            Bug ID: 24559
           Summary: GNU attributes after declspecs don't parse
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: hans at chromium.org

With clang-cl, this parses fine:

  struct __attribute__((lockable)) __declspec(dllexport) S { };

while this does not:

  struct __declspec(dllexport) __attribute__((lockable)) T { };

/tmp/a.cc(3,1) :  error: declaration of anonymous struct must be a definition
struct __declspec(dllexport) __attribute__((lockable)) T { };
/tmp/a.cc(3,1) :  warning: declaration does not declare anything
struct __declspec(dllexport) __attribute__((lockable)) T { };

It would be great if we could allow both orderings, or at least provide a
better error message.
