I have already asked to have that revert approved in another thread. InstCombine has no code owner which means Chris is the de facto owner.

And it would have been really nice to have a test for r222562 :-( Cheers, Rafael

But the second looks like it's an ABI change, which I thought were forbidden even at the C++ level for point releases. Cheers. Tim.

Is there a FreeBSD code owner? These patches seem to only affect FreeBSD and are fairly trivial. As long as Tim and Evan don't have any objections I think these can be merged. -Tom

This is just on the edge of what I'd consider eligible for a dot release, technically being a new feature, but it does fix assert-on-valid bugs, so there is also bug-fixing value in taking it. -Hal> > -Dimitry > >-- Hal Finkel Assistant Computational Scientist Leadership Computing Facility Argonne National Laboratory
