Adds the @syscall intrinsic for making direct OS syscalls from Rue code. This intrinsic requires the unchecked_code preview feature and a checked block. Implementation: - Added syscall to KnownSymbols - Added analyze_syscall_intrinsic in sema.rs with type checking (all args must be u64) - Added x86_64 codegen using the syscall instruction - Added aarch64 codegen using SVC #0x80 instruction - Added spec section 9.2 for syscall intrinsic documentation - Added spec tests for basic functionality Known issues filed as rue-8qt6: - checked block type inference with intrinsic return values - syscall with max arguments test 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
