LuaJIT is a Just-In-Time (JIT) compiler for the Lua programming language, RISC-V is a free and open ISA enabling a new era of processor innovation.

Find latest LJRV release at IgnotaYun/LuaJIT,v2.1-riscv64. Development branch is avaliable at IgnotaYun/LuaJIT,riscv.

This is the release branch of LJRV, containing patchset based on dev branch commit 1ce02ddf8b6e ("riscv(interp): fix cdata matching handler in BC_ISEQV & BC_ISNEV"), based off LuaJIT v2.1 rolling 194d7f2d635a ("Merge branch 'master' into v2.1")

LJRV is a ongoing porting project of LuaJIT to the RISC-V 64-bit architecture by ISRC, ISCAS. The ultimate goal is to provide a RISC-V 64 LuaJIT implementation and have it upstreamed to the official LuaJIT repository.

LJRV is built and packaged in the same way as LuaJIT, requires a recent toolchain based on GCC or Clang with RISC-V 64 support and GNU Make. For building and installation instructions, please refer to the LuaJIT README.

For distro maintainers and packagers, we encourage one to follow our branch and patchset, as we would keep it up-to-date with the latest LuaJIT upstream. Cherry-picking and backporting is strongly discouraged, "no matter how self-standing individual changes look (because they often are not)".

• Interpreter Runtime
• JIT Compiler

LJRV is still considered of beta quality, take it with a grain of salt.

FFI struct passing is known to be partially broken, please report any issue you encounter.
