```
static IFrame create(org.objectweb.asm.commons.AnalyzerAdapter analyzer,
                     int popCount)
```
    Create a IFrame instance based on the given analyzer.
    
    Parameters:
    
    analyzer - analyzer instance or null
    
    popCount - number of items to remove from the operand stack
    
    Returns:
    
    IFrame instance. In case the analyzer is null or does not contain stackmap information a "NOP" IFrame is returned.

```
    Reduce double word types into a single slot as required MethodVisitor.visitFrame(int, int, Object[], int, Object[]) method.
  - accept
