Abstract: A method for recording and profiling information of a plurality of aborted transactions from a plurality of transactions is executed by processor core with a transactional memory, a transaction failure instruction address register (TFIAR), and a transaction failure data address register (TFDAR). The transactional memory stores information of a plurality of transactions executed by the processor core. The processor core retrieves instruction and data address associated with the aborted transaction from TFIAR and TFDAR respectively and stores them into a profiling table. The processor core then generates profiling information based on instruction and data addresses associated with the aborted transaction.

Abstract: A method for lock reservation using cooperative multithreading is provided. The method includes analyzing code containing async points to support cooperative multithreading. The method also includes identifying a class of code as a candidate for reservation via determining locking properties within the code as a function of locations of async points within the code, and generating reserving code that reserves the shared object when code performing the reservation is considered hot code. The method further includes performing runtime monitoring of reservation performance to detect a contention level for the shared object, and removing the reservation when the runtime monitoring determines that a low level of contention exists.

Abstract: This invention provides a process within an optimizing compiler for transforming code to take advantage of update instructions available on some computer architectures. On architectures which implement some form of autoindexing instructions or addressing modes, this process will improve the code generated for looping constructs which manipulate arrays in memory. The process is achieved by selecting memory referencing instructions inside loops for conversion to update forms, modifying those instructions to an update form available on a particular processor, and applying an offset compensation to other memory referencing instructions in the loop so as to enable the program to still address the appropriate locations while using the available autoindexing instructions. The improved compiler and compiler process enables the compiler to convert those program instructions that would otherwise convert to autoindexing instructions not supported by the processor to autoindexing instructions that are supported.

Abstract: A soft rubber seal member is molded in the cavity in the face of the valve core. During the molding process air can escape through the slots or gates in the annular ring in the face of the valve core. When rubber starts coming out the gate, the gates are closed off and the rubber hardens in the gates. The valve is used in combination with a valve housing provided with an entry orifice having a diverging exit section leading to a flat annular surface against which the flat central portion of the soft rubber seal will seat when the valve is closed. This obtains a large seating area and ensures uniform valve opening pressure.
