I would like to dump the vtable’s or record’s layout therefore I download the binary of Clang 3.7 for Linux from official site. But I got nothing with:
$ clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04/bin/clang++ -cc1 -fdump-vtable-layouts vtable.cpp
$ clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04/bin/clang++ -cc1 -fdump-record-layouts vtable.cpp
I am wondering how to dump vtable’s or record’s layout? Is there anything wrong with my instructions?
