摘要： A method for loading shared libraries. The method includes receiving an indication of a requirement to load the shared library into the virtual memory and determining that the shared library is a candidate for using shared large pages. Further, the method includes, in response to the determination, storing a text section of the shared library in a shared large page of the virtual memory and storing a data section of the shared library in a page of the virtual memory, where the virtual memory is mapped to a physical memory of the computer, where, within an address space of the virtual memory, a starting address of the text section of the shared library is separated from a starting address of the data section of the shared library by a predefined distance, and where the predefined distance is larger than a size of the large page.

摘要： A method and apparatus for providing versioning information for a plurality of software objects. When an object is compiled and linked, at build time, the link-editor creates a version definition section and a version symbol section in the object that specify the global symbols defined in various versions of the object. The object can be a shared object, a relocatable object, or a dynamic executable object. When an application software program is linked with the versioned object, at build time, the linker-editor creates a version dependency section in the resulting dynamic executable object that specifies which version of the object is required for execution of the software application program. At runtime, the runtime-linker determines whether all required versions of the object are present before the program is executed. The invention allows the definition of "weak" versions that do not contain new global symbols. The invention also allows the explicit specification of the version of an object to which the software application program should be linked.
