-emit-llvm causes Clang to emit bitcode instead of object files, and 
LLVM IR instead of textual assembly. The LDC equivalents are -output-ll 
and -output-bc, respectively.

I don't think I have used the report you mention myself, so I'm unsure 
how it relates to that – could you give an example or a link to the 
corresponding Clang documentation?
