	From Jeff Law and Pete Hoogenboom at Utah:

	* elf32-hppa.h (hppa_elf_stub_finish): Add prototype.
	(ELF32_HPPA_R_ARG_RELOC): Renamed without the ELF32 prefix
	and moved into libhppa.h.  All references changed.
	(ELF32_HPPA_R_CONSTANT, ELF32_HPPA_R_ADDEND): Likewise.
	(get_opcode and opcode defines): Move into libhppa.h
	* elf32-hppa.c (hppa_elf_insn2fmt): Rename and move info
	libhppa.h.
	* libhppa.h (HPPA_R_*): Moved here.  Reformatted slightly to make
	for easier reading.
	(get_opcode): Moved here.  FIXME! this really should be a C function
	inside the opcode library!
	(bfd_hppa_insn2fmt): Likewise.

	* targets.c (target_vector): Enable elf32-hppa vector.

	* elf32-hppa.c (hppa_elf_get_section_contents): Add new comments
	and clarify existing comments.  Do not use DEFUN to declare this
	function.  Fix numerous indention problems.  Correctly handle cases
	where symbol extension section may need to be read from disk, 
	read from memory, or built then read from memory.

	* elf32-hppa.h: Reformat with gnu-indent and hand fix numerous
	formatting and indention problems gnu-indent can not handle.
	Clarify some comments about relocation types.  Comment basic
	relocation "classes".  Group PARAM declarations together.
	(HPPA_SXT_{NULL, SYMNDX, RG_RELOC}): Make members of a new 
	enumerated type rather than #defines.

Tue Oct 26 02:40:46 1993  Stu Grossman  (grossman at cygnus.com)

	* som.c (hppa_object_setup):  Set SEC_CODE for .text section so
	that GDB can figure out text_start and text_end.

Mon Oct 25 16:05:23 1993  Ian Lance Taylor  ([e-mail])

	Fix up warnings from gcc -Wall:
	* coffgen.c (coff_print_symbol): Use %lx and cast n_value to
	unsigned long.  Use %ld for tagndx.  Use %lx for offset + vma and
	cast it to unsigned long.
	* ecoff.c (ecoff_emit_aggregate): Use %ld.	
	(ecoff_print_symbol): Use %ld, and cast indx and sym_base to long.
	* coffcode.h (dummy_reloc16_estimate): Specify return type.

	* libbfd.c (bfd_write): If not everything is written out, set
	bfd_error to system_call_error.  If the return value is
	non-negative, set errno to ENOSPC (if ENOSPC is defined).
	(bfd_seek): If the seek fails, set bfd_error to system_call_error.
	(bfd_generic_set_section_contents): For a bad offset + count, set
	bfd_error to bad_value.
	* seclet.c (rel): Don't abort.  Instead, return false.

Mon Oct 25 09:59:37 1993  Ken Raeburn  ([e-mail])

	* aoutx.h (reloc_type_lookup): Handle BFD_RELOC_SPARC_WDISP22.

Fri Oct 22 20:35:54 1993  david d `zoo' zuhn  ([e-mail])

	* config.bfd: handle mips*-* instead of mips-*, use mips*el
	  instead of mips-*-*l

Fri Oct 22 14:03:33 1993  Mark Eichin  ([e-mail])

	* m68k-lynx.mt, i386-lynx.mt (TDEFINES): set
	FPRINTF_ALREADY_DECLARED because the objdump.c declaration of
	fprintf collides with the native one.

Fri Oct 22 11:50:25 1993  Ian Lance Taylor  ([e-mail])

	* targets.c (target_vector): Enable MIPS ELF vectors.

Fri Oct 22 07:51:51 1993  Jim Kingdon  ([e-mail])

	* config.bfd: Use bigmips for mips-sony-bsd*.

	* configure.host, config.bfd: Add * to end of all OS names.

Thu Oct 21 12:16:26 1993  Ken Raeburn  ([e-mail])

	* elfcode.h (FILE_ALIGN): Renamed from EALIGN, to avoid conflict
	with Ultrix header files.

