1. RegisterClass::getSize() is split into two functions: - TargetRegisterInfo::getRegSizeInBits(const TargetRegisterClass &RC) const; - TargetRegisterInfo::getSpillSize(const TargetRegisterClass &RC) const; 2. RegisterClass::getAlignment() is replaced by: - TargetRegisterInfo::getSpillAlignment(const TargetRegisterClass &RC) const; This will allow making those values depend on subtarget features in the future.
