33804 already, reset in_changed_variables flag for it and propagate
33805 cur_loc_changed over to the new variable. On empty var
33806 always set cur_loc_changed. Set in_changed_variables on whatever
33807 var is added to changed_variables.
33808 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
33809 Use shared_var_p. When removing loc that is equal to cur_loc,
33810 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
33811 end, don't set it to something else, just call variable_was_changed.
33812 (delete_slot_part): Use shared_var_p. When cur_loc equals to

33814 Set cur_loc_changed if all locations have been removed.
33815 (struct expand_loc_callback_data): New type.
33816 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
33817 allocated. Always create SUBREGs if simplify_subreg failed.
33818 Prefer to use cur_loc, when that fails and still in
33819 changed_variables (and seen first time) recompute it. Set
33820 cur_loc_changed of variables which had to change cur_loc and
33821 compute elcd->cur_loc_changed if any of the subexpressions used
33822 had to change cur_loc.
33823 (vt_expand_loc): Adjust to pass arguments in
33824 expand_loc_callback_data structure.

33828 that weren't used for any other decl in current

33830 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
33831 first loc_chain location if NULL before. Always use just
33832 cur_loc instead of first loc_chain location. When cur_loc_changed
33833 is false, when not --enable-checking=rtl just don't emit any note.
33834 When rtl checking, compute the note and assert it is the same
33835 as previous note. Clear cur_loc_changed and in_changed_variables
33836 at the end before removing from changed_variables.
33837 (check_changed_vars_3): New function.
