[GCC-XML] Determining template parameter types

[Chris Waldron]

Brad,

  I'm interested in at least taking a look at the effort required to
implement this feature.  Can you point me in the right direction?

Thanks,
Chris

There are two reasons I've held off doing this:

1.)  The real solution is to have full dumping of uninstantiated
templates.  Specification of arguments used for instantiation should be
in a form that references the template and then lists references to the
arguments.

2.)  The project that funds gccxml development doesn't need it.

If anyone wants to contribute support for templates I can help get you
started.
