摘要： Methods and apparatus to provide transactional memory execution in out-of-order processors are described. In one embodiment, a stored value corresponds to the number of transactional memory access requests that are uncommitted. The stored value may be used to provide nested recovery in case of an error, fault, etc. in accordance with a described embodiment.

摘要： An apparatus and method is described herein for providing robust speculative code section abort control mechanisms. Hardware is able to track speculative code region abort events, conditions, and/or scenarios, such as an explicit abort instruction, a data conflict, a speculative timer expiration, a disallowed instruction attribute or type, etc. And hardware, firmware, software, or a combination thereof makes an abort determination based on the tracked abort events. As an example, hardware may make an initial abort determination based on one or more predefined events or choose to pass the event information up to a firmware or software handler to make such an abort determination. Upon determining an abort of a speculative code region is to be performed, hardware, firmware, software, or a combination thereof performs the abort, which may include following a fallback path specified by hardware or software. And to enable testing of such a fallback path, in one implementation, hardware provides software a mechanism to always abort speculative code regions.

摘要： Example methods and apparatus to manage object locks are disclosed. A disclosed example method includes receiving an object lock request from a processor, the lock request associated with object lock code to lock an object, and generating object lock-bypass code based on a type of the processor, the object lock-bypass code to execute in a managed runtime in response to receiving the object lock request. The example method also includes identifying a type of instruction set architecture (ISA) associated with the processor, invoking a checkpoint instruction for the processor based on the identified ISA, suspending the object lock code from executing and executing target code when the object is uncontended, and allowing the object lock code to execute when the object is contended.

摘要： An apparatus and method is described herein for providing speculative escape instructions. Specifically, an explicit non-transactional load operation is described herein. During execution of a speculative code region (e.g. a transaction or critical section) loads are normally tracked in a read set. However, a programmer or compiler may utilize the explicit non-transactional read to load from a memory address into a destination register, while not adding the read/load to the transactional read set. Similarly, a non-transactional store is also provided. Here, a transactional store is performed and not added to a write set during speculative code execution. And the store may be immediately globally visible and/or persistent (even after an abort of the speculative code region). In other words, speculative escape operations are provided to ‘escape’ a speculative code region to perform non-transactional memory accesses without causing the speculative code region to abort or fail.
摘要翻译： 这里描述了一种用于提供推测逃逸指令的装置和方法。 具体地，本文描述了显式的非事务性加载操作。 在推测性代码区域（例如交易或关键部分）的执行期间，通常在读取集合中跟踪负载。 然而，程序员或编译器可以利用显式的非事务性读取从存储器地址加载到目标寄存器中，而不将读取/加载添加到事务读取集合。 同样，也提供非事务存储。 这里，在推测性代码执行期间执行事务存储并且不添加到写入集合。 并且商店可能立即全局可见和/或持久（即使在推测性代码区域中止之后）。 换句话说，提供推测性逃避操作以“逃逸”推测性代码区域以执行非事务性存储器访问，而不会导致推测性代码区域中止或失败。
