...ng. > > I'll be talking about this in a lightning talk, perhaps others have thoughts on this. Hi Joe, As you mentioned in your talk, I'm sympathetic to your desires, but highly skeptical of this approach - for a number of reasons. Off the top of my head: 1. This will (over time) accrete a ton of old gunk in the bitcode writer, and also slow down progress. 2. The use case for it is also very narrow (in contrast to having the *reader* handle old files, which many scenarios benefit from). 3. The open source project as a whole benefits from "forcing" users of LLVM to "s...

David, this is probably the wrong approach, based on the accreted awfulness of the X86 shuffle lowering code, which Eli and I have hacked on to improve somewhat. The correct approach is probably a rewrite based around what AltiVec does: Canonicalize to byte ops, and write all the patterns once rather than having to look for 6 different variants of the same patt...

...t really a "whole problem" to consider. Even if there is, I agree that the shortest path to solving my immediate problem is to do exactly as you suggest. I guess my take is that when faced with an architectural question that you eventually may have to address in full, quick fixes tend to accrete that have to be undone when you get around to the general solution, and these make implementing the general thing harder -- unless you have thought it out in advance and the quick fixes are in line with the eventual solution. Now it may turn out that there isn't any "general thing" h...

I am trying to simulate the trajectory of the pension assets of one person. In C-like syntax, it looks like this: daily.wage.growth = 1.001 # deterministic contribution.rate = 0.08 # deterministic 8% Wage = 10 # initial Asset = 0 # initial for (10,000 days) { Asset += contribution.rate * Wage

I'm working on debugging AVX shuffles and I ran into an interesting problem. The current isSHUFPMask predicate in X86ISelLowering needs to be generalized to operate on 128-bit or 256-bit masks. There are probably lots of other things to change too (LowerVECTOR_SHUFFLE_4wide, etc.) but I'll worry about that later. The generalized rule is: 1. For the low 64 bits of the result vector, the

Just got a pointer to this via ACM "TechNews Alert" for today: http://www.acm.org/technews/articles/2004-6/0818w.html#item2 Seems that "... French computer scientist Antoine Joux reported on Aug. 12 his discovery of a flaw in the MD5 algorithm, which is often used with digital signatures...." There's more in the article cited above.

If you?ve truly got the best solution, you?ll start to move things in the direction you want them to go. It?s not going to happen immediately, but in a do-ocracy, those who do things accrete ruling powers. Or, you can go fork EL6 or whatever other ?classic? distro that makes you happier.

These two patches implement the first (and hardest) part of the fix for CVE-2010-3851. This adds a way to specify the format when adding a drive, avoiding qemu's auto-detection. In order to avoid an explosion of different add_drive_* functions (we have 4 already), we have implemented a way to specify optional arguments to functions, so all we need is a single new 'add_drive_opts'

Linux Plays a Role in 'Titanic,' Photos By NASA, but Can It Take On Microsoft? By SEAN DAVIS Dow Jones Newswires [From The Wall Street Journal, April 3, 1998, page B7B] NEW YORK-The makers of "Titanic" used it to render the hit film's special effects. NASA uses it to stitch together pictures of Earth. It is free to anyone who wants it, but at least two companies are
