The GCC community has talked about link-time optimization for some time. In addition to results with other compilers, Geoff Keating's work on inter-module optimization has demonstrated the potential for improved code-generation from applying optimizations across translation units.

One thing not mentioned here is how are you going to repesent different eh personality functions between languages, because currently we cannot even do different ones in the same compiling at all.

This is very important when compiling some C++ and Java code together. Or even Objective-C and C++.

Thanks, Andrew Pinski
