Source for native sun.misc.Unsafe operation in java

Question

I downloaded "openjdk-6-src-b23-05_jul_2011" to look at my own method implementations in sun.misc.Unsafe. e.g. compareAndSwapInt (...), but I can not find anything in the openjdk loaded sources. I want to get an idea of ​​what these methods look like (I was interested in the atomic material provided by jdk).

Can anyone point me to the right place (s)?

$ ls jdk/src/
linux  share  solaris  windows

$ ls hotspot/src/os/
linux  posix  solaris  windows

any help appreciated

Marcel
