As per Reid's early response, try adding -emit-llvm-only or -emit-obj.

Hello all,
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
or
$ clang+llvm-3.7.0-x86_64-linu
