similar to: [LLVMdev] Creating a global variable in JIT context

Do you use load to get the value of V? If not then you probably return i32* instead of i32.

Hi, I'm Ryo Ota. I'm using LLVM 3.8.1. I have a quesion about inlining function in C++ API. I'd like to inline some functions in a module in the same way as `opt -inline` command. But my C++ code didn't work what I want to do. For example, by using `opt -inline` command,`main.ll` is converted into the `inlined.ll`(`opt` command worked what I want to do) [main.ll (Not inlined)]

The dump from the function I'm running: define %object_structure @0() { entry: ret %object_structure { i8 0, %object_union [double 5.000000e+00, double false] } } the only output I get after the runFunction() call is: UNREACHABLE executed! Stack dump: 0. Running pass 'X86 DAG->DAG Instruction Selection' on function '@0' I just noticed that my union seems to look like

What does this error mean? I'm getting it from an ExecutionEngine::runFunction() call. The function I'm passing it was run through verifyFunction() right before the runFunction() call. I can't seem to find anything that tells me what causes this, only specific (but seemingly unrelated to my problem) cases of it happening. -------------- next part -------------- An HTML attachment was

Hello; Thanks to Eli for the pointer to the ConstantDataArray::getString() fucntion. Now I am trying to declare a global char array with the content "hi" and call a function "print" (which takes a char pointer and return an insteger. I am doing the following in the code - Function Creation: PointerType* array = PointerType::get(IntegerType::getInt8Ty(getGlobalContext())

I've built chromium with " -fprofile-instr-generate -fsanitize=address" -- the performance looks good! The file format from r198638 is indeed rudimentary. Do you already know how the real output format will look like? Just to summarize what I think is important: - minimal size on disk, minimal amount of files - minimal i/o while writing to disk, no lockf or some such -

Tthe IRBuilder APIs for unions or unions in general? Either way, I was using unions as a temporary solution for a problem I was too lazy to fully figure out anyway.

I have an optimization pass (FunctionPass) where I need to add global constructors. For cleaness sake I decided to add these in my own module. My module is created in my FunctionPass constructor: MyPass() : FunctionPass(ID), myModule("my_module", getGlobalContext()) {} I generate an llvm.global_ctor global variable in my module, and I add my global constructors

I am new to llvm so I might be missing a critical step. My system is Fedora 12 but this also happens in Mac OS X 10.6.2. Here are the steps I used to compile llvm: export TARGETS=x86,x86_64,cpp export INSTALLDIR=/home/rovitotv/llvm ../llvm-2.6/configure --prefix=$INSTALLDIR --enable-bindings=none --enable-targets=$TARGETS --enable-optimized --with-llvmgccdir=$INSTALLDIR

First, you have to call llvm-g++ to use the llvm-gcc front end, but it doesn't matter here. I'd like to suggest that you use pastebin to put your code and the send us the link, so that we can download it. The problem is that TheExecutionEngine is set to NULL (maybe because of a previous error), but it will be really better if you use pastebin. On Wed, Feb 17, 2010 at 6:01 AM, Todd Rovito

I followed what you said and called verifyModule() with the AbortProcessAction option. verifyModule() returns false, but does not abort and does not print out any information about what caused the verification to fail.

I also tried iterating through the functions of the module and calling verifyFunction(), which also returns false, but does not cause an abort or report anything to stderr about what caused the verification to fail. From the doxygen for verifyFunction() and verifyModule(), it seems like they both should print information to stderr if the verification fails and should abort opt if

I am programmatically building some functions in intermediate representation, and trying to verify them, but the verifier always reports that there is a problem, and I can't see why. Minimal test case: #ifdef _MSC_VER #pragma warning(disable : 4141) #pragma warning(disable : 4530) #pragma warning(disable : 4624) #endif #include <llvm/IR/IRBuilder.h> #include <llvm/IR/Verifier.h>

Hi, I have this call instruction to printf inserted which is causing an assertion failure. Any pointers to where I am wrong : Code Dump : Function *printFn=M.getNamedFunction(std::string("printf")); Constant *str=ConstantArray::get("Value : %d\n"); std::vector<Value *> Args(2); std::vector<Constant *> GEPIndices(2);
