static unsigned getOpcode

(

const Value *

V

)

[static]

getOpcode - If this is an Instruction or a ConstantExpr, return the opcode value. Otherwise return UserOp1.

Definition at line 101 of file ScheduleDAGInstrs.cpp.

References UserOp1.

static const Value* getUnderlyingObject

(

const Value *

V

)

[static]

getUnderlyingObject - This is a wrapper around Value::getUnderlyingObject and adds support for basic ptrtoint+arithmetic+inttoptr sequences.

Definition at line 139 of file ScheduleDAGInstrs.cpp.

References getOpcode(), llvm::Value::getType(), llvm::Value::getUnderlyingObject(), and getUnderlyingObjectFromInt().

Referenced by getUnderlyingObjectForInstr().

static const Value* getUnderlyingObjectForInstr

(

const MachineInstr *

MI

)

[static]

getUnderlyingObjectForInstr - If this machine instr has memory reference information and it can be tracked to a normal reference to a known object, return the Value for that object. Otherwise return null.

Definition at line 158 of file ScheduleDAGInstrs.cpp.

References getUnderlyingObject(), llvm::MachineInstr::hasOneMemOperand(), llvm::isIdentifiedObject(), llvm::MachineInstr::memoperands_begin(), and V.

static const Value* getUnderlyingObjectFromInt

(

const Value *

V

)

[static]

getUnderlyingObjectFromInt - This is the function that does the work of looking through basic ptrtoint+arithmetic+inttoptr sequences.
