Hi all, I've started work on a new programming language for which I am considering using LLVM as the backend, and trying to experiment with it using the Kaleidoscope demo compiler. Taking the full source listing from http://llvm.org/docs/tutorial/LangImpl3.html#code and trying to compile it with the provided instructions gives me the following errors: a at a-desktop:~$ g++ -g -O3 toy.cpp

Hi, I want to create a double constant from a float constant, here's my code: auto* constFloat1 = static_cast<llvm::ConstantFP*>(llvm::ConstantFP::get(llvm::Type::getFloatTy(context), 3.1)); assert(constFloat1->getType() == llvm::Type::getFloatTy(context)); auto* constFloat2 = llvm::ConstantFP::get(llvm::Type::getDoubleTy(context), constFloat1->getValueAPF());

Probably you missed to install llvm-dev package with headers for llvm. 2010/1/4 Russell Wallace <russell.wallace at gmail.com> > Hi all, > > I've started work on a new programming language for which I am > considering using LLVM as the backend, and trying to experiment with > it using the Kaleidoscope demo compiler. > > Taking the full source listing from >

Hello LLVM team, our software FluidSIM (www.fluidsim.de) simulates pneumatic, hydraulic and electric circuits. For the mathematical models we use the language Modelica (www.modelica.org). We developed our own Modelica simulator which solves the dynamical created algebraic differential equation systems. One tool is our small JIT compiler, which compiles mathematical expressions like “2*x0 +

Hi, all I'd like to write a code that can build different codes based on LLVM version. Like code snippets in the below. #ifdef __LLVM_29__ PHINode *PN = Builder.CreatePHI (Type::getDoubleTy(getGlobalContext()), 2, "iftmp"); #elif __LLVM_28__ PHINode *PN = Builder.CreatePHI (Type::getDoubleTy(getGlobalContext()), "iftmp"); #else assert ("wrong

I read the tutorial doc and some info of SSA, finally understand it. Thanks for your help. And the segmentation error of loading arguementation occurs, (gdb error info) Program received signal SIGSEGV, Segmentation fault. 0x0855bb68 in llvm::LoadInst::LoadInst(llvm::Value*, char const*, bool, llvm::Instruction*) () code is like follows: //#include necessary header files int main(){

It does take one parameter. Here's the important bits: // My Function extern "C" void print(double X) { printf("%f\n", X); } // Args type std::vector<const Type*>

Hi, I want to use a function defined in c(++)-code from code generated by llvm. For this I use ExecutionEngine.addGlobalMapping(). I started with the JIT execution engine and everything worked, then I switched to the interpreter engine and it stopped working, but only if compiled on a Linux system. More precisely it works if I use llvm 3.8.1 + gcc (Linux) + JIT llvm 3.8.0 + mingw-gcc

Hello I want to transfer value (Value* src) of the type `FloatTyID` to `DoubleTyID`(I need all floats to be saved as 8 bytes).I have tried: builder.CreateCast(llvm::Instruction::FPExt, src, llvm::Type::getDoubleTy(llvmContext),””) I don`t know if I use CreateCast correctly and if this approach is correct at all. Thank you. Yakov -------------- next part -------------- An HTML attachment

I tried apt-get install llvm-dev just now, and it says it was already installed, and when I again try compiling toy.cpp, it gives the same set of error messages.

It doesnt work it fails with assertation that cast is invalid .What could be done? On 11/14/11, Duncan Sands <baldrick at free.fr> wrote: > Hi Yakov, that looks correct to me.

Does anyone know how to instrument *double* to <2 x doulbe>**, e.g., 2.2 --> <2.2, 2.2>? For example, I want to change the following IR code %arrayidx1 = getelementptr inbounds [100 x double]* @main.B, i32 0, i32 %i.021 %1 = load double* %arrayidx1, align 4, !tbaa !0 to: %arrayidx1 = getelementptr inbounds [100 x double]* @main.B, i32 0, i32 %i.021 %1 = bitcast double* %arrayidx1

Is there a recommended way to retrieve the original type from an AllocaInst object? For example, I am creating alloca instructions using the IRBuilder interface like: alloca = builder.CreateAlloca( Type::getDoubleTy( context ), 0, variableName.c_str() ); and I place the alloca into a symbol table. Later when I am generating instructions for an assignment operation, I want to check the type of

I sure that is.What could be other reasons for such error?

I'm implementing c style "sizeof()", and I did as http://nondot.org/sabre/LLVMNotes/SizeOf-OffsetOf-VariableSizedStructs.txt illuarstrated, and it works find, here's an example of my implementation: auto *p = builder.CreateGEP(structTy, llvm::ConstantPointerNull::get(pointerTy), constint1); auto *size =

in the tutorial of official llvm doc, chapter 3, it deals with arguement of function as follow: for (Function::arg_iterator AI = F->arg_begin(); Idx != Args.size(); ++AI, ++Idx) { AI->setName(Args[Idx]); // NamedValues is map<string, Value*> NamedValues[Args[Idx]] = AI; and when it try to get the value of arguement, it simply does: Value

Hi Yakov, that looks correct to me. You can also use CreateFPExt which is slightly simpler.
