22891 already, reset in_changed_variables flag for it and propagate
22892 cur_loc_changed over to the new variable. On empty var
22893 always set cur_loc_changed. Set in_changed_variables on whatever
22894 var is added to changed_variables.
22895 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
22896 Use shared_var_p. When removing loc that is equal to cur_loc,
22897 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
22898 end, don't set it to something else, just call variable_was_changed.
22899 (delete_slot_part): Use shared_var_p. When cur_loc equals to

22901 Set cur_loc_changed if all locations have been removed.
22902 (struct expand_loc_callback_data): New type.
22903 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
22904 allocated. Always create SUBREGs if simplify_subreg failed.
22905 Prefer to use cur_loc, when that fails and still in
22906 changed_variables (and seen first time) recompute it. Set
22907 cur_loc_changed of variables which had to change cur_loc and
22908 compute elcd->cur_loc_changed if any of the subexpressions used
22909 had to change cur_loc.
22910 (vt_expand_loc): Adjust to pass arguments in
22911 expand_loc_callback_data structure.

22915 that weren't used for any other decl in current

22917 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
22918 first loc_chain location if NULL before. Always use just
22919 cur_loc instead of first loc_chain location. When cur_loc_changed
22920 is false, when not --enable-checking=rtl just don't emit any note.
22921 When rtl checking, compute the note and assert it is the same
22922 as previous note. Clear cur_loc_changed and in_changed_variables
22923 at the end before removing from changed_variables.
22924 (check_changed_vars_3): New function.
