/* Problems and other issues to resolve.
|
|
|
|
|
|
|
|
|
|
|
|
(1) BFD expects there to be some fixed number of "sections" in
|
|
|
|
|
|
the object file. I.E. there is a "section_count" variable in the
|
|
|
|
|
|
bfd structure which contains the number of sections. However, ELF
|
|
|
|
|
|
supports multiple "views" of a file. In particular, with current
|
|
|
|
|
|
implementations, executable files typically have two tables, a
|
|
|
|
|
|
program header table and a section header table, both of which
|
|
|
|
|
|
partition the executable.
|
|
|
|
|
|
|
|
|
|
|
|
In ELF-speak, the "linking view" of the file uses the section header
|
|
|
|
|
|
table to access "sections" within the file, and the "execution view"
|
|
|
|
|
|
uses the program header table to access "segments" within the file.
|
|
|
|
|
|
"Segments" typically may contain all the data from one or more
|
|
|
|
|
|
"sections".
|
|
|
|
|
|
|
|
|
|
|
|
Note that the section header table is optional in ELF executables,
|
|
|
|
|
|
but it is this information that is most useful to gdb. If the
|
|
|
|
|
|
section header table is missing, then gdb should probably try
|
|
|
|
|
|
to make do with the program header table. (FIXME)
|
|
|

(2) The code in this file is compiled twice, once in 32-bit mode and
|
|
|
|
|
|
once in 64-bit mode. More of it should be made size-independent
|
|
|
|
|
|
and moved into elf.c.
|
|
|
|
|
|
|
* 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:
Tue Jun 15 14:38:32 1993 Michael Meissner (meissner@osf.org)
* 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.

|
(3) ELF section symbols are handled rather sloppily now. This should
|
|
|
|
|
|
be cleaned up, and ELF section symbols reconciled with BFD section
|
|
|
|
|
|
symbols.

|
(4) We need a published spec for 64-bit ELF. We've got some stuff here
|
|
|
|
|
|
that we're using for SPARC V9 64-bit chips, but don't assume that
|
|
|
|
|
|
it's cast in stone.

* elfcode.h (elf_build_phdrs): Unused function deleted.

NAME(bfd_elf,link_create_dynamic_sections)
|
Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of

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

elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of

Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the

Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

* elf32-sparc.c: Include bfdlink.h.
(elf_info_to_howto): Change type of dst from Elf32_Internal_Rela
to Elf_Internal_Rela (they're the same type anyhow).
(elf_sparc_relocate_section): New function.
(elf_backend_relocate_section): Define.
* elf32-mips.c (elf_backend_collect): Define.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.
