9263 replace it there with new_var. Just copy cur_loc instead of

9270 and in_changed_variables and cur_loc_changed is false.

9274 (dataflow_set_preserve_mem_locs): Use shared_var_p. When
9275 removing loc that is equal to cur_loc, clear cur_loc,
9276 set cur_loc_changed and ensure variable_was_changed is called.
9277 (dataflow_set_remove_mem_locs): Use shared_var_p. Only

9283 (variable_was_changed): If dv had some var in changed_variables
9284 already, reset in_changed_variables flag for it and propagate
9285 cur_loc_changed over to the new variable. On empty var
9286 always set cur_loc_changed. Set in_changed_variables on whatever
9287 var is added to changed_variables.
9288 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
9289 Use shared_var_p. When removing loc that is equal to cur_loc,
9290 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
9291 end, don't set it to something else, just call variable_was_changed.
9292 (delete_slot_part): Use shared_var_p. When cur_loc equals to
9293 loc being removed, clear cur_loc and set cur_loc_changed.

9296 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
9297 allocated. Always create SUBREGs if simplify_subreg failed.
9298 Prefer to use cur_loc, when that fails and still in

9300 cur_loc_changed of variables which had to change cur_loc and
9301 compute elcd->cur_loc_changed if any of the subexpressions used
9302 had to change cur_loc.
9303 (vt_expand_loc): Adjust to pass arguments in

9308 that weren't used for any other decl in current
9309 emit_notes_for_changes call call vt_expand_loc_dummy to update
9310 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
9311 first loc_chain location if NULL before. Always use just
9312 cur_loc instead of first loc_chain location. When cur_loc_changed
9313 is false, when not --enable-checking=rtl just don't emit any note.
9314 When rtl checking, compute the note and assert it is the same
9315 as previous note. Clear cur_loc_changed and in_changed_variables
9316 at the end before removing from changed_variables.
9317 (check_changed_vars_3): New function.
9318 (emit_notes_for_changes): Traverse changed_vars to call
