2006 cur_loc_changed and in_changed_variables fields.
2007 (variable_canonicalize): Remove.
2008 (shared_var_p): New inline function.
2009 (unshare_variable): Maintain cur_loc_changed and
2010 in_changed_variables fields. If var was in changed_variables,
2011 replace it there with new_var. Just copy cur_loc instead of
2012 resetting it to something else.
2013 (variable_union): Don't recompute cur_loc. Use shared_var_p.

2015 (loc_cmp): If both x and y are DEBUG_EXPRs, compare uids
2016 of their DEBUG_EXPR_TREE_DECLs.
2017 (canonicalize_loc_order_check): Verify that cur_loc is NULL
2018 and in_changed_variables and cur_loc_changed is false.
2019 (variable_merge_over_cur): Clear cur_loc, in_changed_variables
2020 and cur_loc_changed. Don't update cur_loc here.
2021 (variable_merge_over_src): Don't call variable_canonicalize.
2022 (dataflow_set_preserve_mem_locs): Use shared_var_p. When
2023 removing loc that is equal to cur_loc, clear cur_loc,
2024 set cur_loc_changed and ensure variable_was_changed is called.
2025 (dataflow_set_remove_mem_locs): Use shared_var_p. Only

2027 clear cur_loc and set cur_loc_changed. Don't recompute cur_loc here.

2031 (variable_was_changed): If dv had some var in changed_variables
2032 already, reset in_changed_variables flag for it and propagate
2033 cur_loc_changed over to the new variable. On empty var
2034 always set cur_loc_changed. Set in_changed_variables on whatever
2035 var is added to changed_variables.
2036 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
2037 Use shared_var_p. When removing loc that is equal to cur_loc,
2038 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
2039 end, don't set it to something else, just call variable_was_changed.
2040 (delete_slot_part): Use shared_var_p. When cur_loc equals to
2041 loc being removed, clear cur_loc and set cur_loc_changed.
2042 Set cur_loc_changed if all locations have been removed.
2043 (struct expand_loc_callback_data): New type.
2044 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
2045 allocated. Always create SUBREGs if simplify_subreg failed.
2046 Prefer to use cur_loc, when that fails and still in
2047 changed_variables (and seen first time) recompute it. Set
2048 cur_loc_changed of variables which had to change cur_loc and
2049 compute elcd->cur_loc_changed if any of the subexpressions used
2050 had to change cur_loc.
2051 (vt_expand_loc): Adjust to pass arguments in
2052 expand_loc_callback_data structure.
2053 (vt_expand_loc_dummy): New function.
2054 (emitted_notes): New variable.
2055 (emit_note_insn_var_location): For VALUEs and DEBUG_EXPR_DECLs
2056 that weren't used for any other decl in current
2057 emit_notes_for_changes call call vt_expand_loc_dummy to update
2058 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
2059 first loc_chain location if NULL before. Always use just
2060 cur_loc instead of first loc_chain location. When cur_loc_changed
2061 is false, when not --enable-checking=rtl just don't emit any note.
2062 When rtl checking, compute the note and assert it is the same
2063 as previous note. Clear cur_loc_changed and in_changed_variables
2064 at the end before removing from changed_variables.
2065 (check_changed_vars_3): New function.
2066 (emit_notes_for_changes): Traverse changed_vars to call
2067 check_changed_vars_3 on each changed var.
2068 (emit_notes_for_differences_1): Clear cur_loc_changed and

2070 (emit_notes_for_differences_2): Clear cur_loc if new variable appears.
2071 (vt_emit_notes): Initialize and destroy emitted_notes.