	* som.h (struct som_section_data_struct): Renamed from
	som_section_data to avoid conflict with macro by that name.

	Changes from Jeff Law and Peter Hoogenboom at Utah:

	* elf32-hppa.c (hppa_elf_reloc):  Target register for a 'jump
	in delay slot' optimization in combination with a long call
	stub should always be r31.

	* elf32-hppa.c: (hppa_elf_relocate_insn): To be consistent
	across all relocation types, retrieve instruction addends from
	the relocation entry rather than from the instruction itself.

	* elf32-hppa.c: (hppa_elf_relocate_insn): Fix a relocation
	error that only occurred when the addend of an 'addil' or
	'ldil' was larger than 21 bits and very close to a 2K byte
	boundary.

	* elf32-hppa.c: (hppa_elf_reloc):  Handle the optimization in
	which a jump is placed in the delay slot of a function call.
	The jump was being accomplished via an adjustment to the
	return pointer.  This optimization would break the long call
	stub code, if there was any.

	* elf32-hppa.c: (hppa_elf_build_long_branch_stub): Corrections
	to long branch stubs to avoid use of general register 2.

	* hppa_stubs.h: New stub instructions.

	* elfcode.h: Declare bfd_elf_find_section.

	* som.h (som_section_data): Add new "subspace_index" field.

	* som.c (setup_sections): Save the original SOM subspace index
	in the BFD section associated with that subspace.  
	(som_get_symtab_upper_bound): Implement.
	(som_get_symtab): Implement.
	(som_print_symbol): Implement.
	(som_slurp_string_table): New function to read a string table
	from a SOM object file.
	(som_section_from_subspace_index): New function to return the
	section which corresponds to a SOM subspace index.
	(som_slurp_symbol_table): New function to read the symbol
	table from a SOM object file.
	(som_make_empty_symbol): Check for errors from bfd_zalloc.
	(som_new_section_hook): Initialize subspace_index field to
	-1 instead of 0.

	* som.c (som_object_setup): Fix polarity of test to set HAS_RELOC.
	Set EXEC_P for executables.
	(setup_sections): Correctly identify when a section has
	relocations.
	(log2): New function.
	(setup_sections): Correctly convert between SOM alignments and BFD
	alignments.

	* som.c (setup_sections): Do not set SEC_ALLOC or SEC_LOAD
	for sections which correspond to SOM spaces, doing so confuses
	many utilities.  Set assorted SEC_* flags for SOM subspaces
	which correspond to BFD sections.

	* elf32-hppa.c: (elf32_hppa_backend_fake_sections): The stab
	string table should have sh_type == SHT_STRTAB.  Add
	processing to make it so.

	* elfcode.h: (bfd_section_from_shdr): String tables (other
	than .strtab) were not getting the file offsets recorded, so
	they could not be read from disk.

	* elfcode.h: (elf_make_sections):  Leave the sh_addr field of
	the section header and the vma field of a section at 0 if the
	section is not part of the program execution image. (e.g.,
	.stab)

	* som.[hc]: Change target vector prefix from "hppa" to "som".
	Consistently use obj_som prefix to access fields in backend data
	structures.  Fix all callers/references.

	* som.h: Do not include files only needed for core file reading here.
	Include a.out for both HOST_HPPAHPUX and HOST_HPPABSD.  Delete
	forward structure declarations, they are unnecessary.
	(struct somdata): Delete aux_hdr, and hp_symbol_entry_size fields.
	Change "symbols" to "symtab".  Add "stringtab" and "reloc_filepos"
	fields for future use.  Change obj_som_* macros as appropriate.
	(som_section_data): New structure to keep SOM specific information
	about BFD sections (for future use).

