The GCC documentation states that, as of GCC 2.7.2, these aren't necessary for proper program behavior. The documentation further discourages their use because they don't suppress unnecessary code duplication. The Panda codebase these days uses "extern template class" instead, which tells the compiler not to perform implicit template expansion because an explicit template expansion is available for linking elsewhere in the program. This is a more compiler-neutral way of achieving the same thing as '#pragma interface', making '#pragma interface' not only redundant, it could also mask problems in the "extern template class" machinery. |
