[Lightning] Controlling the generated code size

[Ludovic Courtès]

Hi,

Is there a way, while generating code, to make sure that it won't
produce more code than a certain amount?  This is typically useful to
prevent buffer overflows in code-generating functions that look like:


  void
  generate_code (char *input_buffer, size_t input_buffer_size)
  {
  ...
  }

Of course, one can check the difference between the current IP and
INPUT_BUFFER every three instruction or so and make sure it is always
lower than INPUT_BUFFER_SIZE, but this isn't very reliable.

Thanks,
Ludovic.
