| const uint32_t * AArch64RegisterInfo::getThisReturnPreservedMask | ( | CallingConv::ID | ) | const |
getThisReturnPreservedMask - Returns a call preserved mask specific to the case that 'returned' is on an i64 first argument if the calling convention is one that can (partially) model this attribute with a preserved mask (i.e. it is a calling convention that uses the same register for the first i64 argument and an i64 return value)
Should return NULL in the case that the calling convention does not have this property

needsFrameBaseReg - Returns true if the instruction's frame index reference would be better served by a base register other than FP or SP. Used by LocalStackFrameAllocation to determine which frame index references it should create new base registers for.
