Constructor Details

InstructHash

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 Details

getBlock

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
