2040 already, reset in_changed_variables flag for it and propagate
2041 cur_loc_changed over to the new variable. On empty var
2042 always set cur_loc_changed. Set in_changed_variables on whatever
2043 var is added to changed_variables.
2044 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
2045 Use shared_var_p. When removing loc that is equal to cur_loc,
2046 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
2047 end, don't set it to something else, just call variable_was_changed.
2048 (delete_slot_part): Use shared_var_p. When cur_loc equals to

2052 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
2053 allocated. Always create SUBREGs if simplify_subreg failed.
2054 Prefer to use cur_loc, when that fails and still in
2055 changed_variables (and seen first time) recompute it. Set
2056 cur_loc_changed of variables which had to change cur_loc and
2057 compute elcd->cur_loc_changed if any of the subexpressions used
2058 had to change cur_loc.
2059 (vt_expand_loc): Adjust to pass arguments in
2060 expand_loc_callback_data structure.
2061 (vt_expand_loc_dummy): New function.

2066 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
2067 first loc_chain location if NULL before. Always use just
2068 cur_loc instead of first loc_chain location. When cur_loc_changed
2069 is false, when not --enable-checking=rtl just don't emit any note.
2070 When rtl checking, compute the note and assert it is the same
2071 as previous note. Clear cur_loc_changed and in_changed_variables
2072 at the end before removing from changed_variables.
2073 (check_changed_vars_3): New function.
