My understanding is that, in order to use GEP, you have to provide the LLVM code with the struct layout, i.e., build a StructType object. In my case, that struct is declared in C++

I'm following the instructions here: http://clasg.llvm.org/get_started.html and, while running cmake, I get: > CMake Error at cmake/modules/LLVM-Config.cmake:141 (message): > Library `vectorize' not found in list of llvm libraries. > Call Stack (most recent call first): > cmake/modules/LLVM-Config.cmake:54 (explicit_map_components_to_libraries) >

Switching to CodeGenOpt::None reduced the execution time from 5.74s to 0.84s. By just tweaking things randomly, changing to CodeModel::Small reduced it further to 0.22s. We have some old, ugly, pure C++ code that we're trying to replace (both because it's ugly and because it's slow). It's execution time is about 0.089s, so that's the time to beat. Hence, I'd like to

How is having the code that catches all exceptions in a separate function different from what I proposed (putting the try/catch in the thunks)? (Ideally, I want to minimize layers of function calls.)

I've been profiling more; see <https://dl.dropbox.com/u/46791180/perf.png>. One thing I'm a bit confused about is why I see a FunctionPassManager there. I use a FunctionPassManager at the end of LLVM IR code generation, write the IR to disk, then read it back later. Why is apparently another FunctionPassManager being used during the JIT'ing of the IR code? And how do I

Using the LLVM C++ API, if I want to create an array via an Alloca instruction like: Value *a = ir_builder.CreateAlloca( my_type, my_size ); and then I want to initialize each element of the array with values computed elsewhere like: for ( vector<Value*>::const_iterator i = v.begin(); i != v.end(); ++i ) { builder.CreateStore( *i, a ); // How do I increment 'a' to point to

Hi, I'm working on a set of demo files for a package, and I'm having a problem because I have two demo files (one called "logit", the other called "blogit") and when I type demo(logit), it gives me demo(blogit) instead. (And calls it the the demo for logit.) I've figured out that this is because the demo() function searches through all the demo directories (in

Greetings, I am sure I'm missing the obvious, but my 00Index file in the demo subdirectory is not recognized by R CMD check (the demo runs fine, but I get a WARNING from R CMD check about a lack of demo/00Index file. When I invoke demo() in R I see the name but not description of the demo). Is there documentation (other than 'Writing R extensions') on putting together the demo

Currently demo calls source with a hard coded max.deparse.length = 250 so you can't really see the demo properly in some cases. Note the [TRUNCATED] below. (1) It would be nice if demo passed max.deparse.length (and other args to source). (2) Also a larger max.deparse.length default would be nice to make it less likely one would have to set it in the first place. > R.version.string #

Does R support demo names with spaces? I tried placing a file like "My Demo Name.R" in the demo subdirectory, and placing a line that begins with "My Demo Name" in 00Index, but R CMD check does not like this. It reads the line in 00Index as "My, and it doesn't think there is a 00Index entry for "My Demo Name". I have no problem going back to MyDemoName.R,
