[cfe-users] How to dump the vtable's or record's layout?

[don hinton via cfe-users]

btw, you might prefer to use -Xclang instead of using -cc1 directly, e.g,

clang++ -Xclang -fdump-record-layouts vtable.cpp

This way, you don't need to worry about passing additional parameters to
-cc1, and you get nice colors if you have a color terminal.
