摘要： The present invention provides a method to optimize object code files produced by a compiler for several different types of target processors. The compiler divides the source code to be compiled into several functional modules. Given a specified set of target processors, each functional module is compiled resulting in a target object version for each target processor. Then, for each functional module, a merging process is performed wherein identical target object versions or target object versions with similar contents are merged by deleting the identical or similar versions. After this merging process, a composite object code file is formed containing all of the non-deleted target object versions of the function modules.

摘要： A method for resetting of memory locks in a transactional memory system. The method includes a processor setting at least one new memory lock during execution of a transaction that acquires access to a region of memory. The new memory lock indicates that the transaction and its associated thread have exclusive temporary access to the memory region. The method further includes determining if a first in first out (FIFO) memory lock register is full of memory locks and, in response to the FIFO memory lock register being full, a memory lock is removed from a tail position of the FIFO memory lock register. The removed memory lock is reset to return to a transactional memory state and the new memory lock is added to a head position in the FIFO memory lock register.

摘要： A system and computer program product for resetting of memory locks in a transactional memory system. The system includes a processor setting at least one new memory lock during execution of a transaction that acquires access to a region of memory. The new memory lock indicates that the transaction and its associated thread have exclusive temporary access to the memory region. The system further includes the processor determining if a first in first out (FIFO) memory lock register is full of memory locks and, in response to the FIFO memory lock register being full, a memory lock is removed from a tail position of the FIFO memory lock register. The removed memory lock is reset to return to a transactional memory state and the new memory lock is added to a head position in the FIFO memory lock register.
