It was like that until Aug 18th. A commit back then turned the fast macro back into a slow function again and added a division. With that kind of setup, the compiler has no chance to reduce and optimize the target code. By using emalloc+memset, we get compile-time reduction (no multiplication at run-time) and inlining for free. - Sascha -- PHP CVS Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
