Constructor Details

AbstractCStatementOptimizer

public AbstractCStatementOptimizer()

Create a statement optimizer.

Method Details

optimizeBlock

protected int optimizeBlock(ICBlock b)

The default implementation iterates over each statement of the block and calls optimizeStatement(ICStatement). Most sub-classes should not override this method.

Specified by:

optimizeBlock in class AbstractCBlockOptimizer

Parameters:

b - CBlock

Returns:

the number of optimizations done

optimizeStatement

protected abstract ICStatement optimizeStatement(ICStatement stm)

Optimize a statement.

Parameters:

stm - the statement to optimize

Returns:

a non-statement if it was optimized; null means the statement was not optimized
