hello everyone,recently I write a package for R call Julia through Julia C API https://github.com/armgong/RJulia now the package can do 1 finish basic typemapping, now int boolean double R vector to julia 1d-array is ok,and julia int32 int64 float64 bool 1D array to R vector is also ok. 2 R STRSXP to julia string 1D array and Julia string array to STRSXP i...

Dear Community, in an earlier post, students working on LLVM were asked to provide a short report on their GSoC project. in the following I want to give an overview on the current status of my GSoC project and outline my next planned activities. Since my mentoring organization is Julia, I also send this to the according mailing list. *1. Activities so far:* As described in my proposal [1], I am working on making available Polly's optimizations on Julia. Within the pull-requests [2] and [3] I integrated Polly into Julia's LLVM-based JIT infrastructure. Polly can now be...

Folks, We are contemplating holding a Birds of a Feather session titled "Julia and LLVM: Implementing a fast dynamic language for technical computing" at the LLVM 2012 European Conference on April 12-13 in London. http://llvm.org/devmtg/2012-04-12/ Would this be of interest to the LLVM developer and user community? It would be great if you could drop me a line. It wil...

Dear LLVM contributors, my name is Matthias, I am a graduate student majoring in computer science at the Vienna University of Technology, and I am glad to be one of this year's GSoC students who work for the Julia foundation. Julia is a relatively young programming language that uses LLVM for just-in-time compilation and the goal of my project is to integrate Polly in this environment to enable polyhedral optimizations for Julia programs. On the one side this will require changing Julia's LLVM IR generat...

Hello, I'm trying to fix a long standing issue we are having in Julia where when the file information switched, we weren't recording that correctly, so line information showed up in the wrong file. Basically we would always create a scope with the DISubprogram and the given line number. What I tried was to change the scope to be a DIFile instead so we'd get t...

Hallo! Is there a possibility to plot a number line in R? I would like to display 3 different Intervals on the same number line. Ideally, it would be possible to add a name to each number (e.g. Interval 1, lower cut-off...and so on). I have not found a command for this. Thank you for your help.

...with asan enabled (I also updated to trunk, but not sure if that's related). However, it's totally possible that I missed a step that I took back when I set this up for me, so I might be doing something very stupid.

My purpose in mentioning the Julia language (julialang.org) here is not to start a flame war. I find it to be a very interesting development and others who read this list may want to read about it too. It is still very much early days for this language - about the same stage as R was in 1995 or 1996 when only a few people knew abo...

I'm looking for a sanity check on extending SLP Vectorizer to deal with aggregates. I'd like to vectorize Julia tuple operations. The Julia compiler lowers tuples to LLVM arrays, not LLVM vectors. I've tried making Julia lower tuples to LLVM vectors, but that hurt performance when SLP Vectorizer was not applicable, because of extraction/insertion overhead. I.e., the Julia lowering is too early to make...

Hello everybody, I've run into some strange behavior with memory sanitizer that I can't explain and hope somebody with more knowledge of the implementation would be able to help me out or at least point me into the right direction. For background, I'm using memory sanitizer to check Julia (julialang.org), which uses (or at least will once I track down a few bugs) MCJIT for the code compilation. So far I have rebuilt the runtime and all dependencies (including LLVM, libcxx, etc.) with memory sanitizer enabled and added the instrumentation pass in the appropriate place in the julia co...
