view gen/logger.cpp @ 102:027b8d8b71ec trunk

[svn r106] Turns out the last commit wasn't enough, now the D->LLVM process is even more split up. Basically it tries to do the following in order: Resolve types, Declare symbols, Create constant initializers, Apply initializers, Generate functions bodies. ClassInfo is now has the most useful(biased?) members working. Probably other stuf...
