Reading what the JIT actually did: the columns of -XX:+PrintCompilation and its flag characters, -XX:+PrintInlining and its verdict strings, -XX:+LogCompilation with JITWatch, the -Xlog:jit+compilation and JFR forms, targeted compiler directives, and turning a refusal into a code change. Use when a hot method is suspected of not reaching tier 4, when a call site shows "too big" or another inlining refusal, when a method never appears in the compilation log at all, when someone prescribes…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Compilation and Inlining Logs ## Purpose Read the compiler's own output instead of guessing at it. Three diagnoses look alike from the outside and lead to three different flags: the method never became native code at all; a specific call inside a tree that compiled fine was not inlined; or code that was already generated got invalidated afterwards. Confusing them is how a session ends with the wrong flag changed. The failure this prevents is the plausible-looking command that silently answers nothing — a tier filter on the wrong field, `-Xlog:jit` with no sub-tag, a JFR recording whose threshold drops every compilation, a directive that only applies to compilations that have not happened yet — and is then read as "there is nothing to see". ## Workflow 1. **Decide which question you are asking**, and reuse relevant existing captures before collecting more. For compilation-attempt timing and tier, use `PrintCompilation` or `-Xlog:jit+compilation`; their attempt headers precede completion, so confirm the outcome before claiming installed code. Use `PrintInlining` or `-Xlog:jit+inlining=debug` for decisions within an attempt. Currently listed nmethods and …

How to install
mdr add robsonkades/agent-skills/compilation-and-inlining-logs@sha256:4a9806b90e25a171The line at the top of this page pins the label git:20260927.9ecadfd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
