On my CentOS 5 box, in a C++ program that does much arithmetic, including numerous matrix multiplications, I have a situation in in which the result depends on the nature of nearby I/O. Thus, with all arithmetic done with type double, and where values are mostly in the range [-1.0e0,+1.0e0] or nearby, I do: cerr << "some stuff" << endl; mat3 = matmult(mat1,mat2); I

Well, that didn't take long. :-) I have found two new surprises in DSCallGraph as built by TDDataStructures. Consider the following program, which is complete and self-contained and which has one simple indirect call site: volatile int unknown; static void red() { } static void

Hi, I have to install a small network in a school in a nearby village. The network will be Linux-only, one server and fifteen desktops. Here's the idea. 1) Authentication should be managed centrally on the server. 2) User home directories should also be on the server. 3) Users should all have disk quotas, something like 1 GB per user. 4) Some shared directories should be read/write for

Dear Ben, Just a few comments on DSA: 1) I'll try out your example C++ code below and see if I can get the same results that you do. However, I'm at a conference right now (Usenix Security), so I don't know exactly when I'll get to it. 2) DSA can get pessimistic results when dealing with external code (as Andrew described). It is designed for whole program analysis, meaning

OK, I have switched to TDDataStructures as well, and I am also seeing much better (for my purposes) results in simple tests. I'll keep poking at this some more and

If you aren't going to be in the San Francisco bay-area a week from now, you can stop reading this message. It's time for another LLVM bay-area social gathering, which will be held one week today on Wednesday, September 7th, starting 7pm at St. Stephen's Green in Mountain View. They still have good food, lots of beer and are a short walk away from the Mountain View Caltrain and VTA

Actually, it seems our own Eli has written rather a good description of these code models: http://eli.thegreenplace.net/2012/01/03/understanding-the-x64-code-models/. Well worth the read (the default models he talks about at the

Hi, quite often I find myself using commands like $ ssh foo nc bar 12345 to connect to another host behind a firewall, and I also have a lot of these commands in my ssh config file. Since this relies on the server having netcat available (which a lot don't, or in some really old version that will not shut down properly) it breaks often, and I wonder whether it would make sense to have an

Suppose...: - For non-releases: "git" + We take the first 6 chars of git commit - For releases: "ver" + major + "." + minor - For tar-balls: Something clever, maybe involving the date ...that we embed such a version in Syslinux core and in all OS programs and modules. Maybe even with some nearby magic so that a "whichver" command can examine and answer.

Tracking down this bug was joint work with Jermoe Asselin (jerome at hivnet.ubc.ca) and Patrick Connolly (p.connolly at hortresearch.co.nz). We collectively were able to determine that this is a problem in Windows 2000 but not in Linux. Timezones of the form GMT-5, GMT+3, etc. do not work properly in Windows 2000 for nearby dates in daylight savings time although they do work for nearby dates

I've got a single IAXy installed in a little office nearby and got a call from someone on site a finew mintues ago. Apparently they couldn't make a call on that extension. They'd pick up the phone and get nothing; no dial-tone. Running "iax2 show peers" showed the unit still registered and I could ping it too. Didn't try to call it while it was doing this; sorry. The

In an earlier message (http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-August/042298.html), Andrew Lenharth suggested that EQTDDataStructures (from the poolalloc project) may only try to resolve indirect function calls. However, I am now finding that the generated DSCallGraph over-approximates the callees in a very simple indirect call. Some over-approximation is unavoidable, but this case

I am learning Rails 3 and need some help on Ajax part. I am trying to accomplish the following: There is a textarea on the page which has a length of letters constraint, say 100. Every time a symbol is typed there,a nearby label tells you how many letters you have left. I plan to use Ajax to do this. I googled for a few hours and could not figure out how to do this. So far what I have done is
