Author: smeenai Date: Wed Mar 1 20:51:27 2017 New Revision: 296729 URL: http://llvm.org/viewvc/llvm-project?rev=296729&view=rev Log: [libc++] Mark some std::num_get method templates inline
D29157 will make explicit template instantiations expand to default visibility, at which point these method templates will need to be explicitly marked hidden visibility to avoid leaking into other DSOs. Unfortunately, because of clang PR32114, they must be marked inline (in conjunction with `-fvisibility-inlines-hidden`) to actually hide them, since clang doesn't respect the hidden visibility annotation. Since this involves an ABI change, mark these methods inline in a separate change, so that the ABI changes can be reviewed separately and verified to be safe.
