Nikita Popov	8f623fb241	Use closures instead of methods for semantic actions ... The dispatch using $this->{'reduceRule' . $rule}() is very expensive because it involves * One allocation when converting $rule to a string * Another allocation when concatenating the two strings * Lowercasing during the method call * Various uncached method checks, e.g. visibility. Using an array of closures for semantic action dispatch is significantly more efficient.	2017-02-05 11:58:45 +01:00
Nikita Popov	3bbf8d8f7a	Use local var for $stackPos ... We're accessing $this->stackPos a lot, and property accesses are much more expensive than local variable acesses. Its cheaper to use a local var and pass it as an argument to semantic actions.	2017-02-05 11:57:21 +01:00
Nikita Popov	bc21514ecf	Move token constants into separate class ... As these are shared between Php5 and Php7 parsers they should be in some common place, otherwise we'd have to always reference either one or the other.	2015-06-13 18:39:55 +02:00
