URL: https://github.com/llvm/llvm-project/commit/023361f8ef6aa47d10cd839515c58322890367c3 DIFF: https://github.com/llvm/llvm-project/commit/023361f8ef6aa47d10cd839515c58322890367c3.diff LOG: [lldb][AArch64][Linux][NFC] Move RegisterSetType enum into header (#207145) I will be using this later to replace all the register specific functions this class has (WriteSVE/ReadSVE and so on) with single functions that use RegisterSetType to decide what to do. While I'm here, I've made some sizeof and casts use RegisterSetType in case the underlying type changes later.
