search for: stringconstant

Does the C API have an equivalent of stack storage? Via the C++ APIs one can shove the string constant on the stack via a store instruction operation on an alloca instruction--the address needed is the alloca. For example: llvm::Value* stringVar = builder.CreateAlloca(stringConstant->getType()); builder.CreateStore(stringConstant, stringVar); The stringVar is your address.

Hi, I've read http://llvm.org/docs/LangRef.html#t_array and http://llvm.org/docs/GetElementPtr.html and if I've understood right there are no operations that act directly on arrays - instead I need to use getelementptr on a pointer to an array to get a pointer to an array element. I also understand that there is no 'address of' operation. As a result I can't figure out how to

Hi, I'm pursuing M.Tech course. As a part of the project work i'm using LLVM as back-end. My project area is "Enhancing the performance of V8 javascript engine using LLVM as a back-end". Now i'm writing code for shift left(SHL) operator. I had my own Value Structure .. it's like this Struct Value { void *val ; char type; } The "char type" holds

Hi Sarath, It would have really helped if you had removed the commented out code and inlined the calls to your homemade helper functions before sending it... You are doing this, in LLVM IR: %0 = getelementptr %Value* %firstArg, i32 0 ; i8** %1 = load i8** %0 ; i8* %2 = bitcast i8* %1 to i64* %3 = getelementptr %Value* %secondArg, i32 0 ; i8** %4 = load i8** %3; i8* %5 = bitcast i8* %4 to i64*

Yeah, that's the fault...got the answer...... Thanks James for the help... Struggling with this for so many days.......
