11355 (shared_var_p): New inline function.
11356 (unshare_variable): Maintain cur_loc_changed and
11357 in_changed_variables fields. If var was in changed_variables,
11358 replace it there with new_var. Just copy cur_loc instead of

11378 (variable_was_changed): If dv had some var in changed_variables
11379 already, reset in_changed_variables flag for it and propagate
11380 cur_loc_changed over to the new variable. On empty var
11381 always set cur_loc_changed. Set in_changed_variables on whatever
11382 var is added to changed_variables.
11383 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
11384 Use shared_var_p. When removing loc that is equal to cur_loc,
11385 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
11386 end, don't set it to something else, just call variable_was_changed.
11387 (delete_slot_part): Use shared_var_p. When cur_loc equals to
11388 loc being removed, clear cur_loc and set cur_loc_changed.
11389 Set cur_loc_changed if all locations have been removed.
11390 (struct expand_loc_callback_data): New type.
11391 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
11392 allocated. Always create SUBREGs if simplify_subreg failed.
11393 Prefer to use cur_loc, when that fails and still in
11394 changed_variables (and seen first time) recompute it. Set
11395 cur_loc_changed of variables which had to change cur_loc and
11396 compute elcd->cur_loc_changed if any of the subexpressions used
11397 had to change cur_loc.
11398 (vt_expand_loc): Adjust to pass arguments in
11399 expand_loc_callback_data structure.

11403 that weren't used for any other decl in current

11405 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
11406 first loc_chain location if NULL before. Always use just
11407 cur_loc instead of first loc_chain location. When cur_loc_changed
11408 is false, when not --enable-checking=rtl just don't emit any note.
11409 When rtl checking, compute the note and assert it is the same
11410 as previous note. Clear cur_loc_changed and in_changed_variables
11411 at the end before removing from changed_variables.
11412 (check_changed_vars_3): New function.
11413 (emit_notes_for_changes): Traverse changed_vars to call
11414 check_changed_vars_3 on each changed var.
