3804 * cselib.h (cselib_dummy_expand_value_rtx_cb): New prototype.
3805 * var-tracking.c: Include pointer-set.h.
3806 (variable): Change n_var_parts to char from int. Add
3807 cur_loc_changed and in_changed_variables fields.
3808 (variable_canonicalize): Remove.
3809 (shared_var_p): New inline function.
3810 (unshare_variable): Maintain cur_loc_changed and
3811 in_changed_variables fields. If var was in changed_variables,
3812 replace it there with new_var. Just copy cur_loc instead of
3813 resetting it to something else.
3814 (variable_union): Don't recompute cur_loc. Use shared_var_p.
3815 (dataflow_set_union): Don't call variable_canonicalize.
3816 (loc_cmp): If both x and y are DEBUG_EXPRs, compare uids
3817 of their DEBUG_EXPR_TREE_DECLs.
3818 (canonicalize_loc_order_check): Verify that cur_loc is NULL
3819 and in_changed_variables and cur_loc_changed is false.
3820 (variable_merge_over_cur): Clear cur_loc, in_changed_variables
3821 and cur_loc_changed. Don't update cur_loc here.
3822 (variable_merge_over_src): Don't call variable_canonicalize.
3823 (dataflow_set_preserve_mem_locs): Use shared_var_p. When
3824 removing loc that is equal to cur_loc, clear cur_loc,
3825 set cur_loc_changed and ensure variable_was_changed is called.
3826 (dataflow_set_remove_mem_locs): Use shared_var_p. Only
3827 compare pointers in cur_loc check, if it is equal to loc,
3828 clear cur_loc and set cur_loc_changed. Don't recompute cur_loc here.
3829 (variable_different_p): Remove compare_current_location argument,
3830 don't compare cur_loc.
3831 (dataflow_set_different_1): Adjust variable_different_p caller.
3832 (variable_was_changed): If dv had some var in changed_variables
3833 already, reset in_changed_variables flag for it and propagate
3834 cur_loc_changed over to the new variable. On empty var
3835 always set cur_loc_changed. Set in_changed_variables on whatever
3836 var is added to changed_variables.
3837 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
3838 Use shared_var_p. When removing loc that is equal to cur_loc,
3839 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
3840 end, don't set it to something else, just call variable_was_changed.
3841 (delete_slot_part): Use shared_var_p. When cur_loc equals to
3842 loc being removed, clear cur_loc and set cur_loc_changed.
3843 Set cur_loc_changed if all locations have been removed.
3844 (struct expand_loc_callback_data): New type.
3845 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
3846 allocated. Always create SUBREGs if simplify_subreg failed.
3847 Prefer to use cur_loc, when that fails and still in
3848 changed_variables (and seen first time) recompute it. Set
3849 cur_loc_changed of variables which had to change cur_loc and
3850 compute elcd->cur_loc_changed if any of the subexpressions used
3851 had to change cur_loc.
3852 (vt_expand_loc): Adjust to pass arguments in
3853 expand_loc_callback_data structure.
3854 (vt_expand_loc_dummy): New function.
3855 (emitted_notes): New variable.
3856 (emit_note_insn_var_location): For VALUEs and DEBUG_EXPR_DECLs
3857 that weren't used for any other decl in current
3858 emit_notes_for_changes call call vt_expand_loc_dummy to update
3859 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
3860 first loc_chain location if NULL before. Always use just
3861 cur_loc instead of first loc_chain location. When cur_loc_changed
3862 is false, when not --enable-checking=rtl just don't emit any note.
3863 When rtl checking, compute the note and assert it is the same
3864 as previous note. Clear cur_loc_changed and in_changed_variables
3865 at the end before removing from changed_variables.
3866 (check_changed_vars_3): New function.
3867 (emit_notes_for_changes): Traverse changed_vars to call
3868 check_changed_vars_3 on each changed var.
3869 (emit_notes_for_differences_1): Clear cur_loc_changed and
3870 in_changed_variables. Recompute cur_loc of new_var.
3871 (emit_notes_for_differences_2): Clear cur_loc if new variable appears.
3872 (vt_emit_notes): Initialize and destroy emitted_notes.
