// Function GetConstantValueAsUnsignedInt
// Function GetConstantValueAsSignedInt
//
// Convenience functions to get the value of an integer constant, for an
// appropriate integer or non-integer type that can be held in a signed
// or unsigned integer respectively. The type of the argument must be
// the following:
// Signed or unsigned integer
// Boolean
// Pointer
//
// isValidConstant is set to true if a valid constant was found.
//---------------------------------------------------------------------------
uint64_t GetConstantValueAsUnsignedInt (const Value *V,
bool &isValidConstant);
int64_t GetConstantValueAsSignedInt (const Value *V,
bool &isValidConstant);
//---------------------------------------------------------------------------
// Function: GetMemInstArgs
//
// Purpose:
// Get the pointer value and the index vector for a memory operation
// (GetElementPtr, Load, or Store). If all indices of the given memory
// operation are constant, fold in constant indices in a chain of
// preceding GetElementPtr instructions (if any), and return the
// pointer value of the first instruction in the chain.
// All folded instructions are marked so no code is generated for them.
//
// Return values:
// Returns the pointer Value to use.
// Returns the resulting IndexVector in idxVec.
// Returns true/false in allConstantIndices if all indices are/aren't const.
//---------------------------------------------------------------------------

std::vector<Value*>& idxVec,
