* breakpoint.c (until_break_command_continuation): Add
the 'error' parameter. Directly delete the breakoint as
opposed to running cleanups.

started the target in async mode.

declaration.

* exceptions.c (throw_exception): Don't call do_exec_cleanups.
* inf-loop.c (inferior_event_handler): Instead of calling
discard_all_continuations, use do_all_continuations with 1 as
'error' parameter. Pass 0 as 'error' parameter in existing uses
of discard_all_continuations.

cleanups.
(step_once): Install continuation only after resuming the target.
(step_1_continuation): Disable longjmp breakpoint on error.

the finish breakpoint directly, do not use cleanups.

continuation. For sync case, immediately run them.
(attach_command_continuation): Add the error parameter.
* infrun.c (fetch_inferior_event): Do not use exec cleanups to
remove step_resume_breakpoint -- adjust delete it directly.
* interps.c (interp_set): Adjust call to do_all_continations.

do exec cleanups.
* mi/mi-main.c (mi_cmd_target_select): Do not do exec
cleanups.

logic. Do no use exec cleanup.

value based on prologue analysis. Fix the bugs preventing WS and
AR4-AR7/A11 registers from getting right values for intermediate frames,
whose registers have been already spilled.
(xtensa_frame_prev_register): Fix WS register value. Use are_number
and arreg_number appropriately.
(xtensa_gdbarch_init): Set solib_svr4_fetch_link_map_offsets to
svr4_ilp32_fetch_link_map_offsets.
