  9. Bytecode compression with bzip2 has been implemented. All bytecode files + generated by LLVM will now be compressed by default. Compression can be + disabled with the -disable-compression option to the tools that can + generate bytecode files. +
    10. +
  10. A generic compiler driver and + an associated generic linker have + been implemented. The compiler driver is generic because it can be configured + to pre-process, translate, optimize, assemble, and link code from any source + language. This aids compiler writers because all that is needed is a + source-to-bytecode or source-to-assembly translator and a configuration file. + The linker is generic because it allows dynamically loadable optimization + modules to be executed for link-time optimization. Language specific + link-time optimization modules can be created and executed automatically. +
    11. +
  11. The dependent libraries + feature has been implemented. This allows front end compilers to indicate in + the bytecode which libraries the bytecode needs to be linked with. Both the + C/C++ front end and Stacker support generating the required libraries. The + Linker now supports using this information to ensure required libaries are + linked into the module. This minimizes the need to use the -l option + when using llvmc +
