ede4eed483 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.

80425e6c82 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
cruft (like the #pragma alloca for AIX).
	In addition to that problem, the C alloca calls xmalloc, which
	means checking for being out of memory can't work right.  The
	following changes remove all uses of alloca from BFD.
	* hosts/solaris2.h: Remove alloca cruft.

6e58a4e5db * elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
unused symbols argument.

        * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
        than asymbol * for original target symbol.  All callers changed.
        Set reloc->sym_ptr_ptr appropriately.

e08b9ad7a1 * elf32-hppa.c: Second half of major cleanup. More comments,
PARAMize and staticize rest of functions.  Delete unused
	functions.  Delete unused/unnecessary arguments to some functions.
	Group static vars together.  Abort for bad errors until we have
	error code propogation working.  Work on spacing and indention.
	Add FIXMEs for unresolved problems.  Use enums rather than
	#defines for lots of things.  Merge two functions which build
	linker stubs into a single function (so they can easily share a
	ton of common code).

        static vars together.  Collapse common case statements together
        in many places.  Use default case when possible instead of listing
        each case separately.  Abort for bad errors until we get error
        code propogation working.  Work on spacing and indention problems.
        Add FIXMEs for some unresolved problems.  Delete hopelessly broken

and moved into libhppa.h.  All references changed.
(ELF32_HPPA_R_CONSTANT, ELF32_HPPA_R_ADDEND): 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

now.
