611 | // Some commentary on balanced locking: | ||||||||
612 | // | ||||||||
613 | // fast_lock and fast_unlock are emitted only for provably balanced lock sites. | ||||||||
614 | // Methods that don't have provably balanced locking are forced to run in the | ||||||||
615 | // interpreter - such methods won't be compiled to use fast_lock and fast_unlock. | ||||||||
616 | // The interpreter provides two properties: | ||||||||
617 | // I1: At return-time the interpreter automatically and quietly unlocks any | ||||||||
618 | // objects acquired the current activation (frame). Recall that the | ||||||||
619 | // interpreter maintains an on-stack list of locks currently held by | ||||||||
620 | // a frame. | ||||||||
621 | // I2: If a method attempts to unlock an object that is not held by the | ||||||||
622 | // the frame the interpreter throws IMSX. | ||||||||
623 | // | ||||||||
624 | // Lets say A(), which has provably balanced locking, acquires O and then calls B(). | ||||||||
625 | // B() doesn't have provably balanced locking so it runs in the interpreter. | ||||||||
626 | // Control returns to A() and A() unlocks O. By I1 and I2, above, we know that O | ||||||||
627 | // is still locked by A(). | ||||||||
628 | // | ||||||||
629 | // The only other source of unbalanced locking would be JNI. The "Java Native Interface: | ||||||||
630 | // Programmer's Guide and Specification" claims that an object locked by jni_monitorenter | ||||||||
631 | // should not be unlocked by "normal" java-level locking and vice-versa. The specification | ||||||||
632 | // doesn't specify what will occur if a program engages in such mixed-mode locking, however. | ||||||||
633 | // Arguably given that the spec legislates the JNI case as undefined our implementation | ||||||||
634 | // could reasonably *avoid* checking owner in fast_unlock(). | ||||||||
635 | // In the interest of performance we elide m->Owner==Self check in unlock. | ||||||||
636 | // A perfectly viable alternative is to elide the owner check except when | ||||||||
637 | // Xcheck:jni is enabled. | ||||||||
