elderheim 0.30.0 Release Notes

Status

This is the text-runtime stop for elderheim.

Highlights

• Text runtime ABI for printing strings, signed integers, and floating-point
  values.
• Cranelift object generation for supported PRINT expressions.
• Temporary Linux/macOS executable linking through the host C compiler.
• CLI --emit executable mode for the current text-output subset.
• Checked constant arithmetic for emitted PRINT expressions, including
  division-by-zero and integer-overflow rejection before object emission.
• Hardened temporary linker behavior: absolute compiler path resolution,
  bundled runtime C source, and live temporary object files through link.
• --emit ast and --emit semantic now require --allow-internal-emit.
• Unsupported executable semantics such as assignments and control flow still
  fail closed in codegen.

Compatibility

0.30.0 is still not a full BASIC compiler. It adds the first linked
text-output path while assignments, control-flow execution, and broad dialect
compatibility remain later stop points.

The host C compiler linker path is temporary. The final supported release path
is still one downloadable elderheim binary per OS/architecture, with no Rust,
rustc, Cargo, C compiler, or external linker requirement where platform
constraints allow it.
