No, that's not C++ name mangling.  That's C symbol shortening 
(/NAMES=SHORTENED) which happens to be the same treatment extern "C" 
symbols get under C++.  True name mangling is a different and more 
complicated beast and I don't think even uses the same algorithm on 
Alpha and Itanium.  Part of the confusion arises from the fact that 
both shortened symbols and mangled symbols get stored in the so-called 
name mangler database ([.CXX_REPOSITORY]CXX$DEMANGLER_DB by default).

FWIW, I also made a Perl implementation of symbol shortening that is 
used to build the linker options file for the shareable image that 
implements the Perl interpreter:
