36313 already, reset in_changed_variables flag for it and propagate
36314 cur_loc_changed over to the new variable. On empty var
36315 always set cur_loc_changed. Set in_changed_variables on whatever
36316 var is added to changed_variables.
36317 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
36318 Use shared_var_p. When removing loc that is equal to cur_loc,
36319 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
36320 end, don't set it to something else, just call variable_was_changed.
36321 (delete_slot_part): Use shared_var_p. When cur_loc equals to

36325 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
36326 allocated. Always create SUBREGs if simplify_subreg failed.
36327 Prefer to use cur_loc, when that fails and still in

36329 cur_loc_changed of variables which had to change cur_loc and
36330 compute elcd->cur_loc_changed if any of the subexpressions used
36331 had to change cur_loc.
36332 (vt_expand_loc): Adjust to pass arguments in

36340 first loc_chain location if NULL before. Always use just
36341 cur_loc instead of first loc_chain location. When cur_loc_changed
36342 is false, when not --enable-checking=rtl just don't emit any note.
36343 When rtl checking, compute the note and assert it is the same
36344 as previous note. Clear cur_loc_changed and in_changed_variables
36345 at the end before removing from changed_variables.
