Previously the dumping of class definitions was very primitive, and it made it hard to do more than the most trivial of output formats when dumping. As such, we would only dump one line for each field, and then dump non-layout items like nested types and enums. With this patch, we do a complete analysis of the object hierarchy including aggregate types, bases, virtual bases, vftable analysis, etc. The only immediately visible effects of this are that a) we can now dump a line for the vfptr where before we would treat that as padding, and b) we now don't treat virtual bases that come at the end of a class as padding since we have a more detailed analysis of the class's storage usage. In subsequent patches, we should be able to use this analysis to display a complete graphical view of a class's layout including recursing arbitrarily deep into an object's base class / aggregate member hierarchy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@300133 91177308-0d34-0410-b5e6-96231b3b80d8
