Function Documentation

static unsigned getBCCForSetCC ( ISD::CondCode CC ) [static]

getBCCForSetCC - Returns the PowerPC condition branch mnemonic corresponding to Condition.

static unsigned getCRIdxForSetCC	(	ISD::CondCode	CC,
		bool &	Inv
	)			`[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.

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.

		uint64_t &	Imm
	)			`[static]`

isInt64Immediate - This method tests to see if the node is a 64-bit constant operand. If so Imm will receive the 64-bit value.

static bool isIntS16Immediate	(	SDNode *	N,
		short &	Imm
	)			`[static]`

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.
