- Type for realm objects is introduced (ecma_global_object_t) - Realm reference is added to built-in objects and ECMAScript functions - Resolving built-ins, global environments, and scopes require realm object - Unnecessary global object accesses are removed from the code Missing: external functions and static snapshot functions have no realm reference JerryScript-DCO-1.0-Signed-off-by: Zoltan Herczeg zherczeg.u-szeged@partner.samsung.com
