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

Hi LLVM developers, After Remove int_x86_sse2_psll_dq_bs and int_x86_sse2_psrl_dq_bs intrinsics. The builtins aren't used by clang. https://reviews.llvm.org/rL229069 there was no Intrinsic::x86_sse2_psrl_dq any more, then how to migrate: Function *F = Intrinsic::getDeclaration(TheModule, Intrinsic::x86_sse2_psrl_dq); Result = Builder.CreateCall(F,

Dear All I'm trying to create storeInst using StoreInst *SI = new StoreInst(val, AI, BB); AI is an alloca instruction previously created, BB is the basicBlock I want to put instructionsi in. Val is the value to store. I've created val from a genericValue like this: Value* val = ConstantInt::get(getGlobalContext(), Result.IntVal); Result is the genericValue However I keep getting

Hi, I am trying to write a simple interpreter. I am trying to generate LLVM IR for assignment operation. The code for the generation part looks like this llvm::Value* codeGenSymTab(llvm::LLVMContext& context) { > printf("\n CodeGen SymTab \n"); > Value *num = ConstantInt::get(Type::getInt64Ty(context), aTable.value, > true); > Value *alloc = new

Hi, I'm currently working my way through the tutorial with LLVM 3.9.1 on Windows (finished chapter 4) and stumbled over a few things which could be improved: - "LLVMContext" does not exist as a variable -> "TheContext" - Chapter 3: 5 times - Chapter 4: 1 time - Chapter 5: 4 times - Chapter 6: 2 times - Chapter 7: 2 times 3.4. Function Code

Attached is the target independent llvm.atomic.barrier support, as well as alpha and x86 (sse2) support. This matches Chandler's definitions, and the LangRef patch will just restore that. Non-sse2 barrier will be needed, I think it is "lock; mov %esp, %esp", but I'm not sure. Any objections? I'll take a hack at the front end support for __sync_synchronize after this

hey, so I'm writing in cpp. the documentation says that TheModule -> getDataLayout should return const DataLayout, but instead it is returning std::string. I require it to return DataLayout, as I generalize my function pass manager to accept the DataLayout constant as an argument, it being the only thing in common amongst both the ExecutionEngine and the Module class. Any pointers to

Hello everybody, my problem is, that I want to get an array of pointers to all local variables in a function. This array will be used for transfering these Variables to another execution engine. I've code which generates this array, and a pointer to the target field of the array. name = variables.fname + "_pointerArray"; Instruction* pointerArray = new

Hi I want to insert some functions into the llvm bitcode ir files. So I use IRBuilder and CreateCall(). But it how error : inlinable function call in a function with debug info must have a !dbg location. I don't know what DebugLoc should I give the new CallInst to setDebugLoc. I Create this CallInst , so this CallInst doesn't hava so-called "DebugLoc" mapping to the source

Hello All I 'm studing LLVM/Clang and trying to follow the Kaleidoscope tutorial (Release 2.6 version). I found some minir docu-bugs and added them to Bugzilla. However, Now I found a show-stopper for me, the toy (v4) demo does build, but does crash, on any input. Even a simpe ';'! Looking into the (demo-code) found the that the JIT can't be build/ created,/loaded/... Which

Hello I have the following scenario, and I am not sure why the performance is so bad (take 30 minutes to complete with very simple generated functions): 1. Create module 2. Do something like EE = EngineBuilder(theModule).setEngineKind(EngineKind::JIT).create(); 3. Create a function in the module: theModule->getOrInsertFunction(..) 4. Execute 1000 times the function using

This should have gotten an assertion failure in a compiler built with assertions, surely...

Hi, I'm having a hard time finding an answer to what I assume is a very basic idea. I'm trying to produce this llvm code using the LLVM api: %myString = alloca [13 x i8], i32 13 store [13 x i8] c"Hello world.\00", [13 x i8]* %myString %tmp1 = getelementptr [13 x i8]* %myString, i32 0, i32 0 %tmp2 = call i32 (i8*, ...)* @printf( i8* %tmp1 ) nounwind A simple Hello

Hi, I want to convert a function pointer call in the IR of MPlayer to a function call. For example, I have the following line: ... %10 = tail call i32 %7(%struct.demuxer* nonnull %0, i32 %1, i8* %2) #7, !dbg !863222 ... I want to set the target which is stored in %7 to a real function called "demux_lavf_control()" with the following definition: ... define internal i32

Hi all, building current llvm-gcc-4.0 TOT(Revision: 42128) with current llvm (Revision: 42128) on 8.10.1 Darwin (x86) fails with the following message.
