Methods
¶ConstantPointerNull(
const llvm::ConstantPointerNull&)
ConstantPointerNull(
const llvm::ConstantPointerNull&)Declared at: llvm/include/llvm/IR/Constants.h:548
Parameters
- const llvm::ConstantPointerNull&
¶static bool classof(const llvm::Value* V)
static bool classof(const llvm::Value* V)Description
Methods for support type inquiry through isa, cast, and dyn_cast:
Declared at: llvm/include/llvm/IR/Constants.h:560
Parameters
- const llvm::Value* V
¶static llvm::ConstantPointerNull* get(
llvm::PointerType* T)
static llvm::ConstantPointerNull* get(
llvm::PointerType* T)Description
Static factory methods - Return objects of the specified value
Declared at: llvm/include/llvm/IR/Constants.h:551
Parameters
¶inline llvm::PointerType* getType() const
inline llvm::PointerType* getType() constDescription
Specialize the getType() method to always return an PointerType, which reduces the amount of casting needed in parts of the compiler.
