alexlamsl	05a9c02b75	optimise binary operands with evaluate() ... - remove call to evaluate() in is_constant() and let nested optimize() does its job instead - reject RegExp in is_constant() and remove special case logic under collapse_vars - operands to conditionals optimisation are now always evaluate()-ed - throw error in constant_value() instead of returning undefined to catch possible bugs, similar to make_node_from_constant() - optimise binary boolean operators under `evaluate` instead of `conditionals`	2017-01-20 00:08:31 +08:00

Richard van Velzen	27eedbc302	Never produce -0 when evaluating expressions (like -"") ... Fix for #1085. The major case was already there, but more expressions can result in -0.	2016-05-17 22:34:38 +02:00
