VRP in release version of GCC

[nkavv@physics.auth.gr]

If you visit the following:
http://gcc.gnu.org/gcc-4.0/changes.html

a reference is found to value range propagation pass. However, $GCCHOME/gcc
directory doesn't contain the required files (e.g. tree-vrp.c).

Is this an addition for a scheduled (pre)release or i just can't find it in the
released gcc-4.0.0 ??

thanks
