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 f6d3bdbc4b8b ("riscv(jit,interp): correct math.{min,max} behavior with NaN"), based off LuaJIT v2.1 rolling f73e649a954b ("Merge branch 'master' into v2.1")
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.
