Hi, compiling llvm-10 code with this change causing compilation errors:
../../third_party/swiftshader/third_party/llvm-10.0/llvm/include/llvm/ADT/Optional.h:289:8:
error: cannot overload a member function with ref-qualifier '&&' with a member
function without a ref-qualifier
289 | auto map(const Function &F) &&
| ^
../../third_party/swiftshader/third_party/llvm-10.0/llvm/include/llvm/ADT/Optional.h:272:8:
note: previous declaration is here
272 | auto map(const Function &F) const
| ^
Code snippet:
template <typename T> class Optional {
...
template <class Function>
auto map(const Function &F) &&
-> Optional<decltype(F(std::move(*this).getValue()))> {
if (*this) return F(std::move(*this).getValue());
return None;
}
...
}
Is it intentional?
