Hi, I'm working on call/return sequence optimization. As part of this work I'm minimizing the size of call frame (zend_execute_data) and number of read/write operations on call/return.
Could you please take a look into the patch that removes EX(scope) https://gist.github.com/dstogov/5ad50d582346385d587e All phpt tests are passed, but I'm not completely sure about one line - https://gist.github.com/dstogov/5ad50d582346385d587e#file-ex_scope-05-diff-L193 On the other hand I can't imagine what it may break. Matteo, can you please run your test suites with this patch. PS: I'm also going to: - pack EX(num_args) into reserved space of EX(This) - try to get rid of EX(frame_info) - try to merge EX(called_scope) and EX(This). Only one of them matters. - try to replace zval EX(This) with a pointer to zend_object EX(object) Thanks. Dmitry.
