static unsigned getCRIdxForSetCC	(	ISD::CondCode	CC,
		bool &	Invert,
		int &	Other
	)			[static]

getCRIdxForSetCC - Return the index of the condition register field associated with the SetCC condition, and whether or not the field is treated as inverted. That is, lt = 0; ge = 0 inverted.

If this returns with Other != -1, then the returned comparison is an or of two simpler comparisons. In this case, Invert is guaranteed to be false.

isIntS16Immediate - This method tests to see if the node is either a 32-bit or 64-bit immediate, and if the value can be accurately represented as a sign extension from a 16-bit value. If so, this returns true and the immediate.
