Basically, this is to get rid of static c'tor/d'tors scattered all over the source tree. (You get them whenever you #include <iostream>.) A smart compiler should be able to remove all of the empty functions because they don't have any side-effects. -bw _______________________________________________ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits
