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 plctlab/LuaJIT, branch riscv64-v2.1-branch or plctlab/LuaJIT, branch v2.1-riscv64. Development branch is avaliable at plctlab/LuaJIT, branch riscv.

This is the release patch branch of LJRV, containing patchset based on LJRV dev branch commit 7034c3226f92 ("riscv(support): cleanup softfloat and 32-bit endianness definition"), based off LuaJIT v2.1 rolling 93e87998b240 (" Update Nintendo Switch build script.")

LJRV is a ongoing porting project of LuaJIT to the RISC-V 64-bit architecture by PLCT Lab, 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. For production usage, you might want to disable the JIT compiler during compilation by setting XCFLAGS+= -DLUAJIT_DISABLE_JIT in Makefile or environment variable.

Please report bugs to Issues.
