Hi all, I'm trying to use the PPL (Parma Polyhedra Library, bugseng.com/products/ppl) in one of my LLVM passes getting the error: > Error opening > '/home/jorge/SvnReps/Systems/llvm/build/Debug+Asserts/lib/MyAnalysis.so': > /home/jorge/SvnReps/Systems/llvm/build/Debug+Asserts/lib/MyAnalysis.so: > undefined symbol: _ZNK23Parma_Polyhedra_Library13PIP_Tree_Node2OKEv > -load request ignored.

...it just won't make sense to me. Running my analysis by hand on command line is fine and works but because of the repetitive nature of the job I would like to code a function for it. My problem: I would like to read in data from a file in my current working dir. so my code would look like: myanalysis <- function(sample, samplenr){ sample.samplenr <- read.geodata("sample.samplenr", arg, arg etc.) sample.samplenr.results <- someanalysis(sample.samplenr) } problem is that charater values aren't interpretated as they should. Any tips and tricks? This should be fairly simpl...

Hello R-Experts, I've got a question, concerning the automation of a number of regressions (lm) with the help of a loop (for i in ....). The situation is as follows (the code follows after that): I have my data in an access database. I have historical data for 2000 parts, for each of this parts I want to do a regression analysis, so I need to do 2000 regressions (just for one country, there

...vm::Module&) + 270 Segmentation fault I'm using the latest SVN checkouts for both LLVM and llvm-poolalloc. Should I perhaps use the 2.5 branch of LLVM instead? Oh, also, what's the name of the DSA pass that pool allocation runs? I'd like to structure my passes to go "DSA-MyAnalysis-PoolAllocation-MyTransform". Thanks, --Patrick

Hi, so this is my first contribution to LLVM/clang, so I hope I come close to the required coding standards and guidelines. First, I will describe the scenario I want to solve: For a few days, the clang plugin interface allows to execute the a plugin just before the actual main action (e.g., compiling an translation unit). In my case, the plugin we're developing will analyze the AST and
