Summary#

Intermittent pass failures are expensive when the only artifact is a top-level crash or vague error string. A reusable approach is to capture IR snapshots around failing passes, emit structured diagnostics, and provide an automated reduction path so engineers can shrink failures into reproducible test cases instead of debugging production-sized inputs blind.

Problem#

Compiler and model-conversion pipelines fail inside many-pass transformations, but the failing intermediate state is often discarded, making root cause analysis slow and non-repeatable.

Solution#

Add pass instrumentation that records pre/post IR, structured failure reports, timing, verification hooks, and a reducer tool/script that turns crashing workloads into minimal reproducers.

Failure Modes#

  • Logging only the final exception without preserving intermediate IR
  • Producing debug dumps with no stable directory or schema for downstream tooling
  • Relying on manual repro creation instead of automated reduction
