摘要： A minimal rebuild system and process for minimizing rebuilding of a user's programming project analyzes and records dependencies of object code files compiled in a previous build of the project on classes declared in header files. When rebuilding the project, the system detects and records changes made to the classes and header files since the project was last built. The system then determines whether to recompile the object code files from their respective source code files by comparing the recorded dependencies and changes. If an object code file's dependencies do not intersect the changes, recompiling of the object code file can be omitted. The minimal rebuild system utilizes an approximate representation of the dependencies to yield an efficient system while ensuring that the project is correctly rebuilt.

摘要： A method and system for generating code to destroy objects is provided. In a preferred embodiment, a compiler generates a plurality of destructor functions for the class. Each destructor function performs a subset of the destruction process. The compiler generates code to invoke one of the plurality of destructor functions to destroy an object of the class. In a preferred embodiment, destructor functions are generated to destroy an object that is not ultimately derived, to destroy an object that is ultimately derived, to destroy an object that is ultimately derived and to deallocate the object memory, to destroy an array of objects, and to destroy an array of objects and to deallocate the memory of the array.

摘要： Various technologies and techniques are disclosed for providing software accessible metadata on a cache of a central processing unit. A multiprocessor has at least one central processing unit. The central processing unit has a cache with cache lines that are augmented by cache metadata. The cache metadata includes software-controlled metadata identifiers that allow multiple logical processors to share the cache metadata. The metadata identifiers and cache metadata can then be used to accelerate various operations. For example, parallel computations can be accelerated using cache metadata and metadata identifiers. As another example, nested computations can be accelerated using metadata identifiers and cache metadata. As yet another example, transactional memory applications that include parallelism within transactions or that include nested transactions can be also accelerated using cache metadata and metadata identifiers.

摘要： Various technologies and techniques are disclosed for transforming a sequential loop into a parallel loop for use with a transactional memory system. A transactional memory system is provided. A first section of code containing an original sequential loop is transformed into a second section of code containing a parallel loop that uses transactions to preserve an original input to output mapping. For example, the original sequential loop can be transformed into a parallel loop by taking each iteration of the original sequential loop and generating a separate transaction that follows a pre-determined commit order process. At least some of the separate transactions are executed in different threads. When an unhandled exception is detected that occurs in a particular transaction while the parallel loop is executing, state modifications made by the particular transaction and predecessor transactions are committed, and state modifications made by successor transactions are discarded.

摘要： A method and system in an object-oriented environment for determining the offset of a data member of a derived class when the derived class has a virtually inherited base class and the data member is defined in the base class. In a preferred embodiment, the base class has a data structure and a class address. The base class data structure has the data member located at a data member offset from the base class address. The derived class has a data structure and a class address. The derived class data structure includes an occurrence of the base class data structure. The occurrence of the base class data structure is located at a base class offset from the derived class address. In a preferred embodiment, the base class offset is stored at a memory location, a first field and a second field for a pointer to the data member are allocated, the data member offset is stored in the first field, an indicator of the stored base class offset is stored in the second field, the pointer is dereferenced by retrieving the base class offset using the indicator stored in the second field, retrieving the data member offset from the first field, and adding the retrieved base class offset to the retrieved data member offset to give the offset of the data member within the derived data structure.

摘要： Various technologies and techniques are disclosed for providing a hardware accelerated software transactional memory application. The software transactional memory application has access to metadata in a cache of a central processing unit that can be used to improve the operation of the STM system. For example, open read barrier filtering is provided that uses an opened-for-read bit that is contained in the metadata to avoid redundant open read processing. Similarly, redundant read log validation can be avoided using the metadata. For example, upon entering commit processing for a particular transaction, a get-evictions instruction in an instruction set architecture of the central processing unit is invoked. A retry operation can be optimized using the metadata. The particular transaction is aborted at a current point and put to sleep. The corresponding cache line metadata in the metadata are marked appropriately to efficiently detect a write by another CPU.

摘要： Various technologies and techniques are disclosed for transforming a sequential loop into a parallel loop for use with a transactional memory system. Open ended and/or closed ended sequential loops can be transformed to parallel loops. For example, a section of code containing an original sequential loop is analyzed to determine a fixed number of iterations for the original sequential loop. The original sequential loop is transformed into a parallel loop that can generate transactions in an amount up to the fixed number of iterations. As another example, an open ended sequential loop can be transformed into a parallel loop that generates a separate transaction containing a respective work item for each iteration of a speculation pipeline. The parallel loop is then executed using the transactional memory system, with at least some of the separate transactions being executed on different threads.
