prefetch instructions in Hotspot

[Mahmood Naderan]

OK I downloaded jdk source using 

   hg clone http://hg.openjdk.java.net/jdk6/jdk6 openjdk6
   cd openjdk6 && sh ./get_source.sh

Then I added the declarations into jdk/src/share/classes/sun/misc/Unsafe.java. I have to say that I removed the jdk packages from apt.

Now, before running 'make' in the jdk folder, do I have to point Hotspot location? How?

 
Regards,
Mahmood
