Mats Brorsson (May 12 2023 at 12:06): Mats Brorsson (May 12 2023 at 12:06):I can build iwasm interpreter for RISC-V, but has anyone here succesfully configured and build any of the JIT or AOT options for RISC-V?
lum1n0us (May 14 2023 at 10:51):Hope it is useful
RISCV64, RISCV32 (RISC-V LP64 and RISC-V LP64D are tested) https://github.com/bytecodealliance/wasm-micro-runtime#supported-architectures-and-platforms

Well, as I wrote, I can build the interpreter but what about the JIT or AOT compilers? Those does not seem to be supported for RISCV64.
Wenyong Huang (May 25 2023 at 09:03):Hi, the LLVM AOT is also supported, please
Build iwasm:
64-bit: cmake -DWAMR_BUILD_TARGET=RISCV64/RISCV64_LP64D/RISCV_LP64
32-bit: cmake -DWAMR_BUILD_TARGET=RISCV32/RISCV32_ILP32D/RISCV_ILP32
Generate AOT file:
64-bit: wamrc --target=riscv64 --target-abi=lp64/lp64d -o test.aot test.wasm
32-bit: wamrc --target=riscv32 --target-abi=ilp32/ilp32d -o test.aot test.wasm
For LLVM JIT, I remember it is also supported, please try adding -DWAMR_BUILD_JIT=1 when building iwasm.
Mats Brorsson (May 25 2023 at 14:45):Thanks, I already have an LLVM installation. Can I use that or do I really need to build the llvm that is in the WAMR tree?
YAMAMOTO Takashi (May 26 2023 at 09:29):eg. cmake -DLLVM_DIR=/usr/local/opt/llvm@14/lib/cmake/llvm
Mats Brorsson (May 31 2023 at 06:00):Thanks, but should LLVM_DIR point to the LLVM source directory or something else?
YAMAMOTO Takashi (Jun 17 2023 at 18:08):it's the directory containing cmake files. eg LLVMConfig.cmake
i sometimes use a directory under llvm build tree. eg. build/lib/cmake/llvm
