Presumed bug found in SCROLL_GetPtrScrollInfo
Hi all. We have a win32 application linked to Far Point's Spread32 library; the application crashes when referencing a NULL pointer returned by GlobalLock, but obviously it runs perfectly under win98SE (see previous post about GetWindowLongA) . The behaviour of SCROLL_GetPtrScrollInfo, with nBar parameter = SB_CTL, is to return wndPtr->wExtra as it were a pointer. Actually we found that,

A bug in DependenceAnalysis?
Hi Philip, Thanks for checking! I'm running my own Foo pass that registers DependenceAnalysisWrapperPass as a prerequisite and then I run it like so: opt -load libfoo.so -foo example.bc This is LLVM 3.9.

How to find memory utilization percent of kvm guest?
I currently use following approach but its failing Find Max memory using following API         vdgiRet = virDomainGetInfo(domPtr, infoPtr);         memTotal = infoPtr->memory; Find current utilization using following API                 rVal = virDomainMemoryStats (domPtr, memStats, VIR_DOMAIN_MEMORY_STAT_NR, 0) ;         for (i = 0; i < rVal; i++)         {             if

A bug in DependenceAnalysis?
Hello llvm-dev, I'm running a pass that uses the result of llvm::DependenceAnalysisWrapperPass to compute the dependencies between all instructions of a loop. I have the following two examples of code I wish to analyse: example A: ``` void move_one(int *A, unsigned n) { for (unsigned i = 0; i < n-1; ++i) { A[i] = A[i + 1]; } } ``` and example B: ``` void move_one_alt(int *A,

A bug in DependenceAnalysis?
Hi Philip, I forgot to mention that I was ignoring loop-independent dependences. If I don't I get an inconsistent, ordered, anti, loop-independent dependence and an inconsistent, ordered, flow, loop-carried dependence for example A. At the same time I get just a consistent, ordered, anti, loop-independent dependence for example B. Here's the .ll code for example A: *; Function Attrs:

wine: Unhandled page fault on read access
Hi, Thanks for the tips. I tried with winetricks but gave me a problem to get this installed, I finally did it semi-manual. As you said I could open an sample set but nothing more. I then upgraded to wine 1.3.8 today. Will this overwrite the winetricks dll's or not? I could start the application open and save a dataset although they seem to be empty!?. I started to move deeper into the

UI regression
Hi, Earlier this year I "upgraded" from wine 20010510 to 20011226 in order to see if some kind of resource leak was fixed which caused screen redraws to get progressively slower and slower and slower and slower, .... That was fixed but there seemed to be a significant number of graphics and UI regressions. I've just upgraded to 20020228 to see if things were any better and within

[LLVMdev] Loop carried dependence analysis?
Hello everyone, I intend to build a pass to profile some benchmarks for loop carried dependencies. At first I tried looking at LoopDependenceAnalysis.{h,cpp} but the files were removed for some reason. So I continued with the DependenceAnalysis pass. But the flow, anti dependence, etc methods are only reporting sequential and not loop carried dependencies. Does LLVM support loop carried

Voice from one call carried on to next call
I have set up asterisk with an ISDN card using i4l. When I place a call from ISDN to a SIP client, there is about a one-second delay from a word is spoken to it is heard at the other end. The funny thing, is that the last second or so of each call is saved somewhere in the depths of Asterisk and then played back at the beginning of the next call. I have read it is a known problem, can

Frequency range carried by speex
I've looked around and not found details on the expected frequency range the Speex codec can be expected to carry. Is there any documentation available or a table of some sort that has been compiled which would give an indication of the frequency range based on the various compression options in speex?

last observation carried forward +1
Hi R-helpers I'm looking for a vectorised function which does missing value replacement as in last observation carried forward in the zoo package but instead of a locf, I would like the locf function to add +1 to each time a missing value occurred. See below for an example. > require(zoo) > x <- 5:15 > x[4:7] <- NA > coredata(na.locf(zoo(x))) [1] 5 6 7 7 7 7 7 12 13

[LLVMdev] Loop-carried Dependence
Hi, Does anyone know if there is any existing code I can use to do a loop-carried dependence analysis for LLVM IR programs? I searched the mailing-list archive and it seems like someone planned to implement a loop dependence analysis pass in March. I'm just wondering if this project is ongoing/finished or if there is other projects that may have the code I'm interested in. Thanks!

vectors levels are carried through to subsets...
I have a dataset. Initially, it has 25 levels for a certain factor, Description. However, I then subset it, because I am only interested in 2 of the 25 factors. When I subset it, I get the following. The vector lists only the two factors, yet there remain 25 levels: > Quadrats.df$Description [1] Emergent 25x75 Emergent 25x75 Emergent 25x75 Emergent 25x75 Emergent 25x75 Emergent 25x75

Extracting the names of the variables that creates loop-carried dependencies
Hi Michael, Thanks for your answer. Checking the indexes looks as an another straightforward approach to identify the actual loop-carried dependencies. What is not clear to me still is how it looks like the code to extract the ScopArrayInfo pointer from the user part.

destory Test Case Messes up all tests
I am trying to create unit tests for my users model but when I add a test that destroys a user, that user is not available in any of the other test. If I remove the test that destroys the user all my other tests work again. All the fixtures are suppose be reloaded between tests right?

help with using last observation carried forward analysis for a clinical trial please
Hi, I have a series of id's with multiple visits and questionnaire scores. This is a clinical trial that will be analyzed using the last observation carried forward method. In other words, in order to comply with intent to treat analysis when many subjects withdraw, data points for the last visit must be generated and filled in with the last observation. The ultimate goal is to tabulate the
