LLVMContextImpl *const pImpl
Definition: LLVMContext.h:69
The instances of the Type class are immutable: once they are created, they are never changed.
Definition: Type.h:45
bool isLabelTy() const
Return true if this is 'label'.
Definition: Type.h:213
unsigned NumContainedTys
Keeps track of how many Type*'s there are in the ContainedTys list.
Definition: Type.h:107
LLVMContext & getContext() const
Return the LLVMContext in which this type was uniqued.
Definition: Type.h:129
Type *const * ContainedTys
A pointer to the array of Types contained by this Type.
Definition: Type.h:114
void setSubclassData(unsigned val)
Definition: Type.h:100
bool isX86_AMXTy() const
Return true if this is X86 AMX.
Definition: Type.h:204
bool isTokenTy() const
Return true if this is 'token'.
Definition: Type.h:219
bool isVoidTy() const
Return true if this is 'void'.
Definition: Type.h:140
bool isMetadataTy() const
Return true if this is 'metadata'.
Definition: Type.h:216
A few GPU targets, such as DXIL and SPIR-V, have typed pointers.
static bool isValidElementType(Type *ElemTy)
Return true if the specified type is valid as a element type.
static TypedPointerType * get(Type *ElementType, unsigned AddressSpace)
This constructs a pointer to an object of the specified type in a numbered address space.
This is an optimization pass for GlobalISel generic memory operations.
