+ * 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

+ (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.
