Hey Chuck, I'm afraid I can't reproduce your error but...a problem you may run into later is that opt will complain with opt: llvm/lib/VMCore/Pass.cpp:149: void<unnamed>::PassRegistrar::RegisterPass(const llvm::PassInfo&): Assertion `Inserted && "Pass registered multiple times!"' failed. Aborted I "fixed" this by replacing the LLVMLIBS line in

While learning to write LLVM passes and following the precise instructions under http://llvm.org/docs/WritingAnLLVMPass.html, <http://llvm.org/docs/WritingAnLLVMPass.html> I got this error when loading the hello pass to run the test program: opt -load ./Release/lib/Hello.so -hello < test/test.bc > /dev/null Error opening './Release/lib/Hello.so': ./Release/lib/Hello.so:

Dear editor: I'm writing this letter to enquire where can I download the package of "lmtest". Can you send me this package? THanks a lot. Best regards, Shu-Fei Wu

How to generate a new factor variable by two other factor variables? For example, if I have two factor variables, factorA and factorB, factorA factorB 0 0 0 0 1 0 0 1 1 1 Is there a simple way to generate a new 4-levels factor variable as factorC factorA factorB 0 0 0 0 0 0 1 1 0 2 0 1

Hi, When I used BRugs (Version 0.8.0), I found a bug about the findOpenBUGS way using "OpenBUGS_PATH". I don't know how to contact the developer, so I think someone here may help me. The issue is: I want to use OpenBUGS/BRugs in a portable way in windows, so I set the environment variable "OpenBUGS_PATH" to tell BRugs the path to OpenBugs. But the R library BRugs is still

Dear all, I have set up one unprivileged Domain-1 with help of FedoraQuickStart and some help from you. Now I want to install some other OS to Domain-2. How can I install a different OS (say Redhat 7.3) onto a unprivileged domain? Do I have to copy all files from an existed installation to an image file?

Thanks, Shu, I guess I haven't updated since my post went out. There are actually 2 problems: 1. mis-compilation: My LLVM-2.5 turned out to be mis-compiled using gcc-4.4.0 (surprise to me) on Debian4-32b. I tried a few different compilers, and gcc-4.0.4 (a relatively old one, again surprised me) seems to work out fine. Question: is there a good/quick/reliable way to figure out whether a

Dear R, I'm doing some simulation work and it takes me a lot of time to do it in R. So I try to implement it in C code, but I want to use some R functions directly for my lazy and the robustness of code. For example, I will use lm and nlm in my program. How could I use R's lm and nlm function directly? I thinks these functions are not included in the R's include directory. Do I need

Are any plans for an API that would allow ZFS commands including snapshot/rollback integrated with customer''s application? Thanks, Cherry

Dear R user, How could I use function in-visible to user in my code? For example 'survfitKM' or 'survfit.formula' in package survival. These functions are in-visible to user. Thanks, Shuguang

Hi, Does the current LLVM backend support reading in profile information (without preserving across transformations)? An earlier poster http://groups.google.com/group/llvm-dev/browse_thread/thread/4bd65dbe84394bb7 noted that accessing execution counts in a MachineFunction pass (using the BasicBlock* corresponding to the respective MachineBasicBlock) returned 0 for all blocks. Running llc with

Dear All, we've been having some intermittent problems with students who's home directories are on a Sun E450 running Samba 2.0.6. I'm not totally convinced that the problem is caused by the server, but may be the network. However, I've had a look at the log.smb file and I'm seeing some error messages that I've not come across before: [2001/02/23 18:20:40, 0]

Hi, My rsync is stopped working suddenly I got following in verbose and log, mkstemp failed: No such file or directory and rsync error: received SIGUSR1 or SIGINT (code 20) at rsync.c(229) my rsync code : rsync -az -e ssh --delete $HOSTTOBACKUP:$SOURCE $DR_BACKUP_DIR/daily.0 >$tempfile 2>&1 the same code was working last week, what will be the problem, how to proceed to fix?

Thanks for such a rapid response! > Don't know about Passes in the backend, but this could be a problem of > an FunctionPassManager trying to use a ModulePass. I manually applied the patch you provided for llc (I'm using the 2.5 release of LLVM not ToT) and it fixed my compilation error. When your patch replaced the FunctionPassManager used by llc with a PassManager the error went

Hi All, I would like to ask two questions about printCoefmat(). First, I found a behavior of printCoefmat() that looks strange to me, but I am not sure whether this is an intended behavior: ``` r set.seed(5689417) n <- 10000 x1 <- rnorm(n) x2 <- rnorm(n) y <- .5 * x1 + .6 * x2 + rnorm(n, -0.0002366, .2) dat <- data.frame(x1, x2, y) out <- lm(y ~ x1 + x2, dat) out_summary <-
