Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

I try to build llvm-gcc-4.2-2.6.source before build and install llvm-2.6, the configure is shown bellow ../llvm-gcc-4.2/configure --prefix=/home/ts/program/ --program-prefix=llvm- --enable-llvm=/home/ts/llvm/llvm-2.6 --enable-languages=c,c++ where, it is the path where llvm-2.6 source is stored, -enable-llvm=/home/ts/llvm/llvm-2.6 the "make" gave error message as bellow:

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

Thank you for reply, I have tried building llvm-2.6 first in place, and configure llvm-gcc-4.2 with --enable-llvm=/path\to\llvm-2.6/, but, still the same problerm, and there's no files missed reported in the error message, such as "lvm/System/DataTypes.h", in the file system including /usr/include and ~/llvm/llvm-2.6/include/. May these files should be generated during llvm-2.6

Hi Everyone, I am trying to construct the print statement : printf("value:%d\n", value); This is my llvm code. It is seg faulting at builder.CreateGlobalStringPtr(str,""). Thanks. George vector<const Type *> params; params.push_back(Type::getInt8PtrTy(M.getContext())); FunctionType *fType = FunctionType::get(Type::getInt32Ty(M.getContext()), params, true); Constant

Hi, I created a global char array, char buffer[1024]. I want to call a function to append the string information to the buffer repeatedly. For example, I need to implement the following code, where length, a, b, c, are global variables. int length = 0; length += sprintf(buffer+length, "str%d", a); length += sprintf(buffer+length, "str%c", b); length += sprintf(buffer+length,

I'm a bit confused. For the Type did you mean something like: ArrayType *type = ArrayType::get(Type::getInt8PtrTy(M.getContext()), 4); This does not work, it gives me ""Wrong type in array element initializer" at runtime. Also it doesn't look like ConstantExpr inherits ConstantArray, so I'm not sure how I could use this instead. Thanks On Thu, Oct 20, 2011 at

Hi, I have a pass that creates a GlobalVariable, when I ran it get the following error: Global is external, but doesn't have external or weak linkage! i8** @myvar This is how I create the GlobalVariable: ------------------------------------------------ new llvm::GlobalVariable(*M, IRB.getInt8PtrTy(), false, llvm::GlobalValue::CommonLinkage, nullptr, "myvar", NULL,

Hi, I am writing an alias profiler using the points-to relation. For this I'm inserting a function call of external function with the following type profile(int,int,int,void*,void*,...) I'm trying to pass the dereferenced pointer's memory address and the address of the location who are in alias set of the pointer. For this i'm using BitCastInst BitCastInst *init1= new

Alexandra, I'm not sure what you mean by "replace", but I have code that does this to insert prefetches: Type *I8Ptr = Type::getInt8PtrTy((*I)->getContext(), PtrAddrSpace); Value *PrefPtrValue = ... IRBuilder<> Builder(MemI); Module *M = (*I)->getParent()->getParent(); Type *I32 = Type::getInt32Ty((*I)->getContext()); Value

Hi, I was wondering if there are any known issues with DwarfEHPrepare::InsertUnwindResumeCalls when using JIT? It appears that the block of code below in this function doesn't correctly handle the case where the rewind function is removed from the module by some other pass (when its unused for instance), and multiple functions are JITed. The RewindFunction variable will get set once, then

Hello, Can anyone please guide me how can I replace a load instruction with a prefetch. I was looking at the intrinsic creation methods of the IRBuilder, but I can only find functions corresponding to memset, memcpy and memmove intrinsics, not for prefetching. Also, I target x86-64 architectures. Is it sufficient to insert a call to the intrinsic in the LLVM IR to have the corresponding prefetch

I have created the function prototype with the following code: const uintmax_t methodNameSize = 1024; const char methodNameTemplate[] = "llvm.memcpy.p0i%llu.p0i%llu.i%llu"; char methodName[methodNameSize]; // Create the methodName. memset(methodName, 0, methodNameSize); sprintf(methodName, methodNameTemplate, dstSize, srcSize, lengthSize); // Search for the

>The type you pass to GlobalVariable's constructor for that variable should be "[10 x %struct.dlist]" because that's what you want storage for. Then the GlobalVariable itself will be a Constant of type "[10 x %struct.dlist]*". Yes, I verified that this is the case. I enabled assertions and the error seems to occur while creating GlobalVariable for both struct dhash
