# LxValue The following is copied from llvm-c/Core.h

The bulk of LLVM's object model consists of values, which comprise a very rich type hierarchy.

LLVMValueRef essentially represents llvm::Value. There is a rich hierarchy of classes within this type. Depending on the instance obtained, not all APIs are available.

Callers can determine the type of an LLVMValueRef by calling the LLVMIsA* family of functions (e.g. LLVMIsAArgument()). These functions are defined by a macro, so it isn't obvious which are available by looking at the Doxygen source code. Instead, look at the source definition of LLVM_FOR_EACH_VALUE_SUBCLASS and note the list of value names given. These value names also correspond to classes in the llvm::Value hierarchy.
