Hi all, consider the following function from Core.cpp in LLVM 9.0.0: LLVMValueRef LLVMBuildMalloc(LLVMBuilderRef B, LLVMTypeRef Ty, const char *Name) { Type* ITy = Type::getInt32Ty(unwrap(B)->GetInsertBlock()->getContext()); Constant* AllocSize = ConstantExpr::getSizeOf(unwrap(Ty)); AllocSize = ConstantExpr::getTruncOrBitCast(AllocSize, ITy); Instruction* Malloc = CallInst::CreateMalloc(unwrap(B)->GetInsertBlock(), ITy, u...

In trying to write a C binding for DIBuilder of llvm 3.6.1, I can't see a way to unwrap llvm::DITypeRef, declared in include/llvm/IR/DebugInfo.h. This is a class with one data member, a pointer to Metadata. If I try to make my C type a struct with one pointer, I can't cast it to DITypeRef. If I try to go inside the classes and use the pointer, I can cast, but can't construct...

I''ve noticed that the dsl_dataset_t that points to a given dataset changes during the life time of a ''zfs create'' command. We start out with one dsl_dataset_t* during dmu_objset_create_sync() but by the time we are later mounting the dataset we have a different in memory dsl_dataset_t* referring to the same dataset. This causes me a big issue with per dataset

Hi (Gordon). There appears to be two wrapper functions for DerivedType::refineAbstractTypeTo() in llvm-c (Core.h, Core.cpp): void LLVMRefineAbstractType(LLVMTypeRef AbstractType, LLVMTypeRef ConcreteType){ DerivedType *Ty = unwrap<DerivedType>(AbstractType); Ty->refineAbstractTypeTo(unwrap(ConcreteType)); } void LLVMRefineType(LLVMTypeRef AbstractTy, LLVMTypeRef ConcreteTy) { unwrap<DerivedType>(AbstractTy)->refineAbstractTypeTo(unwrap(ConcreteTy)); } The attached patch removes the first one. Regards...

Here is my python loader plugin which loads plain python scripts as full plugins. There is not much documentation, but I have included a few examples to get you going. triangle - Just a basic plugin which shows a triangle on a button press. This shows using ctypes to pass values from compiz to the python opengl bindings. basiczoom - Zooms in on the screen (basically) inactive - This is a port

Hi, I'm no phone guy but I've been having quite a bit of fun messing with Asterisk. I just unwrapped my new Wildcard TDM400P (TDM40B) which is the new 4 port FXS PCI card. It has 4 RJ45 connectors and I'd like to hookup 4 regular phones which are RJ11. If I crip RJ45 connectors to the phone cords do I simple use the center two pins (pins 4 and 5)? Thanks, Randy Smith Tiger Mountain Te...
