Tool to visualize C2 Ideal IR

[Volker Simonis]

Hi Marcelino,

IdealGraphVisualizer is now part of the hotspot repository. See:

hotspot/src/share/tools/IdealGraphVisualizer

You should be able to easily build it yourself. If you encounter any
problems, post them on hotspot-dev (CC'ed).

Regards,
Volker

( http://dl.acm.org/citation.cfm?id=1788391 ) and seems amazing. But I can't find the tool for download anywhere.
