(Almost) the last patch for HP-UX IA64 support.

- Subject: (Almost) the last patch for HP-UX IA64 support.
- Reply-to: sje at cup dot hp dot com
This patch is the last change I have for HP-UX IA64 support except for
libtool changes and a possible change to bfd/elf.c that is probably
going to need some discussion before it can be approved. I am hoping we
might update to the latest libtools at some time (before 2.12?) because
this already has HP-UX IA64 support in it and then I won't need a patch
for the version of libtools in binutils.
Here is a patch to put an IA64 HP-UX target in configure.in and
to add gas support.

2002-01-07 Steve Ellcey <sje@cup.hp.com>
* configure.in (ia64*-*-hpux*): New target for IA64 HP-UX,
ld and gdb are not supported.
* configure: Regenerate
* gas/config/tc-ia64.h (MD_FLAGS_DEFAULT): New Macro for
setting default md.flags.
(SHT_INIT_ARRAY): New elf special section used by HP-UX.
(SHT_FINI_ARRAY): New elf special section used by HP-UX.
* gas/config/tc-ia64.c (setup_unwind_header): Add support
for 32 bit unwind info blocks.
(generate_unwind_image): Add support for different types
of unwind images (32 bits and/or big-endian).
(ia64_init): Use MD_FLAGS_DEFAULT to set md.flags.
(ia64_target_format): Add support for hpux target formats.
(ia64_gen_real_reloc_type): Add support for FUNC_IPLT_RELOC.
* gas/config/obj-elf.c (obj_elf_section_type): Add support
for SHT_INIT_ARRAY and SHT_FINI_ARRAY elf section types.
