[PATCH] D155870: [Clang][CodeGen] Another follow-up for `vtable`, `typeinfo` et al. are globals

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added a comment.

`__dynamic_cast` is part of standard C++ library. If we ever implement it for GPU, chances are we will use libc++abi with the same signature as other targets, i.e., the 2nd and 3rd arguments are generic pointers.

I feel it is safer to do an address space cast when calling the function instead of changing its signature.
