This may be possible but implementing it will have to wait until full 
uninstantiated template dumping is implemented.  Likely the output 
representation for these two features will be linked.  Please submit 
this as a feature request here:

http://www.gccxml.org/Bug

so that it can be included if uninstantiated template dumping is ever 
implemented.

GCC-XML cannot generate instantiations...it is a read-only walk of GCC's 
representation.  It is up to the user to make sure desired tempaltes are 
instantiated in the input translation unit.
