Excellent idea. :)

Given this, I'm thinking we lobby Joe Darcy to use a copy of hotspot 14 stable as the hotspot to use with OpenJDK6. Which can then evolve with community input. Andrew can do the first commit. I agree. The hsx team can easily keep the gcc version they use stable, so they don't need to introduce changes to make hsx code work with latest gcc releases. OpenJDK 6, otoh, is used in distributions that ship bleeding edge gccs, so it needs to keep evolving along with gcc, which implies two different drivers, and that's a good reason to copy and go.

I wouldn't call 4.3 'bleeding edge'. it's over a year since it was released. Heck, even Debian has it (though I guess it's not in RHEL).

No one has yet adequately explained why we now have a 'read only' HotSpot repository. This isn't about the HotSpot team wanting to keep using an old version of gcc - this patch is a backported from the HotSpot tree.

In order to avoid accumulating gcc patchlets monotonously in OpenJDK 6 clone of hsx, such fixes should also be submitted to the hotspot team, where they apply to the in development version of hotspot.

Well, yes. Indeed I'd expect them to be applied to the HotSpot tree first and then backported to the stable OpenJDK6 tree as appropriate.

Speaking of which, can we have an HotSpot tree we can actually commit to sometime soon?
