New Revision: 349209
URL: http://llvm.org/viewvc/llvm-project?rev=349209&view=rev
Log:
Add AddressSpace mangling to MS mode
All of the symbols demangle on llvm-undname and demangler.com. This
address space qualifier is useful for when we want to use opencl C++ in
Windows mode. Additionally, C++ address-space using functions will now
be usable on windows.
