Tue May 9 17:01:38 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* config.bfd: Add little endian PowerPC support.
* configure.in: Ditto.
* targets.c: Ditto.
* config/ppcle-elf.mt: New file, for little endian PowerPC
support.
* config/ppc-elf.mt: Add little endian powerpc to the BFD
selection vectors.
* elf32-ppc.c (ppc_elf_merge_private_bfd_data): Complain if
linking a different endian object than we expect.
(TARGET_LITTLE_SYM, TARGET_LITTLE_NAME): Define, to provide little
endian support.
Tue May 2 16:32:24 1995 Jeff Law (law@snake.cs.utah.edu)
* config.bfd (hppa*-*-lites*): Treat just like hppa*-*-*elf*.
Tue Apr 25 19:38:43 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
* coffgen.c (make_a_section_from_file): Initialize lma same as
vma.
