26232 (shared_var_p): New inline function.
26233 (unshare_variable): Maintain cur_loc_changed and

26235 replace it there with new_var. Just copy cur_loc instead of

26256 already, reset in_changed_variables flag for it and propagate
26257 cur_loc_changed over to the new variable. On empty var
26258 always set cur_loc_changed. Set in_changed_variables on whatever
26259 var is added to changed_variables.
26260 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
26261 Use shared_var_p. When removing loc that is equal to cur_loc,
26262 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
26263 end, don't set it to something else, just call variable_was_changed.
26264 (delete_slot_part): Use shared_var_p. When cur_loc equals to

26268 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
26269 allocated. Always create SUBREGs if simplify_subreg failed.
26270 Prefer to use cur_loc, when that fails and still in

26272 cur_loc_changed of variables which had to change cur_loc and
26273 compute elcd->cur_loc_changed if any of the subexpressions used
26274 had to change cur_loc.
26275 (vt_expand_loc): Adjust to pass arguments in
26276 expand_loc_callback_data structure.

26280 that weren't used for any other decl in current
26281 emit_notes_for_changes call call vt_expand_loc_dummy to update
26282 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
26283 first loc_chain location if NULL before. Always use just
26284 cur_loc instead of first loc_chain location. When cur_loc_changed
26285 is false, when not --enable-checking=rtl just don't emit any note.
26286 When rtl checking, compute the note and assert it is the same
26287 as previous note. Clear cur_loc_changed and in_changed_variables
26288 at the end before removing from changed_variables.
