◆ accumulateConstantOffset() [1/2]

bool llvm::GEPOperator::accumulateConstantOffset ( const DataLayout DL,
APInt Offset,
function_ref< bool(Value &, APInt &)>  ExternalAnalysis = nullptr 
) const

Accumulate the constant address offset of this GEP if possible.

This routine accepts an APInt into which it will try to accumulate the constant offset of this GEP.

If ExternalAnalysis is provided it will be used to calculate a offset when a operand of GEP is not constant. For example, for a value ExternalAnalysis might try to calculate a lower bound. If ExternalAnalysis is successful, it should return true.

If the ExternalAnalysis returns false or the value returned by ExternalAnalysis results in a overflow/underflow, this routine returns false and the value of the offset APInt is undefined (it is not preserved!).

The APInt passed into this routine must be at exactly as wide as the IntPtr type for the address space of the base GEP pointer.
