	* coff-a29k.c: do byte relocs correctly
	* coffcode.h (styp_to_sec_flags): never load INFO sections
	* seclet.c (rel): don't relocate INFO sections

Wed May 20 08:18:18 1992  Ken Raeburn  ([e-mail])

	* section.c (bfd_*_symbol, bfd_*_section): Initialize statically.
	Make the symbols unmodifiable.
	(bfd_section_init): Deleted.
	* init.c (bfd_init): Don't call bfd_section_init.

	* section.c (bfd_set_section_contents): Ensure that range to be
	written is within section boundaries.
	(bfd_get_section_contents): Likewise.  Don't bother dispatching if
	size is zero.

	* libbfd.c (bfd_xmalloc): Text of error message should be const.

	* coff-i960.c (howto_table): Deleted.
	(howto_rellong, howto_iprmed, howto_optcall): New vars;
	interesting entries from old howto_table.
	(RTYPE2HOWTO): Adjusted to use switch.
	(coff_i960_reloc_type_lookup): New function.

	* coffcode.h (coff_new_section_hook): Allocate storage for aux
	records for section symbol.
	(make_abs_section): Unused; deleted.
	(renumber_symbols): Re-order symbols so undefined symbols come
	last, as COFF format desires.
	(coff_write_symbol): Put C_FILE symbols in debug section always.
	(coff_section_symbol): New function; creates a symbol with the
	same name as a section, and sets up aux records for it.
	(coff_add_missing_symbols): New function; adds section symbols to
	symbol table if they aren't there already.  Should someday also
	add a dummy C_FILE symbol if none is present.
	(coff_write_object_contents): Add missing symbols before preparing
	symbol table to be written.
	(coff_slurp_reloc_table): Verify that symbol indices read in are
	in a reasonable range.
	* libcoff-in.h (struct coff_tdata): New field conv_table_size.
	(obj_conv_table_size): Accessor macro.

	* bout.c (b_out_reloc_type_lookup): New function.  Handles three
	reloc types on i960.

	* bfd-in.h (bfd_get_section_name): New macro.  Like
	bfd_section_name, but returns rvalue, not lvalue.
	(bfd_get_section_vma, bfd_get_section_alignment): Similar.
	(bfd_get_section_flags): Now returns rvalue.

	* reloc.c (enum bfd_reloc_code_real): Add several new values, some
	general, some specific to sparc or i960.

	* aoutx.h (set_section_contents): Set VMA for each section based
	on previous section.  If text section VMA doesn't appear to have
	been set, make a best guess from the type of file.

	* aout-target.h (MY_reloc_howto_type_lookup): Define as zero if
	not defined.
	(MY(vec)): Initialize reloc_type_lookup field.

	* aoutx.h (howto_table_*): Export as aout_#_*_howto_table.
	(bfd_error_trap, bfd_error_vector): Extern, not common.

	* aoutf1.h (sunos4_reloc_type_lookup): New function.  Handles a
	few types of relocs for sparc; will need enhancement.

	* bout.c (callj_callback): Use DEFUN macro in definition.
	* coff-i960.c (optcall_callback): Likewise.

	* targets.c (bfd_target): Added fields reloc_type_lookup and
	_bfd_make_debug_symbol.  Also minor comment changes.
	* syms.c (bfd_make_debug_symbol): New dispatching macro.
	* reloc.c (bfd_reloc_type_lookup): Take a BFD ptr as arg rather
	than arch info, and dispatch with BFD_SEND.  Callers changed.
	* archures.c (struct bfd_arch_info): Deleted field
	reloc_type_lookup.
	* cpu-*.c: Don't initialize that field.

	* bfd-in.h (enum bfd_error): Add new value "bad_value".
	* bfd.c (bfd_errmsgs): Now const; added entry for bad_value.
	(bfd_errmsg): Now returns ptr to const.
	* bfd-in.h (bfd_errmsg): Fix prototype.

	* reloc.c (bfd_generic_relax_section): Ditto.

	* section.c (Section Output doc): Improve description of use of
	output_section and output_offset.

Tue May 19 23:42:10 1992  D. V. Henkel-Wallace  ([e-mail])

	* sco-core.c: new file from net.
	* aoutx.h (translate_to_native_sym_flags): bugfix from net:
	  Now we have the hairy linker, it's possible to move symbols from
	  one section into another.  Actually make that work!

	short patches from Glenn Kasten ([e-mail])
	* target.c: enabled oasys support
	* oasys.c:  Insert . when UNDERSCORE_HACK is enabled, 
	fix problem where a relocation which crossed a modification byte
	boundary did not work. Fix problem where a relocation near the end
	of a data record did not work.
	

Tue May  5 18:11:25 1992  Steve Chamberlain  ([e-mail])

	* archive.c (bfd_slurp_coff_armap): old versions of BFD wrote
	archvie header string counts the endian way, this heuristic sees
	how big an archive string to read by trying it one way and if the
	string table is unreasonably big, trying it the other. *FIXME*.
	* opncls.c (bfd_fdopenr): can't do fdopens on VMS

Tue May  5 14:18:24 1992  Per Bothner  ([e-mail])

        * bfd-in.h: bump version to 1.96
         Major change; changed calling convention for
	 bfd_get_relocated_section_contents so that caller allocates
	 memory for section data.
	* coffcode.h (bfd_coff_get_relocated_section_contents), reloc.c,
	seclet.c, targets.c, bfd.c: reflect new convention.
	* coffcode.h (styp_to_sec_flags): if styp_flags is not a special
