摘要： Systems and methods for Just-My-Code (JMC) debugging are described. In one aspect, debugging probes are automatically inserted into respective programming constructs representing interesting code. The debugging probes are inserted during computer computer-program compiling operations that generate native code. The native code is then executed as a process. The process includes one or more threads of execution that run-free through uninteresting code during a JMC step operation. A thread of the one or more threads is only halted in the interesting code when an active one of the debugging probes is encountered by the thread while the thread is JMC stepping through the process.

摘要： Various technologies and techniques are disclosed for supporting parallel nested transactions in a transactional memory system. Multiple closed nested transactions are created for a single parent transaction, and the closed nested transactions are executed concurrently as parallel nested transactions. Various techniques are used to ensure effects of the parallel nested transactions are hidden from other transactions outside the parent transaction until the parent transaction commits. For example, versioned write locks are used with parallel nested transactions. When a transactional memory word changes from a write lock to a versioned write lock, an entry is made in a global versioned write lock map to store a pointer to a write log entry that the versioned write lock replaced. When the versioned write lock is encountered during transaction processing, the global versioned write lock map is consulted to translate the versioned write lock to the pointer to the write log entry.

摘要： Various technologies and techniques are disclosed that improve implementation of concurrency control modes in a transactional memory system. A transactional memory word is provided for each piece of data. The transactional memory word includes a version number, a reader indicator, and an exclusive writer indicator. The transactional memory word is analyzed to determine if the particular concurrency control mode is proper. Using the transactional memory word to help with concurrency control allows multiple combinations of operations to be performed against the same memory location simultaneously and/or from different transactions. For example, a pessimistic read operation and an optimistic read operation can be performed against the same memory location.

摘要： The efficient use of type descriptors with frozen objects. A frozen object might actually include several type descriptors, a primary type descriptor that is canonical according to a set of canonicalization rules, and an auxiliary type descriptor that is not identical to the primary type descriptor. The auxiliary type descriptor may be used to access the canonical type descriptor. When performing an operation, if the auxiliary type descriptor can be used to perform the operation, then that auxiliary type descriptor may be used. If the canonical type descriptor is to be used to perform the operation, the auxiliary type descriptor is used to gain access to the canonical primary type descriptor. The primary type descriptor is then used to perform the operation.

摘要： Software transactional memory (STM) primitives are provided that allow the results of prior open calls to be used by subsequent open calls either as-is or through another STM primitive that consumes the results of the previous invocation. The STM primitives are configured to ensure that the address of a shadow copy representing a memory location will not changed across a wide range of operations and thereby enable re-use of the shadow copy.

摘要： The techniques and mechanisms described herein are directed to a method for virtually catching an exception. A debugger receives a notification identifying information about an exception that occurred during execution of an application. The debugger then selectively chooses a location on a call stack where execution of the application resumes after the stack is unwound up to the selected location. The location being between a statement on the stack causing the exception and a handler on the stack. The handler being identified during a search phase for exception processing. The mechanism being operative for both handled exceptions and unhandled exceptions.

摘要： Various technologies and techniques are disclosed for implementing retrying transactions in a transactional memory system. The system allows a transaction to execute a retry operation. The system registers for waits on every read in a read set of the retrying transaction. The retrying transaction waits for notification that something in the read set has changed. A transaction knows if notification is required in one of two ways. If the transactional memory word contained a waiters bit during write lock acquisition, then during release the transactional memory word is looked up in an object waiters map, and waiting transactions are signaled. If a writing transaction finds a global count of waiting transactions to be greater than zero after releasing write locks, a transaction waiters map is used to determine which waiting transactions need to be signaled. In each case, the write lock is released using a normal store operation.

摘要： Various technologies and techniques are disclosed for handling exceptions in sequential statements that are executed in parallel. A transactional memory system is provided with a contention manager. The contention manager is responsible for managing exceptions that occur within statements that were designed to be executed in an original sequential order, and that were transformed into ordered transactions for speculative execution in parallel. The contention manager ensures that any exceptions that are thrown from one or more speculatively executed blocks while the statements are being executed speculatively in parallel are handled in the original sequential order.
