It has been brought to my attention that it might be advantageous
for some parts of the research community and the open source
community, that I make a public statement about the intellectual
property (IP) contained in LuaJIT 2.0 and earlier versions:

I hereby declare any and all of my own inventions contained in
LuaJIT to be in the public domain and up for free use by anyone
without payment of any royalties whatsoever. – Hashed profile counters: Bytecode instructions to trigger the
start of a hot trace use low-overhead hashed profiling counters. – Code sinking via snapshots: The VM must be in a consistent state
when a trace exits.
