[cfe-dev] Clang++ 3.4 -fdump-record-layouts not producing any results?

[Dun Peal]

Thanks, guys. -emit-llvm-only seems to do the trick, with the added benefit
of suppressing the generation of object files.

Where are these flags documented?  I looked through both `man clang` and
the online User Manual[1], and neither mentioned those flags.
