MoonBit supports the LLVM backend. With this, it achieved 8× Java’s performance in FFT and introduced out-of-the-box debugging with DWARF symbol injection, enabling precise source mapping directly to compiled outputs.
MoonBit will soon compile directly to native binary files without relying on a C compiler. This eliminates various compatibility issues associated with C compilers.
Does this mean MoonBit will get JIT support soon?
we have a interpreter mode which takes advantage of tcc for fast interpretion
I assume there was a C backend before — some numbers comparing that and the wasm backend with LLVM would’ve been helpful."
The LLVM mode currently is not good as C backend, but we are working on it to bring it comparable to C backend
It's great to see MoonBit adopt llvm, but is it relying on a c compiler or independent?
"Once support for distributing precompiled runtime libraries is implemented, MoonBit programs will be completely independent of the C compiler, generating native executables using only a linker."
we used to output C for native backend support
Wonder how the LLVM backend affects compile times. Anyone tried it yet?
it is not the optimial, for fast native mode, we rely on tcc for fast interpretion
How does MoonBit’s LLVM backend compare to Zig or Rust?
"The LLVM backend seems like a natural fit for MoonBit, but I wonder how it handles complex optimizations like inlining and dead code elimination. Has anyone benchmarked it against other LLVM-based languages?"
