I am pleased to announce TvmJIT (https://github.com/fperrad/tvmjit), a Virtual Machine derivated from LuaJIT (luajit.org). The only change between LuaJIT and TvmJIT is the frontend language. TvmJIT interprets the TP (Table Processing) language which uses the S-expression syntax. The TP language is a good choice for an intermediate language, it is not an end user language, but it is easy to parse and easy to generate.
TvmJIT has all features of LuaJIT like, FFI (Foreign Function Interface), JIT (Just In Time compilation), bytecode generation, Lua 5.1 API/ABI compatible. TvmJIT could use any Lua 5.1 native extension. In order to validate the concept of TvmJIT, I have already written in Lua a small NQP compiler (the AST node are close to the NQP ones), but it is a toy. The next step is to add a TvmJIT backend to https://github.com/perl6/nqp, I need help or/and advice for this. I make some experiment for generate TP from NQP, see https://gist.github.com/fperrad/5946991 Any feedback are welcome.
