c (convert_iif): More correct pc relative code.
+       md_relax must be able to find opcode address even if in another frag.
+
+       * config/tc-ns32k.c: More extensive comments.
+
+       * config/tc-ns32k.c (encode_operand): Support new operand classes I
+       and Z. Drop Q.
+
+       * config/tc-ns32k.c (fix_new_ns32k_exp): new function and
+       corresponding prototype.
+
+       * config/tc-ns32k.c: make 32532 default machine instead of 32032.
+
+       * config/tc-ns32k.c: include opcode/ns32k.h after as.h
+
+       * aout_gnu.h: r_disp needs to be 2 bits for TC_NS32K
+
+       * write.h: fx_im_disp needs to be 2 bits big for TC_NS32K
+
+       * write.c (relax_segment): Use TC_PCREL_ADJUST macro (if defined)
+       instead of adding pcrel_adjust.
+
+       * write.c (write_object_file): Adjust to_addr for the
+       BROKEN_DOT_WORD feature for the BFD_ASSEMBLER case.
+
+       * write.c (write_object_file): Use TC_CONS_FIX_NEW if it is defined.
+
+       * write.c (write_contents): Add code (currently if
+       BFD_FAST_SECTION_FILL is defined) to make large fills a lot faster.
+
+       * configure.in: Remove ns32k from special FP list. All the ns32k
+       series use ieee float.
+
+       * configure.in: Add ns32k-pc532-mach and ns32k-pc532-netbsd targets
+
+       * as.h: include expr.h before targ-env.h. Some target dependent file
+       want to use expr structures.

        * config/tc-m68k.c (m68k_ip): Change rp to be a const pointer.
