           Product: WebKit

          Platform: All

gcc warning:
..\..\..\WebCore\rendering\RenderBoxModelObject.cpp: In member function 'void WebCore::RenderBoxModelObject::clipBorderSidePolygon(WebCore::GraphicsContext*, const WebCore::IntRect&, const WebCore::IntSize&, const WebCore::IntSize&, const WebCore::IntSize&, const WebCore::IntSize&, WebCore::BoxSide, bool, bool, const WebCore::RenderStyle*)':
..\..\..\WebCore\rendering\RenderBoxModelObject.cpp:1529:62: warning: operation on 'firstQuad[2]' may be undefined

This warning introduced in http://trac.webkit.org/changeset/63864 :

1528 firstQuad[2] = side == BSTop || side == BSBottom ? FloatPoint(quad[3].x(), quad[2].y())
1529            : firstQuad[2] = FloatPoint(quad[2].x(), quad[3].y());

Assignment in the false case of ternary condition is useless,
and evaluating of undefined firstQuad[2] cause this warning.
