Hello John,

That is the option that gets passed to cc1plus or whatever the compiler driver is called.  I get that error message whenever I try to use llvm-g++ with the --emit-llvm option enabled.

Thanks for trying anyway,


Moving to your other issue, are you sure that -emit-llvm-bc 

> is the right option name?  Isn't it just -emit-llvm?  I seem to recall 
> reading about an -emit-llvm-bc option but then discovering that the document was
