	* som.c (som_begin_writing): New approach at dealing with holes
	in executables left by the HP linker.  Does not rely on subspace
	alignments as subspaces are *NOT* guaranteed to be properly

Sun Mar 20 09:24:36 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

	* bfd/som.c (som_begin_writing): Fix thinko (off by one error).

	* som.c (bfd_section_from_som_symbol): Only to do the value
	comparison for function symbols within executables.

	* som.c (bfd_section_from_som_symbol): Renamed from
	som_section_from_subspace_index.  Pass in a native SOM symbol.
	For executables, iterate through the sections to find out
	which contains the symbol's address rather than using the
	symbol_info field.  (symbol_info has a different meaning for
	dynamicly linked executables.)

	* trad-core.c (trad_unix_core_file_p): Don't pass abfd to
	bfd_zmalloc.

	* som.c (som_begin_writing): Fix braino (one call to align
	space/subspace data was done unconditionally rather than

	make HPUX kernel happy.  Fixes strip/objcopy for shared
	executables.

Sat Mar 19 07:06:59 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

	* som.c (som_begin_writing): Account for alignment needs of
	subspaces too when writing executables.  Never request a negative

Fri Mar 18 19:12:47 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

	* trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not

	* bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
	* libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.

	to be copied from input section to output section during
	objcopy or strip.
	(som_section_data_struct): Remove several fields now in
	som_copyable_section_data_struct.  Make the space and 
	subspace dictionaries be pointers (to save space when
	only reading objects).

	* som.c (bfd_som_set_section_attributes): Now returns a boolean;
	some references changed.  Allocate a copyable data stucture if
	none exists.  Store info into the copyable data structure.
	(bfd_som_set_subsection_attributes): Likewise.
	(som_is_space, som_is_subspace, som_is_container): New functions.
	Use these instead of directly accessing private data.

	Fill in some fields in the space/subspace headers from the
	copyable data.
	(som_bfd_copy_private_section_data): Only copy the stuff
	that we really need to make objcopy and strip work.  Allocate
	the copy_data structure for the output bfd before copying.

	* som.h (struct som_exec_data): New structure to hold exec
	info that must be preserved when running objcopy/strip.
	(struct somdata): Add new "exec_data" field and accessor
	macro.  Add some comments on how the various fields are used.
	(som_section_data_struct): Make is_space and is_subspace bitfields.
	Delete unused subspace_index.  All references now use the
	target_index field within the section structure itself.

	* som.c (make_unique_section): Delete unused declaration.
	(som_bfd_copy_private_bfd_data): New function.
	(som_object_setup): Allocate space for and save exec information
	that needs to be copied during objcopy/strip.
	(som_mkobject): Do not allocate space for a file header here.
	It is not used when only reading SOM objects.
	(som_prep_headers): Allocate space for and attach a file header
	to the output bfd.  For executables, use the saved system_id
	value rather than trying to guess the right value.  Do not abort
	wwhen setting file_hdr->entry* for executables.
	(som_begin_writing): For executables, set the exec_entry and
	exec_flags fields.
	(som_copy_private_backend_section_data): Always return a value.

	* libhppa.h (PA_PAGESIZE): Define.

	* som.c (SOM_ALIGN): Define.
	(som_begin_writing): If writing an executable, initialize all
	fields in the exec header to zero.  Update fields in the exec
	header as sizes of loadable subspaces are computed.  Carefully
	preserve alignments when building executables.  Actually write the
	exec after all the fields are filled in.

        * Better long-filename handling.  Reads SOM ABI compliant extended
	names, but doesn't quite write compliant extended names yet.
	* som.c (som_slurp_extended_name_table): Delete function.  The
	generic code will handle things correctly.
	(som_slurp_armap): Seek to the beginning of the next member.
	(normalize): New function.
	(som_bfd_ar_write_symbol_stuff): Take the size of the extended
	name table into account when computing the file offsets in the
	SOM dictionary.  Make sure to align to an even boundary.
	(som_write_armap): Initialize the checksum to zero.
	(ar_maxchars): Fix.  Opps.

Fri Mar 18 20:35:24 1994  Ken Raeburn  (raeburn@cujo.cygnus.com)

	machine.  Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

	* bfd-in2.h: Regenerated.

	* trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
	this was also named trad_unix_bfd_copy_private_bfd_data.

Thu Mar 17 10:37:07 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

	* aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
	elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
	returns NULL, it is not an error.  It's possible that some of
	these checks are not necessary (because the size can never be
	zero), but putting in the checks is the conservative thing to do
	in light of the fact that some of these malloc calls replaced
	unchecked alloca calls, in which a zero argument would work fine.

Thu Mar 17 11:44:45 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

	* osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
	duplicate definition.
	(osf_core_bfd_is_local_label): Define.

	* reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
	if malloc (0) fails.  bfd_canonicalize_reloc returning 0 is not a
	failure indication, it merely means there are no relocs.

	* elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
	after NAME, since SunOS /bin/cc can't handle it.

Wed Mar 16 16:43:33 1994  David J. Mackenzie  (djm@thepub.cygnus.com)

	* netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
	From sukes@glue.umd.edu (Tasuki Hirata).

Wed Mar 16 07:55:54 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)

	* aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
	all that convoluted stuff with NAME, CAT3, etc.  The convoluted
	stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).

Wed Mar 16 00:02:05 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

	* som.c (som_prep_for_fixups): Detect section symbols based
	on either the lack of private data or the symbol flags.  Do not
	munge section symbol names anymore -- they no longer confuse GDB.
	(som_begin_writing): Leave space for an exec header if writing
	an executable.
	(som_slurp_symbol_table): Recognize both forms of section symbol
	names "L$0\002" and "$<FOO>$".  Change the name of "L$0\002"
	section symbols to be the name of the section they represent.
	Debugging  symbols begin with "L$0\001", not just "L$".

Tue Mar 15 22:58:28 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)

	* bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.

	and bfd_is_local_label.

	* targets.c: Add new entries to the bfd_target structure.
	
	* bfd.c (bfd_copy_private_bfd_data): New definition.

	* section.c (bfd_copy_private_section_data): New definition.

	* aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
	MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
	(MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
	MY_bfd_seclet_link): Define.
	(MY_bfd_reloc_type_lookup): Rename from
	MY_reloc_howto_type_lookup.
	(MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
	(MY(vec)): Use JUMP_TABLE rather than listing functions.
	* hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
	MY_canonicalize_reloc, MY_write_object_contents): Don't define in
	terms of MY, because that causes a recusive invocation of CAT when
	expanded within JUMP_TABLE, and ANSI compilers don't expand
	recursive macros.
	* mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
	MY_reloc_howto_type_lookup, and don't define in terms of MY.
	(MY_canonicalize_reloc): Don't define in terms of MY.
	(aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
	than listing functions.

	* config.bfd: Use m68k-elf for m68*-*-sysv4*.
