The line you have works fine for me.  There have been a lot of changes  
related to debug info recently so make sure you are up to date.   
Beyond that we'd need information about your environment to help.

Note that -emit-llvm asks for LLVM intermediate representation as  
output; but it has no effect without -c  or -S.  Combined with -c it  
produces binary format LLVM IR; you should not expect this to be  
executable.
