similar to: Fwd: I cannot change value of global variable in LLVM IR using IRBuilder

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

Hi, all I try to get the Instructions where one function use the global variable. for (llvm::Module::global_iterator gvar_iter = M.global_begin(); gvar_iter != M.global_end(); gvar_iter++) { llvm::GlobalVariable *gvar = &*gvar_iter; llvm::errs() << "const global var: " << gvar->getName() << "\n"; for (

Hi Duncan, You're right, global variables use preferred alignment. And - yes, preferred alignment in this case is bigger: 8 instead of 4. NVIDIA's prop. compiler gives 4. However, since CUDA 5.0 ptx modules are linkable with each other, I think alignments for externally visible functions and data should all follow ABI rules. Is there a guide on making tests? I have ~5 pending patches

Hi everyone, I am doing some work with LLVM IR, I need to use LLVM IR to do operation on C variables. Code emission is done by LLVM JIT. That variable is C thread local , for example __thread int* gvar; I think some methods to convert that variable to LLVM IR, (1) use external function I know LLVM IR is able to call an external function, so I can write codes that look like: int* load()

Test cases exist under test/CodeGen/NVPTX (name changed in May). Now that I'm back at NVIDIA, I'm going to be running through the bugzilla issues (thanks Dmitry for the reports!). I have practically the exact same patch here in my queue. :) In this case, I would prefer ABI alignment for compatibility with the vendor compiler. It should work either way, but I do need to audit the

Dear all, I'm attaching a patch that should fix the issue mentioned above. It simply makes the same check seen in the same file for global variables: emitPTXAddressSpace(PTy->getAddressSpace(), O); if (GVar->getAlignment() == 0) O << " .align " << (int) TD->getPrefTypeAlignment(ETy); else O << " .align " <<

Hi, I am brand new to R and not familiar with the language, though I have been reading the manuals and making some slow going progress. I am working with some source code from a Global Vector Auto -Regressive program written by Ranier Puhr from the R-forge group. I need help interpreting the processes of the following code. I am going to post in parts since it's pretty long: GVAR

I am trying to change this define void @main(float* noalias %arg0, float* noalias %arg1, float* noalias %arg2) { entrypoint: %0 = bitcast float* %arg1 to <4 x float>* intothis define void @main(float* noalias %arg0, float* noalias %arg1, float* noalias %arg2) { entrypoint: %0 = getelementptr float* %arg1, i64 0 %1 = bitcast float* %0 to <4 x float>* I must be close but

Not to distract, but the word, `procedurization' is not an English word. It's just leaping out at me when it is either procedure(s) (noun) or proceduralize (verb). Even processes would make sense. I couldn't help myself because the word was distracting. - Marc P.S. Not that my vote counts, but I'm more in the camp of Hal whose approach to tackling the parallelization

Hi all, I have a patch that would potentially help Objective-C 2. In the "make_decl_llvm()" in llvm-backend.cpp, there is code to search through the already generated global variables. Objective-C goes through this code twice with the same identifier. The first time, is to create meta-data for a "property". The second time is to add a reference to that property into the

Hello, Calling `replaceUsesOfWith` with a value in a different addrspace does not keep the addrspace of a GEP consistent. Is this known? Is this a bug or expected behaviour?

Hi, I need to pass some arguments to CreateCall function (as Value *). For example, I need to pass a 64 bit integer (with a value I calculate). How can I convert the 64 bit integer to a value * in order to pass it? Thanks a lot, Tehila. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi All, We'd like to make a proposal for OpenMP representation in LLVM IR. Our goal is to reach an agreement in the community on a simple, complete and extensible representation of OpenMP language constructs in LLVM IR. Hopefully, this would serve as a common ground and would enable further development of OpenMP support both in Clang and LLVM compiler toolchain. We seek feedback on the

Hi, I'm trying to define a mutable variable, outside functions. The code below is trying to evaluate an expression much like "x = 1" at the module level in Python. It appears that when it tries to JIT the function there is an error because there is no storage allocated for 'x'. How do I do that? thanks, Rob ----- dumped IR ----- ; ModuleID = 'repl-module' %0 =

Hello, FYI, this is a bug http://llvm.org/bugs/show_bug.cgi?id=13324 When compiling the following code for sm_20, func params are by some reason given with .align 0, which is invalid.

Hi, I am executing a C program using JIT. When the program exits, the control comes back to my program which initiates the JIT. Now, I want to read the value(not the LLVM nomenclature) of a global variable (not the LLVM nomenclature). I am able to get the global variable, using the following command: GlobalVariable *my_global = Mod->getNamedGlobal("MY_GLOBAL"); I want to know the
