search for: thepointer

...I am writing a JIT compiler for a subset of the Matlab language and as a part of my implementation, I would like to be able to pass a constant pointer to a native function I'm calling. Right now, this is what I do: llvm::Constant* constInt = llvm::ConstantInt::get(llvm::Type::Int64Ty, (int64)thePointer); llvm::Value* constPtr = llvm::ConstantExpr::getIntToPtr(constInt, llvm::PointerType::getUnqual(llvm::Type::Int32Ty)); builder.CreateCall(my_function, constPtr); The resulting IR call looks like this: call void @nativeFunc(i32* inttoptr (i64 146876396 to i32*)) I'm just wondering if there...

You can insert a declaration of the function into the IR, then

Dear experts, I am learning llvm by reading documents and have a question to ask. The following is the example of code generation that I created. [[a [10.00]] > [3.00]] ; ModuleID = 'ExprF' define i1 @expr(double* %record) { entry: %0 = getelementptr double* %record, i32 0 ; <double*> [#uses=1] %1 = load double* %0 ; <double>
