The only mail I found about the mangling was
http://communities.mentor.com/community/cs/archives/cxx-abi-dev/msg02351.html
but the ABI document at least on the web hasn't been updated.
If li is the operator name, then I'd think instead of
_Z4li_wPKc
we should mangle it as
_Zli2_wPKc
- i.e. "li" followed by <length,ID> pair would be <operator-name> (and have
support for this in the demangler).
Jason, can this be resolved on cxx-abi-dev and for 4.7.0-RC2?  Sounds like a
blocker to me for 4.7.0, releasing udlit support which is mangled incorrectly
would be very bad, especially when it clashes with user function.s
