[llvm-dev] Compilation issues

[vit9696 via llvm-dev]

Hi,

Thanks for a quick reply. I included the compilation log in the attachment for clarity. Just in case the compiler is the latest clang from Xcode 9.2.

$ clang --version
Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin17.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

The code that was added looks like the one below. I don’t think it is valid C++ regardless of the compiler used (and in fact clang 5.0, clang 7.0, gcc 7.0 fail to compile this example as well, and it makes good sense).
While it is a little off the topic, which compiler do you use that has no problems with this code? Perhaps it was dead code previously?

#include <utility>

struct A{};
struct B {
  const A a{};
  void m(B &&other) {
    a = std::move(other.a);
  }
};

int main() {
  B b1, b2;
  b2.m(std::move(b1));
}

Best wishes,
Vit
