The at least once evaluation seems ok that it gives more chance to eliminate subexpression for conditional branches. But as mentioned, the main overhead is, it intoduces more functions during code generation. I wonder Is there some number of performance to confirm we are fine even if a lot of common subexpressions are finally evaluated only once ? -- This is an automated message from the Apache Git Service.
