6149 (unshare_variable): Maintain cur_loc_changed and

6151 replace it there with new_var. Just copy cur_loc instead of

6158 and in_changed_variables and cur_loc_changed is false.
6159 (variable_merge_over_cur): Clear cur_loc, in_changed_variables

6162 (dataflow_set_preserve_mem_locs): Use shared_var_p. When
6163 removing loc that is equal to cur_loc, clear cur_loc,

6165 (dataflow_set_remove_mem_locs): Use shared_var_p. Only

6171 (variable_was_changed): If dv had some var in changed_variables
6172 already, reset in_changed_variables flag for it and propagate
6173 cur_loc_changed over to the new variable. On empty var
6174 always set cur_loc_changed. Set in_changed_variables on whatever
6175 var is added to changed_variables.
6176 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
6177 Use shared_var_p. When removing loc that is equal to cur_loc,
6178 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
6179 end, don't set it to something else, just call variable_was_changed.
6180 (delete_slot_part): Use shared_var_p. When cur_loc equals to

6184 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
6185 allocated. Always create SUBREGs if simplify_subreg failed.
6186 Prefer to use cur_loc, when that fails and still in

6188 cur_loc_changed of variables which had to change cur_loc and
6189 compute elcd->cur_loc_changed if any of the subexpressions used
6190 had to change cur_loc.
6191 (vt_expand_loc): Adjust to pass arguments in

6197 emit_notes_for_changes call call vt_expand_loc_dummy to update
6198 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
6199 first loc_chain location if NULL before. Always use just
6200 cur_loc instead of first loc_chain location. When cur_loc_changed
6201 is false, when not --enable-checking=rtl just don't emit any note.
6202 When rtl checking, compute the note and assert it is the same
6203 as previous note. Clear cur_loc_changed and in_changed_variables
6204 at the end before removing from changed_variables.
6205 (check_changed_vars_3): New function.
