Right, C bad habit ;) Fixed. >> - const Type *Ty = Type::getInt64Ty(SI->getContext());

Evening, I was writing some code that tried to insert calls to the llvm.annotation intrinsic function, which has a signature of (i32, i8*, i8*, i32). The code is below. void addAnnotation( BasicBlock *block, Function *F) { string foo = "foo"; string bar = "barr"; Type *charTy = Type::getInt8Ty(block->getContext()); ArrayType *s1Ty =

Ok, I've tracked down the problem I've had bootstrapping llvm-gcc. The culprit is in TreeToLLVM::EmitMemCpy: void TreeToLLVM::EmitMemCpy(Value *DestPtr, Value *SrcPtr, Value *Size, unsigned Align) { const Type *SBP = PointerType::get(Type::Int8Ty); const Type *IntPtr = TD.getIntPtrType(); Value *Ops[4] = { CastToType(Instruction::BitCast,

I want to create a vector version sqrt as the following. Value *Approx::CreateFSqrt(IRBuilder<> &builder, Value *v, const char* Name) { Type *tys[] = {v->getType()}; Module* M = currF->getParent(); Value* sqrtv = Intrinsic::getDeclaration(M, Intrinsic::x86_sse2_sqrt_pd); CallInst *CI = builder.CreateCall(sqrtv, v, Name); return CI; } Here is Value *v is <2 x

Hi, I tried creating variable argument intrinsics which are to be placeholders for some instructions which should not be executed by the backend. Kindly help me with the errors in my "migrate_begin" intrinsic creation //Additions made to Intrinsics.td file: def llvm_migrate_begin : LLVMType<iAny>; def int_migrate_begin :

Thanks, Shahid. It is fixed now.

Hi, I'm trying to use exception control by LLVM. In the demo page, I got : declare i8* @llvm.eh.exception() nounwind But, when a try to emit the code by llvm engine, the name is generate with the sufix .132 ( llvm.eh.exception.132 ) and the Function::getIntrinsicID abort the program. It was so : Intrinsic::getDeclaration(llvm_module,Intrinsic::memset,&Tys,1); Now, it's

Hi, Thank You for the advice and we were able to solve that problem by the following modifications to the Instrinsics.td file. But I now have an "Invalid Intrinsic name" error This error occurs presumably because the created intrinsic is named: llvm.migrate_begin.i32 Intrinsics.gen checks for a string length of 18 (i.e. the length without the .i32). Kindly help me through it.

In the following scrap of code (pared down from actually useful code), the func->dump() command segfaults iff the commented-out line is uncommented. This is with llvm 3.0. I'm only dipping my toes into the waters of llvm for the first time, and have no idea what I am doing incorrectly. In actual code, I would be wanting to call the memcpy intrinsic eventually, of course. int main(void)

I would like to use intrinsic with different address space. I defined an intrinsic (used to represent à specific instruction of my target) with a pointer in its arguments, but when calling this intrinsic, if the pointer is not in the generic address space (ie AddrSpace 0), an error occurs ("bad signature"). How can I specify the address space in the intrinsic definition ? Thank you.

Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

I also tried the following, with no compilation errors, but segfault, core dumped: *LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } llvm::ArrayRef<Value*> bla = values[size]; is->setMetadata("path",MDNode::get(C,bla));* On Fri, May 3, 2013

Hi, I want to access an array in my instrumentation code. For example: GlobalVariable: int *counter; //counter the number of load/store operations in run-time int *counterArray; //record the load/store addresses //increase the counter if a load/store is performed std::vector<Constant *>index(2); index[0] = Constant::getNullvalue(Type:getInt32Ty(Context)); index[1] =
