[PATCH] D122434: [Support] Add OpauqeDataStore

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

This is like a heterogeneous list in FP. I also wonder whether we should use llvm::Any instead. We cannot use C++17 <https://discourse.llvm.org/t/rfc-increasing-the-gcc-and-clang-requirements-to-support-c-17-in-llvm/59983> std::any yet.
(Also, llvm::Any has the `LLVM_EXTERNAL_VISIBILITY` trick. I don't know how std::any behaves in various STL implementations in the presence of LLVM_LINK_LLVM_DYLIB)
