Google Chrome V8 Javascript engine contains assembler from Sun

There has been lot of talk about the new Google Chrome's Javascript virtual machine called V8 . I just glanced at the google chrome's third party software licenses and was surprised to see that V8 assembler is licensed from Sun Microsystems. Sun made no news about it and it is another example of great innovation coming from Sun.

Update: I just checked the source code of V8 and it indeed contains Sun's source code. Check out assembler.cc . Also check the wikipedia entry for V8.
