I have been able to build similar tool for at least two radically

important proprietary compiler but from feedback people we talked
with, we should not worry. Yes, that is not an ISO-approved thing,
but just a data point something `vaguely equivalent to this in the
general g++' context has been done. We have not released IPR yet, but
it be open source a fairly open license.
It would be great if this could be the basis for an ASIS-similar
standard for C++, even if it is only a de factor semi-standard :-)

IPR doesn't attempt to replace compiler internal data structures for
writing optimizations. Nor it is a plugin into GIMPLE or RTL -- as I
said, it is designed to be compiler neutral.
