GCC Cauldron: Notes from the C++ ABI BOF

[Cary Coutant]

string & list changes

- function w/ string arg
- classes w/ string members
- global variables

- link c++98 & c++0x together
- link existing c++98 .o & new c++-x .o
- link at runtime c++98 .so & new c++0x .so

HP: attribute on type propagates to:
- function (params or return type)
- structs w/ members
- global vars
"Function-level versioning"