	* som.c: Provide PARAMS declarations for all functions currently
	in this file.
	(struct container): Delete unwanted structure definition.
	(som_object_setup): Add comments.  Use som_mkobject to allocate
	SOM specific information in the BFD; use information from the
	file and (possibly empty) auxiliary headers to initialize this
	information.  Delete redundant bfd_get_symcount (abfd) "calls".
	(setup_sections): Return type is now boolean, fix return statements.
	"Fix" handling of BSS like subspaces in the computation of the
	containing space's size.  If the subspace has relocations, set the
	appropriate BFD section flags and record the index into and the
	size of the fixup stream.  Always return a value.
	(som_object_p): Set bfd_error appropriately if errors are detected
	from bfd_{read,seek} functions.  Handle EXECLIBMAGIC type files.
	Do not try to read a non-existant auxiliary header.
	(som_mkobject): Flesh out.
	(som_section_hook): Allocate space to hold SOM specific information
	about sections.

Thu Oct 21 12:41:34 1993  Jim Kingdon  ([e-mail])

	gcc -Wall lint:
	* coff-h8300.c, coffcode.h: Change shrink parameter
	in *_reloc16_estimate to unsigned to match prototype.
	* archive.c: Avoid "/*" in comment.

Thu Oct 21 13:05:16 1993  Ian Lance Taylor  ([e-mail])

	* dep-in.sed: Create our own line breaks for a more aesthetic
	Makefile.
	* Makefile.in: Rebuilt dependencies.

	* elf32-mips.c: Include "seclet.h".
	(mips_elf_fake_sections): Force size of .reginfo section to sizeof
	Elf32_External_RegInfo.
	(mips_elf_seclet_link): New function.  Link the .reginfo section
	specially, and pass everything else to the generic routine.
	(bfd_elf32_bfd_seclet_link): Define macro.
	* elf32-target.h: If bfd_elf32_bfd_seclet_link is already defined,
	don't override it.

Wed Oct 20 12:22:37 1993  Ian Lance Taylor  ([e-mail])

	* libnlm.h (nlm_backend_data): Added signature field.
	(nlm_signature): New macro.
	* nlmcode.h (nlm_object_p, nlm_write_object_contents): Use the NLM
	signature from the backend rather than the constant NLM_SIGNATURE.
	* nlm32-i386.c (nlm32_i386_backend): Initialize signature field.

	* aoutf1.h (MACHTYPE_OK): Accept M_UNKNOWN.
	(NAME(sunos,set_arch_mach)): Treat M_UNKNOWN as 68000, not 68020.

Wed Oct 20 10:28:27 1993  Jim Kingdon  ([e-mail])

Wed Oct 20 10:10:07 1993  Ken Raeburn  ([e-mail])

	* Makefile.in (HFILES): New variable, for use in "make dep".
	(.dep): Depend on $(CFILES) and $(HFILES).  Delete .dep1 and
	remake it, so that "$?" is complete.
	(.dep1): Don't need to remove .dep1 first.
	(dep.sed): Depend on config.status, not Makefile.
	(CFILES): Add nlm.c.

Tue Oct 19 15:26:26 1993  Ian Lance Taylor  ([e-mail])

	* coff-alpha.c: Implemented reloc handling for the linker, made
	various other related changes.
	* libecoff.h (ecoff_backend_data): Added rdata_in_text field.
	Renamed finish_reloc to adjust_reloc_in.  Added adjust_reloc_out
	field.
	(ecoff_bfd_get_relocated_section_contents): Don't define.

	.rdata section in text segment, not data segment.  Put .pdata
	section in text segment.
	(ecoff_write_object_contents): Likewise.  Also, call
	adjust_reloc_out, and handle .lita, .xdata, .pdata, .fini and
	absolute sections when writing out relocs.
	* coffswap.h (coff_swap_aouthdr_out): For ALPHAECOFF, output 2 for
	bldrev field, as on Alpha OSF/1.  Padding field is now 2 bytes.

	(mips_adjust_reloc_in): Renamed from mips_finish_reloc.
	(mips_adjust_reloc_out): New function (does nothing).

	(ecoff_bfd_get_relocation_section_contents): Define to be
	bfd_generic_get_relocated_section_contents.

	* reloc.c (bfd_perform_relocation): Added casts to avoid Alpha
