static SDValue getAL ( SelectionDAG *  CurDAG )

inlinestatic

getAL - Returns a ARMCC::AL immediate node.

static bool isInt32Immediate ( SDNode *  N, unsigned &  Imm  )

static

isInt32Immediate - This method tests to see if the node is a 32-bit constant operand. If so Imm will receive the 32-bit value.

static bool isScaledConstantInRange ( SDValue  Node, int  Scale, int  RangeMin, int  RangeMax, int &  ScaledConstant  )

static

Check whether a particular node is a constant value representable as (N * Scale) where (N in [RangeMin, RangeMax).

Parameters

ScaledConstant

[out] - On success, the pre-scaled constant value.
