Abstract: A method of reducing interference among applications co-located in a process when using dynamic libraries is disclosed. For each dynamic library, multiple instances of the dynamic library are loaded in the same operating system process (or process), whereas each instance of the dynamic library corresponds to one of the multiple applications co-located in the same process. In particular, the text segments (or read-only segments) of the instances of the dynamic library are mapped to the same physical memory pages, leading to a low memory footprint. Moreover, within the process, a co-located application's access to a dynamic library is directed to the instance (of the dynamic library) associated with the accessing application, reducing interference among applications co-located in the same process.

Abstract: A system, method and computer program product for compiling and linking a source file and to generate a symbol table associating a global symbol with a register referenced in the source file. The symbol table enables a linker to initialize the global registers using a relocation entry which holds an initializer. The compiler also generates an object file from the source file. The object file includes the global symbol information. A linker links the object file potentially with at least one other object file or shared library to thereby generate an executable file or shared library. The linker uses the global symbol information contained in the object file to initialize the global registers and to perform relocation operations.
