Machine Value Type.
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
The instances of the Type class are immutable: once they are created, they are never changed.
Definition: Type.h:45
bool isArrayTy() const
True if this is an instance of ArrayType.
Definition: Type.h:252
bool isPointerTy() const
True if this is an instance of PointerType.
Definition: Type.h:255
Type * getArrayElementType() const
Definition: Type.h:404
unsigned getPointerAddressSpace() const
Get the address space of this pointer or pointer vector type.
bool isWebAssemblyExternrefType(const Type *Ty)
Return true if this is a WebAssembly Externref Type.
bool isWebAssemblyFuncrefType(const Type *Ty)
Return true if this is a WebAssembly Funcref Type.
wasm::ValType toValType(MVT Type)
bool isWebAssemblyReferenceType(const Type *Ty)
Return true if this is a WebAssembly Reference Type.
bool isWebAssemblyTableType(const Type *Ty)
Return true if the table represents a WebAssembly table type.
void wasmSymbolSetType(MCSymbolWasm *Sym, const Type *GlobalVT, const ArrayRef< MVT > &VTs)
Sets a Wasm Symbol Type.
