David Mosberger <davidm@hpl.hp.com>
* ia64-tdep.c (KERNEL_START): New macro.
(ia64_pseudo_register_read): Fix code to use libunwind to properly
get the rse registers.
(ia64_frame_this_id): Mark outermost frame with null frame id.
(ia64_sigtramp_frame_prev_register): Fix up debug output.
(ia64_access_rse_reg): New accessor function.
(ia64_access_mem): Add special logic for accessing the
kernel's unwind table.
(getunwind_table): Fix for corefiles.
(get_kernel_table): Fix to handle vDSO.
(ia64_libunwind_frame_this_id): Check for null frame id and
don't unwind past pc value of 0. Fix debugging output.
(ia64_libunwind_sigtramp_frame_this_id): New function.
(ia64_libunwind_sigtramp_frame_prev_register): Ditto.
(ia64_libunwind_sigtramp_frame_sniffer): Ditto.
(ia64_libunwind_sigtramp_frame_unwind): New unwinder.
(ia64_unw_rse_accessors): New libunwind accessors.
(ia64_libunwind_descr): Add ia64_unw_rse_accessors.
(ia64_gdbarch_init)[HAVE_LIBUNWIND_IA64_H]: Use
ia64_libunwind_sigtramp_frame_sniffer instead of
ia64_sigtramp_frame_sniffer.
* libunwind-frame.c (libunwind_frame_set_descr): Add
special register accessors.
(libunwind_frame_cache): Add special logic to check for
0 pc value. Check for a signal trampoline frame.
(libunwind_frame_this_id): Check if libunwind_frame_cache
returns NULL.
(libunwind_frame_prev_register): Check for NULL cache.
(libunwind_frame_base_address): Ditto.
(libunwind_sigtramp_frame_sniffer): New function.
(libunwind_get_reg_special): Ditto.
(libunwind_load): Add unw_is_signal_frame support.
* libunwind-frame.h (struct libunwind_descr): Add special_accessors
field.
(libunwind_sigtramp_frame_sniffer): New prototype.
(libunwind_get_reg_special): Ditto.
