handle MIPS specific sections.

	(elf_gp, elf_gp_size): New accessor macros.
	* elfcode.h: Removed a number of unused local variables.

ee8cb54804 Deleted some fields of elf*_symbol_type and elf_obj_tdata that were getting
set but not used.  Merged elf*_symbol_type into a single elf_symbol_type.

e2a422b84c Merged in changes from Jeff Law and Pete Hoogenboom at Utah for PA ELF
support.  Compiles, not particularly well tested.  See ChangeLog for details.

d24928c05b * elfcode.h (elf_build_phdrs): Unused function deleted.
(bfd_shdr_from_section): Ditto.
(write_relocs): Don't change section contents for addend.
(elf_locate_sh): Return type is now always elf_internal_shdr, since the other
types were really aliases for this type anyways.  Don't compile this function,
since it is static and doesn't appear to be used in this file.
(sym_is_global): Return non-zero for weak symbols.  Abort if sec ptr is null.
(swap_out_syms): Reorder tests so function symbols can be weak.
(elf_slurp_symbol_table): Don't use BSF_EXPORT.
(elf_slurp_reloca_table): Make RELOC_PROCESSING section smaller by
extracting out some common code.  Abort if BFD section symbol has null name.
(elf_slurp_reloc_table): Translate ELF section symbols into BFD section
symbols.  Don't read section contents to fill in addend field.

* Merged from OSF:

* libelf.h (struct Elf_Sym_Extra): New structure to contain ELF
specific information for a symbol.  Put in elf_sym_num, which
gives the external symbol number in the elf object file, since
local symbols must come before global symbols.
(elf_sym_extra): New macro.
(elf_symtab_map): Delete, in favor of using Elf_Sym_Extra.
* elfcode.h (elf_map_symbols): Use Elf_Sym_Extra to map internal
symbol number to external number.  Store the address of the
Elf_Sym_Extra field for the symbol in the udata field.
(elf_write_object_contents): Use Elf_Sym_Extra to map out symbols.

Sun Jun 20 16:30:11 1993  Michael Meissner  (meissner@osf.org)

* elfcode.h (elf_obj_tdata): Add field to count the size of the
array of pointers to section symbols.
(elf_map_symbols): Bump the max index of the section symbols so
that we don't overwrite memory.  Store the max index into the
elf_obj_tdata field.

Sat Jun 19 10:12:27 1993  Michael Meissner  (meissner@osf.org)

* elfcode.h (elf_obj_tdata): Add pointer to an array of pointers
to the section symbols we created.  Remove unused field internal_syms.
(elf_map_symbols): Fill in array of pointers to section symbols.  Only create
section symbols for sections that have SEC_ALLOC set, and have non-zero size.
(elf_symbol_from_bfd_symbol): If udata is NULL, and this is a section symbol,
look up the section in the list of section symbols, and set the udata pointer
appropriately.  Otherwise, if udata is still NULL, fail an assertion, and use
0, instead of dropping core.

153cb9ade3 * libelf.h (NAME): Provide a default definition, that's neither
for 32 bits nor for 64.

Tue Jun 15 14:38:32 1993  Michael Meissner  (meissner@osf.org)

* libelf.h (elf_hash): Change declaration to bfd_elf_hash, since
that is what is in elf.c.

d79ab07c4a * libelf.h (struct elf_backend_data): New field, maxpagesize.

	* Makefile.in (nlm.o, nlm{32,64}.o, nlm{32,64}-gen.o:  New targets.
	* bfd-in2.h (INLINE):  Defines moved here.

	* targets.c (target_vector):  Add bfd_nlm{32,64}_{big,little}_vec.
	* (libnlm.h, nlm.c, nlmcode.h, nlm{32,64}-gen.c,
	nlm{32,64}-target.h, nlm{32,64}.c, config/i386-nlm.mt):  New files
	for NLM support.

32090b8e4f * elf.c, elfcode.h, libelf.h: Serious reorganization.
Deleted `thunk' structure, merged into tdata, duplicate data eliminated.
Rearranged functions, grouping by function.
Broke up many functions in elfcode.h, re-ordered many parts of file writing
to handle unpredictable state of section relocation table as provided by
various applications.
Still needs cleanup: Merge functions back together, split out data structure
with only data that is used only when writing out object file.

* elf.c (bfd_elf_generic_reloc): New function, taken from coff-mips.c.
* elf32-sparc.c (elf_sparc_howto_table): Use it, to work around
bfd_perform_relocation lossage.

* elfcode.h (elf_new_section_hook): Do nothing for now.
	(elf_write_object_contents): Output common symbols the way ELF
	wants them.

Wed Jun 23 16:20:07 1993  Ken Raeburn  (raeburn@poseidon.cygnus.com)

	* libelf.h (struct elf_obj_tdata and associated macros): Moved
	here from elfcode.h.  A couple of size-specific structure pointers
	were changed to PTR; uses fixed appropriately.
	(elf32_symbol_type, elf64_symbol_type): Separated definitions.
	(bfd_elf_mkobject): Renamed from bfd_elf32_mkobject.
	(bfd_elf32_mkobject, bfd_elf64_mkobject, elf_mkobject): New
	temporary macros to ease name change.
	* elf.c (elf_read, elf_mkobject, elf_get_str_section,
	elf_string_from_elf_section, bfd_elf_find_section): Moved here
	from elfcode.h.
	* doc/Makefile.in (libbfd.h): Process elf.c too.
	* Makefile.in (elf.o): Note new dependencies.

	* elfcode.h: Lots of stuff moved elsewhere.  Deleted some unused
	code, tweaked some debug hooks.
	(elf_slurp_reloca_table): Translate ELF section symbols into BFD
	section symbols.

638616cafb Second try at getting elfNAME macros right.
Under ANSI C, "32_" is not a valid pp-token...

e6858d1b68 (elfNAME, ElfNAME): Use CAT directly rather than going through NAME.
