Sorry this has taken so long to get back to... We're still digging out a bit from the patches queued while preparing for the gcc5 release.

So I guess at some level it's not clear to me why we need to support the @ operator in libcc1. So perhaps starting with a justification for wanting/needed that capability would be helpful. And just to be clear, I'm an avid fan of '@' in gdb, so you can assume I already know what it does and accept that it's a good thing in gdb.

As for the patch itself, you noted you weren't sure if copy_node was right, it would help if you'd describe what problem you were having that's solved by copying the node. I wonder if you should be building up a node from scratch here.

In general, please use C style comments rather than C++. It's a nit and may change one day, but the general consensus has been to stick with old-style comments for now.
