We tested on 3.4.2 and 3.5.1. Later versions are slightly problematic to test since they don't compile with VS2010. Do you happen to know if it's fixed in one of the released versions, or if there is a workaround (chkstk?) or a bug report online? Thanks!

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.......

Hi @ll, compiler-rt implements (for example) the MSVC (really Windows) specific routines compiler-rt/lib/builtins/i386/chkstk.S and compiler-rt/lib/builtins/x86_64/chkstk.S as __chkstk_ms() See <http://msdn.microsoft.com/en-us/library/ms648426.aspx> Is there any special reason why compiler-rt doesn't implement other MSVC specific functions (alias builtins or "compiler

Using the LLVM C++ API, if I want to create an array via an Alloca instruction like: Value *a = ir_builder.CreateAlloca( my_type, my_size ); and then I want to initialize each element of the array with values computed elsewhere like: for ( vector<Value*>::const_iterator i = v.begin(); i != v.end(); ++i ) { builder.CreateStore( *i, a ); // How do I increment 'a' to point to

This is pretty ugly, but the names of this functions differs

Hi, I've been writing some optimization passes for LLVM and had good luck with the simple stuff, but I am running into all kinds of trouble trying to make copies of variables within a BasicBlock as part of a LoopPass I am trying to make copies of the variables that are in scope in the loop body like so: //Remove the existing terminator

Hi Thanks for the info, it led to the source of the error I was having. I was using llvm-gcc binaries (built with mingw I guess) to compile a .c file that is my language runtime, llvm-link'ing that with my frontend's .ll, and using an vcpp-built lli to run the resulting bytecode. This caused the special case in X86RegisterInfo::emitPrologue for "main" to try to align the stack

Hi Everyone, I'm quite new to LLVM and I want to update value of global variable in LLVM IR. I created new global variable in ModulePass: bool runOnModule(llvm::Module &M) { IRBuilder<> Builder(M.getContext()); Instruction *I = &*inst_begin(M.getFunction("main")); Builder.SetInsertPoint(I); M.getOrInsertGlobal("globalKey",

The alloca hook is in lib\System\Win32\DynamicLibrary.inc all the way at the bottom. You'll see a __MING32__ #ifdef around the definition. You just have to implement those methods and it'll work just fine.

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*>

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

Hello all, I would like to create a new StoreInst into a basic block. I found that I could use methods like ConstantInt::get() to provide the Value* for the first argument of the constructor of the StoreInst, but I don't know how to provide the second one. For example, if I would to do x = 1, I would like to create the "Value" object of "x" for the second argument. I

To create a stack based (local) 64 bit integer in LLVM IR, I used: Value *var = builder.CreateAlloca(Type::getInt64Ty(Ctx)); I wish to pass this variable to a function "void foo(unsigned long)". I created the signature of function foo() as follows: Constant *func = M->getOrInsertFunction("foo", Type::getVoidTy(Ctx),Type::getInt64Ty(Ctx), NULL); To pass the newly created

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. Garrison On Jan

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
