How to generate an updated graph of the order of passes?

[compor]

Is there a way to generate up to date (or with whatever recent GCC tree) table of passes like in this documentation page? Are those scripts available anywhere? How much manual tweaking is involved?

I generated it using generate-passes-svg.py via make docs/passes.svg, but I haven't tried regenerating it in a while.

@davidmalcolm thanks, I'll give it a go with a more recent GCC.
