            Bug ID: 23325
           Summary: [ms] manging mismatch with cl
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: nicolasweber at gmx.de
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

This is mangled differently by clang-cl and cl:

struct SkPoint {};
class SkXfermode {};
class SkPaint {};

class SkCanvas {
 protected:
  void onDrawPatch(const SkPoint cubics[12], const SkPoint texCoords[4],
                   SkXfermode* xmode, const SkPaint& paint);
};

void SkCanvas::onDrawPatch(const SkPoint cubics[12], const SkPoint
texCoords[4],
                           SkXfermode* xmode, const SkPaint& paint) {}

(The two manglings do demangle to the same thing though :-/)
