350ae98340 (local_resume): Clear IA64_SC_FLAG_IN_SYSCALL before resuming via
sigreturn().  This is needed to ensure that all scratch-regs
	get restored.  Also add some more debug statements.

d0fddf5de8 (ia64_find_save_locs): Only call ia64_fetch_proc_info() when we really
have to (i.e., if we don't have cached info).  Otherwise,
	the unnecessary calls cause a performance regression.

b3c1bf3f75 (flush_script_cache): Drop addr_space_t argument. Initialize
hash-table, collision-chains, and hash-table in addition
	to clearing the script's IP value.  The latter wasn't nearly
	sufficient because it could cause loops on the collision
	chain...
(get_script_cache): Also lock the cache if global caching is in
	effect.  Take additional "saved_sigmaskp" argument.
	After flushing the cache, update the cache generation
	here.
(put_script_cache): New function.
(ia64_get_cached_proc_info): Adjust for get_script_cache() and
	put_script_cache() changes.
(ia64_find_save_locs): Ditto.
(ia64_script_cache_init): Call flush_script_cache() instead of
	opening-coding the equivalent code.

a157d632f7 (desc_is_active): Need to cast 1 to (unw_word_t) before shifting it by
a value that is potentially > 31.  Casting it to (unsigned long)
	is not enough on 32-bit platforms.
(create_state_record_for): Cast 0xf to (unw_word_t) instead of
	(unsigned long) to avoid losing bits on 32-bit platforms.

fe2dfccdf9 Include <alloca.h>.
(access_reg) [HAVE_SYS_UC_ACCESS_H]: Sanitize and simplify this routine.  Turns out
	uc_access(3) works pretty much the way we need it, the only problem is that
	the unwind info for getcontext() seems to be missing as of HP-UX 11.22.
(ia64_uc_access_reg): New function.
