* 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.
(ia64_elf_section_type): Add support for SHT_INIT_ARRAY and
SHT_FINI_ARRAY elf section types.
