I think the mangling itself is fine.

However, I still think that it is important to have aliasing directives 
for the assembler so that whatever name-mangling you use does not reach 
object files on systems with the appropriate assembler support.  And, I 
still think you should commit to those improvements as part of the work 
that you are doing.  In particular, I don't think you should make 
changes to G++ that make these new mangled names show up on GNU/Linux 
systems, provided people have new enough assemblers.  If you will do 
this, it will help both LTO and IMA.

Since you've complained in the past that people have objected to some of 
your changes only after you have checked in patches, I want to make it 
clear that I'm objecting now.

Thanks,
