Serviceable Runtimes
summary
Shows how to add Eclipse OMR’s DDR debugging to a new runtime by generating a DDR blob and embedding a tiny eye‑catcher structure so DDR Interactive finds the VM in core dumps. Covers the DDR gen step that reads DWARF/debug symbols to emit the blob and the Java superset classes DDR Interactive uses, and contrasts DDR’s cross‑version, cross‑platform introspection with gdb. Demos a quick prototype on a tiny Base9 runtime, explains stack slots output, plugins and a GC check analyzer.
