Detailed Description

Construction/uniquing key class for LLVM dialect structure storage.

Note that this is a transient helper data structure that is NOT stored. Therefore, it intentionally avoids bit manipulation and type erasure in pointers to make manipulation more straightforward. Not all elements of the key participate in uniquing, but all elements participate in construction.

◆ Key() [2/2]

mlir::LLVM::detail::LLVMStructTypeStorage::Key::Key	(	ArrayRef< Type >	types,
		bool	packed
	)

inline

Constructs a key for a literal struct.

◆ getTypeList()

ArrayRef<Type> mlir::LLVM::detail::LLVMStructTypeStorage::Key::getTypeList ( ) const

◆ hashValue()

llvm::hash_code mlir::LLVM::detail::LLVMStructTypeStorage::Key::hashValue ( ) const

inline

Returns the hash value of the key.

This combines various flags into a single value: the identified flag sets the first bit, and the packedness flag sets the second bit. Opacity bit is only used for construction and does not participate in uniquing.
