(UNW_ARCH_OBJ): New macro.
(unw_proc_info_t): New type.
(unw_accessors): Replace acquire_unwind_info and release_unwind_info callbacks
with find_proc_info callback. Change remaining prototypes to take
address-space pointer as the first argument.
(unw_get_accessors): New routine.
(unw_get_proc_info): New routine.
(unw_regname): Make it an UNW_ARCH_OBJ.
(unw_find_dynamic_proc_info): New routine.
(Logical change 1.29)
(unw_addr_space_t): New type.
(unw_accessors_t): Remove "arg" member.
(unw_local_addr_space): New variable.
(unw_create_addr_space): New function.
(unw_destroy_addr_space): Ditto.
(unw_init_remote): Take address-space and accessor-argument pointer instead of
accessor structure as argument.
(unw_set_caching_policy): Take address-space as first argument.
(unw_flush_cache): Take address space and address-range (lo & hi) arguments.
(Logical change 1.27)
various other types and constants based on it.
(unw_error_t): A UNW_EINVAL, UNW_EBADVERSION, and UNW_ENOINFO.
(unw_frame_regnum_t): Instead of hardcoding the numbers for the
well-known frame registers, use the architecture-specific
(target-dependent) values instead.
(Logical change 1.5)
(ia64_regnum_t): Define well-known frame registers here and add
TDEP-aliases for use by libunwind.h.
(unw_ia64_table_t): Use unw_tdep_word_t instead of unw_word_t so this
file can be included by libunwind.h.
Change type of "array" member to void *. On OSes that support
ILP32, it may point to a 32-bit unwind table.
(Logical change 1.5)
