Add riscv64im-unknown-openvm-elf as a tier 3 Rust target for the OpenVM zero-knowledge virtual machine (RV64IM ISA). The target includes std support via the OpenVM platform abstraction layer. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
GitHub Actions workflows to build and publish pre-built toolchain binaries for the riscv64im-unknown-openvm-elf target. - build-toolchain.yml: reusable workflow that builds stage-2 rustc with the custom target for a single platform - release-toolchain.yml: triggered on openvm-* tags, builds for 3 platforms (x86_64 Linux, aarch64 macOS, x86_64 macOS) and creates a draft GitHub Release with tarballs Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Bootstrap validates target triples before the compiler is built, but our built-in target only exists after compilation. Create a dummy JSON spec at RUST_TARGET_PATH to pass the sanity check. This is the same workaround used by SP1 and ZisK. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The host-target input could mismatch the actual runner architecture (macos-15 is ARM, not x86_64). Now the build workflow detects the host triple at runtime using uname. Also use macos-13 for the x86_64 macOS build (last Intel runner). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
