  This version is intended for compiler hackers only.  We are in the midst
  of substantial structural changes, and this is a snapshot.  It only
  supports the Sparc, Alpha, and HPPA architectures.  Furthermore, there
  are performance bugs that have to be fixed.  We recommend that if you
  want to use a working version, then you should use 110.10 until further

  Because of stability problems, we have backed out of the 110.10 FLINT
  changes (there are bad interactions between these changes and the
  literal lifting and new array representations).  The compiler now
  generates code directly into code objects (instead of into an array
  that later gets copied into the code object)  The greatly reduces the
  GC activity during big compiles.


  The MLRISC directory structure has been reorganized. All the
  optimization modules and their interfaces are in separate
  directories. Each instantiation of the optimization modules 
  for a specific architecture will follow the same directory
  structure. Thus the register allocator and its interfaces
  are under MLRISC/ra, and its instantiation for the DEC Alpha
  under MLRISC/alpha32/ra; etc.
