Another alternative thought of for the fix was to,

Make the Parameters to be the default def of the next use. In this case,
the condition mentioned above will not expand the variable.

if (!bitmap_bit_p (SA.partition_has_default_def, i))
  {
    expand_one_var (var, true, true);
    gcc_assert (SA.partition_to_pseudo[i]);
  }
