-ftree-vectorize just came up on the gentoo-dev list. I've not even |
2 |
checked the URLs yet, but since it came up here, I thought I'd ask about |
3 |
it and having gotten a response, here's the gist. (FWIW, I've been |
4 |
running it experimentally for a bit now. No issues with it have I seen, |
5 |
but I've not done a full emerge --emptytree system/world yet.) I'll |
6 |
probably have a bit more to say about it after checking the tinyurls, |
7 |
which at this point I don't even know where they go yet, let alone their |
8 |
content. |

They've fixed quite a few of the ICE's since last I looked, though there's |
20 |
more than a couple that went in after 4.1.1. 4.2 is a little better, but |
21 |
I'm having enough trouble getting it to build things properly _without_ |
22 |
using any fancy flags right now. ;p |

I'd say that there's more ICE's on i686-pc-linux-gnu than |
29 |
x86_64-*-linux-gnu, but there's still enough. Luckily Halcy0n was really |
30 |
good for reducing testcases and pushing them upstream, so a lot of these |
31 |
issues got fixed at the source. |
