oldest supported isl version

[Sven Verdoolaege]

Hi,

with the release of isl 0.15 coming closer, I'd like to take
advantage of the fact that it is going to break compatibility
to remove some stuff that has been deprecated a long time ago.
I'll try and keep stuff that might still be needed by graphite,
but I'd need the answer to the following question.

What is the oldest version of isl that is supported by
any actively maintained version of gcc?

I'll assume that anything that was already deprecated in that
version can be removed.

Thanks,

skimo

Not really.

You may be using features that have already been deprecated
in 0.14 but that you still need to support older versions
of isl. If I start ripping those out, you won't be happy,
unless you are willing to give up on support for those
older versions. One such feature is isl_int. You'd have
to switch to isl_val (and drop support for versions of isl
that didn't have isl_val) before I could completely remove that.
