[RFC PATCH 0/2] check for identical exprs on LHS and RHS of '&&'
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi, I've started working on a new check for sparse to pick up a common error -- identical expressions appearing on both sides of some binary operators. This initially supports '&&', and incompletely -- but the plan is to check instances of '!=', '==' and '||' the same way. The check relies on recursively walking the ->left and ->right expressions, looking for differences. The implementation is a little verbose, but can be shared between all the operators. What I'd like to know is: * Do people consider this a worthwhile check to make? * Am I "doing it right" with the expression walking? * Are there other cases which people would be interested in?
