[cfe-dev] Question about stripping address-space qualifier with C++

[mats petersson]

What is the overall problem you are trying to solve? In general,
adress space casts either generate no code (no problem) or will modify
the behaviour of the code (necessary for correct operation). I don't
see much point in fixing the former, and breaking things by "fixing"
the latter doesn't seem like a brilliant idea either...

Can you give an example of C++ code that uses address space casts, and
that you want to remove them in?

(Caveat, I work on OpenCL, and we do use address space casts quite a bit)
