35420 (variable_canonicalize): Remove.
35421 (shared_var_p): New inline function.
35422 (unshare_variable): Maintain cur_loc_changed and

35424 replace it there with new_var. Just copy cur_loc instead of
35425 resetting it to something else.

35434 (variable_merge_over_src): Don't call variable_canonicalize.
35435 (dataflow_set_preserve_mem_locs): Use shared_var_p. When

35445 already, reset in_changed_variables flag for it and propagate
35446 cur_loc_changed over to the new variable. On empty var
35447 always set cur_loc_changed. Set in_changed_variables on whatever
35448 var is added to changed_variables.
35449 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
35450 Use shared_var_p. When removing loc that is equal to cur_loc,
35451 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
35452 end, don't set it to something else, just call variable_was_changed.
35453 (delete_slot_part): Use shared_var_p. When cur_loc equals to
35454 loc being removed, clear cur_loc and set cur_loc_changed.

35457 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
35458 allocated. Always create SUBREGs if simplify_subreg failed.
35459 Prefer to use cur_loc, when that fails and still in

35461 cur_loc_changed of variables which had to change cur_loc and
35462 compute elcd->cur_loc_changed if any of the subexpressions used
35463 had to change cur_loc.
35464 (vt_expand_loc): Adjust to pass arguments in
35465 expand_loc_callback_data structure.

35469 that weren't used for any other decl in current

35471 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
35472 first loc_chain location if NULL before. Always use just
35473 cur_loc instead of first loc_chain location. When cur_loc_changed
35474 is false, when not --enable-checking=rtl just don't emit any note.
35475 When rtl checking, compute the note and assert it is the same
35476 as previous note. Clear cur_loc_changed and in_changed_variables
35477 at the end before removing from changed_variables.
35478 (check_changed_vars_3): New function.
