| canCombine | | public int canCombine(CombineableOperator combOp)(Code) | | Checks if the given Expression (which must be a CombineableOperator)
can be combined into this expression.
Parameters:
e - The store expression, must be of type void. 1, if it can, 0, if no match was found and -1, if aconflict was found. You may wish to check for >0.
exception:
ClassCastException - , if e.getOperator is not a CombineableOperator. |
| combine | | public Expression combine(CombineableOperator comb)(Code) | | Combines the given Expression (which should be a StoreInstruction)
into this expression. You must only call this if
canCombine returns the value 1.
Parameters:
e - The store expression. The combined expression.
exception:
ClassCastException - , if e.getOperator is not a CombineableOperator. |
| containsConflictingLoad | | public boolean containsConflictingLoad(MatchableOperator op)(Code) | | Checks if this expression contains a conflicting load, that
matches the given CombineableOperator. The sub expressions are
not checked.
Parameters:
op - The combineable operator. if this expression contains a matching load. |
| containsMatchingLoad | | public boolean containsMatchingLoad(CombineableOperator comb)(Code) | | Checks if this expression contains a matching load, that matches the
given Expression.
Parameters:
comb - The store expression. true, iff this expression contains a matching load.
exception:
ClassCastException - , if e.getOperator is not a CombineableOperator. |
| getFreeOperandCount | | public int getFreeOperandCount()(Code) | | |
| getOperatorIndex | | public int getOperatorIndex()(Code) | | |
| hasSideEffects | | public boolean hasSideEffects(Expression expr)(Code) | | Checks if the value of the given expression can change, due to
side effects in this expression. If this returns false, the
expression can safely be moved behind the current expresion.
Parameters:
expr - the expression that should not change. |
