--- NEW FILE gcc44-rh503816-1.patch ---
2009-06-21 Jakub Jelinek <jakub at redhat.com>
* var-tracking.c (struct shared_hash_def, shared_hash): New types.
(dataflow_set): Change vars type from htab_t to shared_hash.
(shared_hash_pool, empty_shared_hash): New variables.
(vars_clear): Removed.
(shared_hash_shared, shared_hash_htab, shared_hash_copy,
shared_hash_find_slot_unshare, shared_hash_find_slot,
shared_hash_find_slot_noinsert, shared_hash_find): New
static inlines.
(shared_hash_unshare, shared_hash_destroy): New functions.
(unshare_variable): Unshare set->vars if shared, use
shared_hash_htab.
(vars_copy): Use htab_traverse_noresize instead of htab_traverse.
(get_init_value, find_src_set_src, dump_dataflow_set,
clobber_variable_part, emit_notes_for_differences): Use
shared_hash_htab.
(dataflow_set_init): Remove second argument, set vars to
empty_shared_hash instead of creating a new htab.
(dataflow_set_clear): Call shared_hash_destroy and set vars
to empty_shared_hash instead of calling vars_clear.
(dataflow_set_copy): Don't call vars_copy, instead just share
the src htab with dst.
(variable_union): Use shared_hash_*, use initially NO_INSERT
lookup if set->vars is shared. Don't keep slot cleared before
calling unshare_variable. Unshare set->vars if needed.
Even ->refcount == 1 vars must be unshared if set->vars is shared
and var needs to be modified.
(variable_canonicalize): New function.
(dataflow_set_union): If dst->vars is empty, just share src->vars
with dst->vars and traverse with variable_canonicalize to canonicalize
and unshare what is needed.
(dataflow_set_different): If old_set and new_set use the same shared
htab, they aren't different. If number of htab elements is different,
htabs are different. Use shared_hash_*.
(dataflow_set_destroy): Call shared_hash_destroy instead of
htab_delete.
(compute_bb_dataflow, emit_notes_in_bb, vt_emit_notes): Don't pass
second argument to dataflow_set_init.
(vt_initialize): Likewise. Initialize shared_hash_pool and
empty_shared_hash, move bb in/out initialization afterwards.
Use variable_htab_free instead of NULL as changed_variables del hook.
(variable_was_changed): Change type of second argument to pointer to
dataflow_set. When inserting var into changed_variables, bump
refcount. Unshare set->vars if set is shared htab and slot needs to
be cleared.
(set_variable_part): Use shared_hash_*, use initially NO_INSERT
lookup if set->vars is shared. Unshare set->vars if needed.
Even ->refcount == 1 vars must be unshared if set->vars is shared
and var needs to be modified. Adjust variable_was_changed caller.
(delete_variable_part): Use shared_hash_*. Even ->refcount == 1
vars must be unshared if set->vars is shared and var needs to be
modified. Adjust variable_was_changed caller.
(emit_note_insn_var_location): Don't pool_free var.
(emit_notes_for_differences_1): Initialize empty_var->refcount to 0
instead of 1.
(vt_finalize): Call htab_delete on empty_shared_hash->htab and
free_alloc_pool on shared_hash_pool.
* hashtab.c (htab_traverse): Don't call htab_expand for
nearly empty hashtabs with sizes 7, 13 or 31.

--- NEW FILE gcc44-rh503816-2.patch ---
2009-06-23 Jakub Jelinek <jakub at redhat.com>
* var-tracking.c (unshare_variable): Force initialized to
be VAR_INIT_STATUS_INITIALIZED unless flag_var_tracking_uninit.
(set_variable_part): Likewise.
(struct variable_union_info): Remove pos_src field.
(vui_vec, vui_allocated): New variables.
(variable_union): Pass VAR_INIT_STATUS_UNKNOWN to unshare_variable
unconditionally. Avoid XCVECNEW/free for every sorting, for dst_l
== 1 use a simpler sorting algorithm. Compute pos field right
away, don't fill in pos_src. For dst_l == 2 avoid qsort.
Avoid quadratic comparison if !flag_var_tracking_uninit.
(variable_canonicalize): Pass VAR_INIT_STATUS_UNKNOWN to
unshare_variable unconditionally.
(dataflow_set_different_2): Removed.
(dataflow_set_different): Don't traverse second hash table.
(compute_bb_dataflow): Pass VAR_INIT_STATUS_UNINITIALIZED
unconditionally to var_reg_set or var_mem_set.
(emit_notes_in_bb): Likewise.
(delete_variable_part): Pass VAR_INIT_STATUS_UNKNOWN to
unshare_variable.
(emit_note_insn_var_location): Don't set initialized to
VAR_INIT_STATUS_INITIALIZED early.
(vt_finalize): Free vui_vec if needed, clear vui_vec and
vui_allocated.
