andi Fri Oct 22 17:42:14 2004 EDT Added files: /ZendEngine2 zend_vm_def.h zend_vm_execute.skl zend_vm_gen.php Modified files: /ZendEngine2 Makefile.frag zend_execute.c zend_vm.h Log: - Commit new VM - Old one is tagged as PRE_NEW_VM_GEN_PATCH - Still doing work so more commits to come. Don't complain (yet) :)
