On AIX and other platforms without weak symbol support, templates need to be instantiated explicitly and symbols for static members of templates will not be generated. + +@item +On AIX, GCC scans object files and library archives for static +constructors and destructors when linking an application before the +linker prunes unreferenced symbols. This is necessary to prevent the +AIX linker from mistakenly assuming that static constructor or +destructor are unused and removing them before the scanning can occur. +All static constructors and destructors found will be referenced even +though the modules in which they occur may not be used by the program. +This may lead to increased executable size and unexpected dependencies +on external symbols. @end itemize @node C++ Misunderstandings |
