Presumably an empty path yields a length of 0, so this could probably be written
as:

if (!layoutObject())
  return 0;
return asPath().length();

Done.

+    path = asPath();
+  return path.length();
+}
+
+SVGPointTearOff* SVGGeometryElement::getPointAtLength(float length) {
+  document().updateStyleAndLayoutIgnorePendingStylesheets();
+  Path path;
+  if (layoutObject())

[fs, 2016/10/24 10:48:53]

Somewhat similar to above, I think this could be written more succinctly as:

FloatPoint point;
if (layoutObject())
  point = asPath().pointAtLength(length);
return ...;

[Shanmuga Pandi, 2016/10/26 09:52:12]

Done.

+    path = asPath();
+  FloatPoint point = path.pointAtLength(length);
+  return SVGPointTearOff::create(SVGPoint::create(point), 0,
+                                 PropertyIsNotAnimVal);
+}

 LayoutObject* SVGGeometryElement::createLayoutObject(const ComputedStyle&) {
   // By default, any subclass is expected to do path-based drawing.
   return new LayoutSVGPath(this);
