Frequently Asked Questions about analyzing-compiler-graphs

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I inspect Graal compiler graphs to analyze inlining decisions?▼

To analyze Graal compiler graphs, you dump Graal IR and use Seafoam or bgv2json workflows. This reveals optimization decisions like inlining and escape analysis to guide performance fixes in Truffle language implementations.

What is the best way to reveal missed Graal IR optimizations during Truffle language profiling?▼

Revealing missed Graal IR optimizations involves dumping and analyzing BGV files to inspect deoptimizations and boxing behavior. This exposes optimization barriers at the IR level to drive targeted improvements.

Do I need Graal debug options enabled to dump compiler graphs for escape analysis?▼

Yes, you need access to Graal debug options to dump compiler graphs for escape analysis. Optionally applying method filtering allows for focused dumps when inspecting optimization decisions across Graal languages.

Can I use BGV dumps with Seafoam workflows to inspect boxing removals?▼

Yes, you can use BGV dumps with Seafoam workflows to inspect boxing removals. This combination helps performance engineers understand which optimizations were applied or missed during Truffle/Graal compilations.

How to identify optimization barriers in Truffle language implementations using BGV dumps?▼

Identifying optimization barriers in Truffle implementations using BGV dumps requires analyzing Graal IR compiler graphs. Applying method filtering focuses the dumps to reveal specific deoptimizations and escape analysis failures.
