- for <tt>Release</tt> and <tt>Profile</tt> builds.
+ <li>A generic <a href="http://llvm.cs.uiuc.edu/PR353">compiler driver</a> and
+ an associated <a href="CommandGuide/html/llvm-ld.html">generic linker</a> 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.
+ </li>
+ <li>The <a href="http://llvm.cs.uiuc.edu/PR263">dependent libraries</a>
+ 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 <tt>-l</tt> option
+ when using <a href="CommandGuide/html/llvmc.html"><tt>llvmc</tt></a>
