Ok, now it's arising another problem. IR code that I obtain is the following: i8* bitcast ([5 x i8] c"hello\00" to i8*) generated from instructions: ConstantExpr::getBitCast (ConstantDataArray::getString (getGlobalContext (), "hello"), PointerType::get (Type::getInt8Ty (getGlobalContext ()), 0)) but the LLC tool says: invalid cast opcode for cast from '[5 x i8]' to 'i8*'.

...r, this code from the verifier broke the Ada front-end build: const Module* M = CI.getParent()->getParent()->getParent(); Constant *MallocFunc = M->getFunction("malloc"); if (CI.getOperand(0) == MallocFunc) { const PointerType *PTy = PointerType::getUnqual(Type::getInt8Ty(CI.getParent()->getContext())); Assert1(CI.getType() == PTy, "Malloc call must return i8*", &CI); } I think it is completely wrong for the verifier to be checking anything about calls to functions that happen to be called "malloc". What if I have my own runtime...

You need to #include "llvm/DerivedTypes.h" instead. But that's not your bug. Don't allocate GlobalVariable val on the stack. You need to 'new' it, ala. 'Glo...

I'm encountering a few problems in my migration that I haven't yet figured out. `getOrInsertFunction` is generating a SEGFAULT at FunctionType::isValidArgumentType(llvm::Type*).  I'm calling it as:     generic_ptr_ = llvm::PointerType::get( llvm::Type::getInt8Ty(context), 0 );     f_natural_int = llvm::IntegerType::get(context, 64);     module->getOrInsertFunction(         "count_malloc", generic_ptr, f_natural_int, (llvm::Type*)0 ); It appears there is no more Reloc::Default or CodeModel::Default, but the docs on those fields indicate there...

...could declare in a function that would then inquire pointer size from TargetData like: FunctionType *geti8LongLong() { const PointerType *LongTy = Type::getIntNPtrTy(Context, TD.getPointerSizeInBits()); std::vector<const Type*> Params = { LongTy, LongTy }; const Type *ResultTy = Type::getInt8Ty(Context); return FunctionType::get(ResultTy, ArgTys, 0); } and then just use the return from geti8LongLong() as the function type when you declare the function. Or you can abstract out away the LongTy and use it in general. -eric
