Abstract
A dynamic linking system can be designed to dynamically resolve symbol references of pages associated with executable code as the pages are paged into virtual memory. The operating system can include a dynamic linker that uses metadata in the pages to determine symbol references that reference other code or values. Other code can include code in shared libraries. The dynamic linker can generate a data structure containing the symbol references in a small and dense format. The dynamic linker can send the data structure and other relevant data to the kernel once the symbol references have been identified. The kernel can perform the functions related to resolving the symbol references. For example, the kernel can resolve the symbol by determining a pointer value for the symbol, wherein the pointer value can be used to point to code or values. The kernel can resolve the symbol references and store the data structure, which contains the resolved symbol references.
