Patch by H.J. Lu <hjl@gnu.ai.mit.edu>.

1997-03-18 23:08 a sun <asun@zoology.washington.edu>
* sysdeps/unix/sysv/linux/net/if_ppp.h (PPP_VERSION): Define to

already defined.
1997-03-14 23:34 Geoff Keating <geoffk@ozemail.com.au>

loader first relocates itself.
* sysdeps/powerpc/elf/start.c (__start1): Fix bug for static objects.
* sysdeps/powerpc/dl-machine.h (elf_machine_rela): Fix bugs in
jump slot relocation. Prefer relative branches (some PowerPC chips
don't predict absolute branches).
(elf_machine_runtime_setup): Simplify and correct expressions.
(RTLD_START): Fix bug changing _dl_starting_up.
* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Added. Deal with
strange Linux/PPC padding of initial stack.
1997-03-11 04:14 Geoff Keating <geoffk@ozemail.com.au>

elf_machine_runtime_setup): Flush data & instruction caches when
necessary, for 603/604 support. Add better support for large PLTs.
(elf_machine_rela): Remove relocations that wouldn't work if
anyone ever used them. Use memcpy for copy reloc, it'll be safe.
Never target branch relocations at a PLT entry.

generating PIC.
