7919 cur_loc_changed and in_changed_variables fields.
7920 (variable_canonicalize): Remove.
7921 (shared_var_p): New inline function.
7922 (unshare_variable): Maintain cur_loc_changed and
7923 in_changed_variables fields. If var was in changed_variables,
7924 replace it there with new_var. Just copy cur_loc instead of
7925 resetting it to something else.
7926 (variable_union): Don't recompute cur_loc. Use shared_var_p.
7927 (dataflow_set_union): Don't call variable_canonicalize.
7928 (loc_cmp): If both x and y are DEBUG_EXPRs, compare uids
7929 of their DEBUG_EXPR_TREE_DECLs.
7930 (canonicalize_loc_order_check): Verify that cur_loc is NULL
7931 and in_changed_variables and cur_loc_changed is false.
7932 (variable_merge_over_cur): Clear cur_loc, in_changed_variables

7934 (variable_merge_over_src): Don't call variable_canonicalize.
7935 (dataflow_set_preserve_mem_locs): Use shared_var_p. When
7936 removing loc that is equal to cur_loc, clear cur_loc,
7937 set cur_loc_changed and ensure variable_was_changed is called.
7938 (dataflow_set_remove_mem_locs): Use shared_var_p. Only
7939 compare pointers in cur_loc check, if it is equal to loc,
7940 clear cur_loc and set cur_loc_changed. Don't recompute cur_loc here.

7942 don't compare cur_loc.
7943 (dataflow_set_different_1): Adjust variable_different_p caller.
7944 (variable_was_changed): If dv had some var in changed_variables
7945 already, reset in_changed_variables flag for it and propagate
7946 cur_loc_changed over to the new variable. On empty var
7947 always set cur_loc_changed. Set in_changed_variables on whatever
7948 var is added to changed_variables.
7949 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
7950 Use shared_var_p. When removing loc that is equal to cur_loc,
7951 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
7952 end, don't set it to something else, just call variable_was_changed.
7953 (delete_slot_part): Use shared_var_p. When cur_loc equals to
7954 loc being removed, clear cur_loc and set cur_loc_changed.
7955 Set cur_loc_changed if all locations have been removed.
7956 (struct expand_loc_callback_data): New type.
7957 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
7958 allocated. Always create SUBREGs if simplify_subreg failed.
7959 Prefer to use cur_loc, when that fails and still in
7960 changed_variables (and seen first time) recompute it. Set
7961 cur_loc_changed of variables which had to change cur_loc and
7962 compute elcd->cur_loc_changed if any of the subexpressions used
7963 had to change cur_loc.
7964 (vt_expand_loc): Adjust to pass arguments in
7965 expand_loc_callback_data structure.
7966 (vt_expand_loc_dummy): New function.
7967 (emitted_notes): New variable.
7968 (emit_note_insn_var_location): For VALUEs and DEBUG_EXPR_DECLs
7969 that weren't used for any other decl in current
7970 emit_notes_for_changes call call vt_expand_loc_dummy to update
7971 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
7972 first loc_chain location if NULL before. Always use just
7973 cur_loc instead of first loc_chain location. When cur_loc_changed
7974 is false, when not --enable-checking=rtl just don't emit any note.
7975 When rtl checking, compute the note and assert it is the same
7976 as previous note. Clear cur_loc_changed and in_changed_variables
7977 at the end before removing from changed_variables.
7978 (check_changed_vars_3): New function.
7979 (emit_notes_for_changes): Traverse changed_vars to call
7980 check_changed_vars_3 on each changed var.
7981 (emit_notes_for_differences_1): Clear cur_loc_changed and

7983 (emit_notes_for_differences_2): Clear cur_loc if new variable appears.
