Yes, of course; that's what everyone is talking about, I think.  "Emit" 
here may also mean "cache in memory some place", rather than "write to a 
file".  It could mean, for example, fill in the data structures we 
already use for types in dwarf2out.c early, and then throw away the 
front-end type information.
