unconditionally returns -UNW_EINVAL.
(access_reg): IP is now read via UNW_IA64_IP (instead of
UNW_IA64_BR+0). CFM is now read via UNW_IA64_CFM
instead of UNW_IA64_AR_PFS. For UNW_IA64_AR_BSP
(and UNW_IA64_AR_BSPSTORE), adjust the pointer so
that it points to the first stacked register in
the current frame.
(resume): "rp_loc" has been renamed to "ip_loc".
(unw_init_local): Add an #error directive to prevent compilation
with UNW_LOCAL_ONLY until this case has been implemented.
(Logical change 1.5)
(get_kernel_table): Return -UNW_ENOMEM if unable to allocate buffer
for kernel's unwind info. Initialize the start and end
members in unw_ia64_table_t.
(callback): Initialize the start and end members.
(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)
cfm_loc with UNW_IA64_CFM. Initialize bspstore_loc with
UNW_IA64_AR_BSPSTORE. Renamem rp_loc to ip_loc and initialize
with UNW_IA64_IP. Initialized the cached values of
PR and IP. Initialize sp and psp to value in UNW_IA64_SP.
Initialize exception handling args by reading the corresponding
scratch registers (r15-r18). If the read fails, initialize
with 0. Finish by calling ia64_get_proc_info() instead of
ia64_get_frame_state().
