Hi Cristianno, This problem has been around for a while, ourselves we solve it with the following patches: https://hpcforge.org/scm/viewvc.php/trunk/patches/llvm.gpu.patch?root=kernelgen&view=markup https://hpcforge.org/scm/viewvc.php/trunk/patches/llvm.patch?revision=591&root=kernelgen&view=markup Please feel free to apply them, they *should* work for you even with the latest llvm

Hello again, Thanks for the responses =) Dmitry, I have two points to comment: - First, I applied these two patches, and the .cbe.c file came out ok, except for one little thing -- the global variable was created with both modifiers: static and extern. Then, I just added a single guard to prevent this to happen (in a case of a variable having local linkage, the "extern" part was not

Thank you for answering my E-mail. According to http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-March/047989.html, I open the link: https://hpcforge.org/scm/viewvc.php/trunk/patches/llvm.gpu.patch?root=kernelgen&view=markup https://hpcforge.org/scm/viewvc.php/trunk/patches/llvm.patch?revision=591&root=kernelgen&view=markup The result is: SCM Repository An Exception Has Occurred

Hello guys, So, I'm stucked in a problem involving a Function and a derived class. Well, I was refactoring part of my pass code, and created two classes in this process that are interesting here: class A and class B. Class B inherits from class A; on the other hand, class A has some pure virtual methods (already implemented in class B), and a Module, that holds only one auxiliary function (a

Hi Cristianno, Thank you, it works :) with an extra cast:                                     Value *v ......                                     ConstantInt* RR = (ConstantInt *)v;                                     uint64_t VV = (RR->getValue()).getLimitedValue();                                     errs()<<"\nRR  "<<VV<<"\n";

Hello again, So, after some changes, I inserted intentionally values with use in other modules, and I get the following error: While deleting: i1 % Use still stuck around after Def is destroyed: %c = phi i1 [ false, <badref> ] [...] Assertion failed: (use_empty() && "Uses remain when a value is destroyed!"), function ~Value, file

Hello there, I'm writing a transformation pass for LLVM, and I hoped to use dce to clean up the resulting code after my pass. I just have some questions about LLVM's dce implementation. Well, my transformation is a function pass, and, after the changes are made, some instructions are not needed anymore. In order to easily get rid of those instructions, I'm setting all their uses to

Hi there, I'm trying to get a list of predecessors of a BasicBlock. I'm using a code similar to that on here (http://llvm.org/docs/ProgrammersManual.html#iterate_preds), but it appears to be more nodes been iterating that it should. Now, when I print out the llvm IR, I get something like: […] while.body: ; preds = %7, %while.cond […] for a code that

Hello there, I'm writing some LLVM passes, and just ran into an interesting situation: now, I don't know if I misunderstood the way doFinalization is supposed to work, but I hope someone could help =) One of the transformations I wrote needed to replace some instructions within the code, so I needed to clean up the code after the process was completed. The pass basically swapped some

Hello again, First of all, thanks for all the answers =) they really helped a lot =D *Have you verified that some other pass is not adding the function declarations back in after your pass is executed (e.g., by using the -debug-pass=Executions argument to see what passes run after your pass)?* I considered that for a moment, but I realized that wouldn't be possible for two reasons: I

Hello ! This may be a trivial question, but I cannot get fields from a Value type. If my Value is i32 1, how can I store 1 in a different structure (an integer) ? For the type, I have getType(). For the value, I see no method in Value.h. I tried to cast to ConstantExpr and then to get operands, or cast to ConstantDataArray and then use getAsString(), but is not working. How should I get the

Hi, First of all, please note: as of v3.1, C backend has been thrown away for being "buggy" and "unmaintained". Several months ago there was a similar question, and it was solved. Please see the patch attached here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-March/047989.html Best, - D. 2012/8/18 xiaoyaollvm <xiaoyaollvm at 126.com>: > In llvm3.0,I use the llc

In llvm3.0,I use the llc to convert the IR to C code, But the code lack key words like "struct", Who can tell me how to modify the CBackend, 3Q ^-^ -------------- next part -------------- An HTML attachment was scrubbed...

Hello there, I'm trying to use a simple implementation of a queue (my own implementation of it, actually), and I'm trying to use the functions defined on my queue class inside some llvm-ir code. Unfortunately, the names of the functions are being messed up, then I created some function wrappers just to avoid having to deal with the C++ weird function renaming. So, to easily wrapper the

Hi Rinaldini, In order to find information about loops inside a given function you should use something like "LoopInfo *LI = P->getAnalysis<LoopInfo>()", remembering to add "AU.addRequired<LoopInfo>();" to your getAnalysisUsage method. If the function you are interested to is not located in the module being compiled (if you created it as an auxiliary function,

Dear All, I'm trying to add a new alias analysis to the alias analysis group in LLVM 3.2. This new pass is linked statically into a tool that lives outside the LLVM source tree, so I'm trying to avoid making patches to the LLVM sources. I've added the INITIALIZE_AG_PASS_BEGIN() and INITIALIZE_AG_PASS_END() code to the pass, manually scheduled it before the
