I'm trying to generate the equivalent of this function dynamically in llvm (a la http://llvm.org/docs/tutorial/JITTutorial1.html) but after half a day of searching I still haven't found how to create the equivalent of the & (address of) operator in the llvm API, more exactly how do I obtain the i8* from the i32 below void fn(int x) { another_fn(&x); } thanks for any suggestions Paul -------------- next...

That's not an example, that's a tutorial, and an incomplete one at that. However I did find the Kaleidoscope example in the subversion repository head. Any clue as to why when we attempt to follow the very simple example in the llvm-2.5 release docs/tutorial/JITTutorial1.html we construct a module state that verifies but then when we ask it to emit, we get a stack overflow from LLVM? Is it supposed to be possible for me to render out an LLVM datastructure that will verify but not render? That is, is this my bug or an LLVM bug? Daniel On Sun, Oct 4, 2009 at 7:27...

Thank you very much for you help, Renato! I read through paper you referred and also this document - http://llvm.org/docs/tutorial/JITTutorial1.html Following these instructions to create successful function I run into some problems: 1) llvm::getGlobalContext() does not exists anymore? "llvm/LLVMContext.h" too? 2) creating instance of IRBuilder don't require template (from tutorial paper - IRBuilder<> builder(block))...

Hi all, I'm a new user to LLVM. Not really sure if this is the correct place to post, since there isn't really any other forums around. Anyway, the issue I'm encountering is that, I was trying out the first tutorial (http://llvm.org/docs/tutorial/JITTutorial1.html). I attempted to do this in another folder that was copied from llvm/projects/sample. I created a new folder called "tut1" in sample/tools/ folder, and the following Makefile. LEVEL=../.. TOOLNAME=tut1 LINK_COMPONENTS += --cxxflags LINK_COMPONENTS += --ldflags LINK_COMPONENTS += --l...

Hello everyone, I am trying to add checkpoints to my IR code. In order to do that I need to add this instruction: call void @m5_checkpoint(i64 0, i64 0) to some of the basic blocks in my benchmark. m5_checkpoint is a function defined for checkpointing in another simulator and is not included in my benchmark source code. So I need to create this instruction and I couldn't figure out how to do

I was referring to <http://www.llvm.org/docs/tutorial/ JITTutorial1.html>, but laboring under the belief that it would first be a good idea to first get through GettingStarted.html, which recommends putting your stuff under "projects" based on "sample", and led me to Projects.html. I'm still stuck on that whole "projects"...

...amples or reading the docs, I suspect that this should be considered to be a bug in the verifier pass: clearly we generated wrong LLVM datastructures somehow and the verifier is not catching it before the emitter falls off a cliff. Please comment.

Hello, I have a simple question. How to create "dummy" function which will have no functionality behind (return nothing and do nothing)? Currently I'm trying to do this: llvm::Constant* c = Module.getOrInsertFunction("dummy", FunctionThatNeedsToBeReplaced.getFunctionType()); llvm::Function* dummy = llvm::cast<llvm::Function>(c); This way I create new function that

I've downloaded and built LLVM 2.2, and I'm now trying to get to the point where I can get through the first tutorial (which seems to assume that you're already to the point of writing code and linking against LLVM). I've found the Projects.html doc page [1], which describes how to set up a project in the LLVM way. But some things are still unclear to me. (Please
