Optimized methods cannot be overridden after Module#prepend

Description

It seems that optimized methods cannot overridden after Module#prepend.

module M
  def /(other)
    quo(other)
  end
end
class Fixnum
  prepend M
end
module M
  def %(other)
    0
  end

  def foo
    puts "m#foo"
  end
end
p 1 / 2 #=> (1/2)  overridden
p 1 % 2 #=> 1      not overridden
1.foo   #=> m#foo  overridden

Is there any good way to disable optimization in this case?

Applied in changeset r53179.


  • vm_method.c (rb_method_entry_make, check_override_opt_method):
    should check whether a newly created method override a optimize
    method in case the method is defined in a prepended module of a
    built-in class.
