            Bug ID: 48842
           Summary: Wrong alignment of __declspec(align)ed typedef with
                    reduced alignment
           Product: clang
           Version: 11.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C
          Assignee: unassignedclangbugs at nondot.org
          Reporter: ju.orth at gmail.com

                    richard-llvm at metafoo.co.uk

Consider

__declspec(align(2)) typedef int A;

int f(void) {
        return _Alignof(A);
}

msvc returns 4, clang returns 2 on the x86_64-pc-windows-msvc target.
