b4a52cc9cc Big restructuring of ia64 code: the code generated for UNW_LOCAL_ONLY should be
more or less unchanged, but for the generic version, the save-location has been
expanded from a single word to two words.  This is needed to accommodate 32-bit
targets and targets which require accessing the ucontext_t structure via uc_access(3).
Overall, this should be like a big no-op for Linux (apart from slowing down
the generic case a bit).  However, at the moment, unw_resume() has not been updated
for the generic case (UNW_LOCAL_ONLY works fine though).

(update_frame_state): For cursor's with a non-zero abi_marker, do special
	Linux or HP-UX sigtramp handling as appropriate.
	Clear abi_marker instead of is_signal_frame.

8bf1568dbf (script_new): Clear abi_marker to 0.
(emit_nat_info): For registers saved in a general-register, use IA64_INSN_SET_REG
	instead of IA64_INSN_SET.
	Set insn.dst to register number, instead of unw.preg_index[i].
(compile_reg): Set val directly to register number, instead of unw.preg_index[i].
	Use IA64_INSN_INC_PSP instead of IA64_INSN_ADD to pop a fixed stack frame.
(build_script): Handle signal-frames by directly copying abi_marker, rather than
	emitting an IA64_INSN_SET instruction.
(run_script): Copy abi_marker into cursor.  Rather than updating a word, update
	a save-location.  Only exceptions are IA64_INSN_INC_PSP and
	IA64_INSN_LOAD_PSP.

ed67c3edb7 (ia64_pregnum): Rename IA64_REG_RP to IA64_REG_IP.
(ia64_loc_t): New type.  For UNW_LOCAL_ONLY, it's a single word, as before.
	For the generic case, it's a 2-word structure.  This provides enough
	space to encode all necessary info both for 32-bit targets (which require
	only 4-byte aligned addresses) and for targets which are limited to
	accessing ucontext_t values via uc_access(3).
(ABI_MARKER_LINUX_SIGTRAMP): New macro.
(ABI_MARKER_HP_UX_SIGTRAMP): New macro.
(struct cursor): Consolidate bsp_loc, bspstore_loc, pfs_loc, rnat_loc, ip_loc,
	pri_unat_loc, unat_loc, pr_loc, lc_loc, fpsr_loc, r4-r7_loc,
	b1-b5_loc, f2-f7_loc, and fr_loc[] into loc[] array.  Note that
	there is now a separate PSP-loc (loc[IA64_REG_PSP]) in addition
	to the cached psp value.
	Rename sigcontext_loc to sigcontext_addr.
	Remove is_signal_frame memeber and add abi_marker member instead.
	Change type of rbs_area[].rnat_loc to ia64_loc_t.
(struct ia64_global_unwind_state): Remove preg_index[] array.
