Rework of the riscv64-linux CI build to use CMake cross-compilation on a standard `ubuntu-24.04` runner, rather than a native RISE runner. ## What changed **`ci/docker/Dockerfile.riscv64-linux`** (new): - Ubuntu 24.04 base — has `crossbuild-essential-riscv64` in its package repos - Sets `CC=riscv64-linux-gnu-gcc` / `CXX=riscv64-linux-gnu-g++` so CMake detects cross-compilation and causes LLVM to build a native `llvm-tblgen` first, then cross-compile the rest of the toolchain - Sets `CARGO_TARGET_RISCV64_UNKNOWN_LINUX_GNU_LINKER` for Rust cross-builds - `XDG_CACHE_HOME=/tmp/cache` avoids write permission issues in the container **`ci/docker-build.sh`**: - Select `ci/docker/Dockerfile.<artifact>` if it exists, fall back to the default `ci/docker/Dockerfile` - Make the wasmtime volume mount conditional on `WASI_SDK_CI_SKIP_SYSROOT != 1` **`.github/workflows/main.yml`**: - New `riscv64-linux` matrix entry: `os: ubuntu-24.04`, `rust_target: riscv64-unknown-linux-gnu` - `cross_cmake_args: -DCMAKE_SYSTEM_NAME=Linux -DCMAKE_SYSTEM_PROCESSOR=riscv64 -DWASI_SDK_LLDB=OFF` - `WASI_SDK_CI_SKIP_SYSROOT: 1` - Handle `cross_cmake_args` in the cmake flags step ## Why WASI_SDK_CI_SKIP_SYSROOT The cross-compiled clang runs on riscv64, not on the x86_64 build host, so the wasm sysroot step is skipped. ## Why WASI_SDK_LLDB=OFF Avoids cross-compiling libedit and libxml2 in this first iteration; can be re-enabled as a follow-up.
