Serge Guelton 6a3f368498 Re-commit rL353927, patch included ... Make llvm::Optional<T> trivially copyable when T is trivially copyable This is an ever-recurring issue (see https://bugs.llvm.org/show_bug.cgi?id=39427 and https://bugs.llvm.org/show_bug.cgi?id=35978) but I believe that thanks to https://reviews.llvm.org/D54472 we can now ship a decent implementation of this. Basically the fact that llvm::is_trivially_copyable has a consistent behavior across compilers should prevent any ABI issue, and using in-place new instead of memcpy should keep compiler bugs away. This patch is slightly different from the original revision https://reviews.llvm.org/rL353927 but achieves the same goal. It just avoids going through std::conditional which may the code more explicit. llvm-svn: 353962		2019-02-13 18:12:04 +00:00
