(_U_ia64_uc_addr): New function.
(access_reg): Use uc_addr() to calculate ucontext address. Use uc->sc_rbs_base
when accessing ar.bsp or ar.bspstore (see comments for unw_init_local()).
(access_fpreg): Ditto.
(ia64_local_resume): Renamed from resume(). Read NaT bits via ia64_access_reg().
Call abort() instead of fprintf() when encountering a signal trampoline.
(unw_init_local): Initialize uc->sc_rbs_base to the bsp value of the current function.
For UNW_LOCAL_ONLY case, just initialize c->uc and then call
common_init() to do the remaining initialization. For the general case,
just initialize the accessor and then also call common_init().
(Logical change 1.8)
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)
