var-tracking.c (unshare_variable): Force initialized to be VAR_INIT_STATUS_INITIALIZED unless flag_var_tracking_uninit.
* 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.
* rtl.c (rtx_equal_p): Don't implement on top of rtx_equal_p_cb.
