The reason is simply: we're emitting a call to __muldc3 with AAPCS VFP calling convention, however, the function expects softfp (AAPCS) calling conv and reads garbage from GP registers. I'm working on fix.

Has anyone converted llvm/projects/test-suite to use the llvm assembler instead of gcc? If so, what was needed to change and how? My assumption is that this would be a good way to test the llvm assembler. Jack -------------- next part -------------- An HTML attachment was scrubbed...

Dear R users, I have some trouble using the allEffects() function to compute and display effect plots for a linear model. My data is quite simple, it concerns effects of 3 treatments on the tumoral volume of mice. vTum codes for the qualitative initial volume, from small to big, temps is the time in month since beginning of treatment, and S?rie codes for the batch. Data is unbalanced. >

Hi all, We have 4 outstanding tests on clang-mergefunc-x86_64-freeBSD9.2 builder. I have introduced issues for them in bugzilla: http://llvm.org/bugs/show_bug.cgi?id=18089 http://llvm.org/bugs/show_bug.cgi?id=18056 Since we have opened issues for these tests, can we add them to ignore-list for this builder? It allows faster catch and fix other failures (if we get them). I also wandering, may be

Is there code available to decompose interactions involving at least one nominal factor with more than 2 levels as described, e.g., by Tukey or by Mandel (1971, Technometrics, 13: 1-18)? Tukey's model: E(y[i,j]) = mu0 + a[i] + b[j] + c*a[i]*b[j], estimating a, b, and c so sum(a) = sum(b)= 0. Mandel essentially describes a singular value decomposition of the interaction. Thanks,

Hey everyone, Not sure if anyone had tried this but I managed to get LLVM and clang to build on Nexenta Alpha 7. This is an OpenSolaris/GNU OS. There wasn't much to change for LLVM, except "#undef"ing a lot of x86 register name equivalents and the like (ie. EAX,ESP,CS,FS...). There were a couple of similar undef's needed for clang, as well. The clang testsuite ran fine except

Hi Chandler, That's embarrassing how weird this part of clang is. I have a provisional patch which fixes the problem but underlines clang's problems. I will submit it tonight for comments. суббота, 18 октября 2014 г. пользователь Chandler Carruth написал: > > On Fri, Oct 17, 2014 at 7:51 AM, Anton Korobeynikov < > anton at korobeynikov.info >

Newbie of course, and having trouble finding answers in the plethora of documents and forums. I can't seem to set up my config correctly so that my windows drives and cdrom are properly recognized by winefile. I put lines in for C - fake windows D- real windows E-cdrom P-Partition that has my windows based program files(this drive segfaults 139 depending on which way I go into it)

I have a data frame with 2 columns, one for day and one for average. The day starts at 97 all the way to 279. I want to subtract day 98 average- day 97 average, then day99 average -day 98 average and so on down my list, creating another column with the subtracted results. I have: Day DailyAverage 1 97 0.6076782 2 98 0.7121478 3 99 0.8059347 4 100 0.9545806 5

Dear Colleagues, John Mandel ( Chain block designs with two-way elimination of heterogeneity. Biometrics 10, 251-272 ,1954). extended the class of chain block designs (Youden & Conner (1953) to elimination of both row and column (blocks) effects. These experimental designs can be useful in engineering and other fields. I am having difficulty obtaining his adjusted treatment means in his

How does one define PDFs as yet undefined in R, such as the ex- gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF would then be the convolution of an exponential PDF, dexp(), and a normal, dnorm(). Kindly cc me in your reply to r-help.

I am getting ready to install Asterisk and I was looking into the Polycom IP600 phones. I spoke with Polycom sales to verify the multiple line appearance and they said it would work. More specifically, if lines 1-3 all contain the same SIP registration info, the Polycom will only send out 1 SIP registration to the server and then handle the calls ringing on multiple lines. I was wondering if

Great, thanks! How much work do you think it will take to bring it up to date with the LLVM IR, except *ignoring* first-class structs and arrays for now? I believe llvm-gcc does not generate those in most cases and we can do a lot without supporting those. What else is missing relative to the current LLVM IR? Thanks, --Vikram Associate Professor, Computer Science University of

Hello; I was able to build and install llvm(3.0) under Ubuntu 11.10 (using the ./configure script found under llvm source, and then make and make install). While configuring, I gave --prefix as a directory where I would like llvm to be installed. I did not give --with-llvmgccdir and the --enable-optimized argument to configure. Because 3.0 doesn't come with llvmgcc source/binaries and I

Hi All ! Recently in the mailing list there was the question about benchmarking LLVM. I was told that LLVM get's benchmarked in the nightly test. While this is true, I wanted to have a tool to compare LLVM against other compilers, so I wrote a little python program (attached) that filled my need. It is completely outside of the LLVM makefile framework, but this stems from the fact that I

Hello everyone, A little background first: I have collected psychophysical data from 12 participants, and each participant's data is represented as a scatter plot (Percieved roughness versus Physical roughness). I would like to know whether, on average, this data is best fit by a linear function or by a quadratic function. (we have a priori reasons to expect a quadratic) Some of my

LLVMers, 2.6 pre-release2 is ready to be tested by the community. http://llvm.org/prereleases/2.6/ If you have time, I'd appreciate anyone who can help test the release. To test llvm-gcc: 1) Compile llvm from source and untar the llvm-test in the projects directory (name it llvm-test or test-suite). Choose to use a pre- compiled llvm-gcc or re-compile it yourself. 2) Run make check,
