an improved version of some code extracted from skip_prologue().
        (skip_prologue): Use store_param_on_stack_p() to detect
        instructions saving a parameter on the stack. Detect when r0
        is used to save a parameter.
        Do not mark "li rx, SIMM" instructions as part of the prologue,
        unless the following instruction is also part of the prologue.

	* infrun.c (handle_inferior_event): Simplify
	STEP_OVER_UNDEBUGGABLE.

	* infrun.c (handle_step_into_function): Delete function.
	(handle_inferior_event): Inline calls to
	handle_step_into_function.

* regcache.c (struct regcache_descr): fix comment spelling.

        Fixes a link link failure.

        error that was causing the build to fail.

        * Makefile.in (aix-thread.o): Add dependency on gdb_string.h.

(fetch_regs_user_thread, fetch_regs_kernel_thread)
(store_regs_user_thread, store_regs_kernel_thread): Use
ppc_num_gprs and ppc_num_fprs instead of '32' and '31'.
* ppc-linux-nat.c (fill_gregset): Same.
* ppc-linux-tdep.c (ppc_linux_supply_gregset)
(ppc_linux_sigtramp_cache): Same.
* ppcnbsd-tdep.c (ppcnbsd_supply_reg, ppcnbsd_fill_reg)
(ppcnbsd_sigtramp_cache_init): Same.
* rs6000-nat.c (fetch_core_registers): Same.
* rs6000-tdep.c (ppc_supply_gregset, ppc_collect_gregset)
(rs6000_frame_cache): Same.

	* infrun.c (handle_inferior_event): Check for
	STEP_OVER_UNDEBUGGABLE after signal trampolines and function
	calls.  Update comments.

(store_regs_user_thread): Use tdep->ppc_gp0_regnum, instead
of assuming that the gprs are numbered starting with zero.
* ppc-linux-nat.c (fill_gregset): Same.
* ppc-linux-tdep.c (ppc_linux_supply_gregset): Same.
* ppcnbsd-nat.c (getregs_supplies): Same.
* ppcnbsd-tdep.c (ppcnbsd_supply_reg, ppcnbsd_fill_reg): Same.
* rs6000-nat.c (fetch_core_registers): Same.
* rs6000-tdep.c (ppc_supply_gregset, ppc_collect_gregset): Same.

        * tracepoint.c (scope_info): Add handling for LOC_COMPUTED,
        LOC_COMPUTED_ARG, and LOC_INDIRECT.

	* infrun.c (handle_inferior_event): Use frame_unwind_id.
