-ftree-vectorize just came up on the gentoo-dev list. I've not even
checked the URLs yet, but since it came up here, I thought I'd ask about
it and having gotten a response, here's the gist. (FWIW, I've been
running it experimentally for a bit now. No issues with it have I seen,
but I've not done a full emerge --emptytree system/world yet.) I'll
probably have a bit more to say about it after checking the tinyurls,
which at this point I don't even know where they go yet, let alone their

They've fixed quite a few of the ICE's since last I looked, though there's

I'd say that there's more ICE's on i686-pc-linux-gnu than
x86_64-*-linux-gnu, but there's still enough. Luckily Halcy0n was really
good for reducing testcases and pushing them upstream, so a lot of these
issues got fixed at the source.
