public InstructHash(Instruction inst,
                    Block bl,
                    int ind)
```
    Build an (unmatched) Instruction, associating it with its position in the basic block
    
    Parameters:
    
    inst - is the underlying instruction
    
    bl - is the basic-block
    
    ind - is the index within the block
- Method Detail

```
public Block getBlock()
```
    Returns:
    
    the containing basic block
  - allUnknown
```
public boolean allUnknown(int length)
```
    If the -length- instructions, starting with this, are all unmatched, return true;
    
    Parameters:
    
    length - is number of instructions to check
    
    Returns:
    
    true if all checked instructions are unmatched
  - clearSort
```
protected void clearSort()
```
    Clear out structures associated with the main sort
  - clearNGrams
```
protected void clearNGrams(int sz)
```
    Clear out the n-gram array to an uninitialized list
    
    Parameters:
    
    sz - is the size of the uninitialized list
