Replication Package: Do LLMs Understand Compiler Errors? A Compiler-Grounded Study of First-Diagnostic Control

Replication package for the ASE 2026 submission "Do LLMs Understand Compiler Errors? A Compiler-Grounded Study of First-Diagnostic Control." Contents:- 12,800 raw LLM outputs (8 models × 8 error types × 2 languages × 100 samples)- MSVP verification pipeline (deterministic compiler-based classification)- Prompt templates (generation, recognition, IBP, CDP, refinement)- Baseline results (rule-based mutation, 1-shot, chain-of-thought)- Cross-compiler analysis (gcc-14 vs clang-18)- Expert judgment survey data- All analysis scripts for reproducing tables and figures See README.md for setup and reproduction instructions.
