Function compile_to_elf

tests/integration/qemu_execution.rs:159–182

Compile HLL source to the final assembled output and export it as an ELF image ready for qemu-riscv64. Uses two-stage compilation: compile stdlib and user code independently, then assemble and link through the pipeline.

    let user_obj = pipeline
        .assemble(&user_tokens)
        .unwrap_or_else(|e| panic!("user assembly failed: {e}"));

    let mut modules: Vec<(&str, &AssembledOutput)> =
        stdlib_objs.iter().map(|(n, o)| (n.as_str(), o)).collect();
