tomevault-io Fetching Truffle Documentation
Searches official GraalVM, Truffle, and Graal compiler documentation to answer technical questions about APIs, performance optimization, and compiler behavior.
Primary Documentation Sources
GraalVM Official Docs: https://docs.oracle.com/en/graalvm/
- Language implementation guides
- Tools and utilities
- Performance optimization guides
GraalVM Tools Javadoc: https://www.graalvm.org/tools/javadoc/
- API reference for
com.oracle.truffle.api.*packages - Node implementations, frame management, interop protocols
Graal GitHub Repository: https://github.com/oracle/graal
- Truffle framework documentation in
/truffle/docs/ - Compiler documentation in
/compiler/docs/ - SimpleLanguage reference implementation
Key Documentation Paths
Performance Optimization:
/truffle/docs/Optimizing.md- Optimization strategies/truffle/docs/Profiling.md- Profiling tools/compiler/docs/- Graal compiler tuning
Truffle Framework:
/truffle/docs/LanguageTutorial.md- Language implementation guide/truffle/docs/DSL.md- Truffle DSL specializations/truffle/docs/BytecodeDSL.md- Bytecode DSL implementation
Compiler Options Quick Reference
Profiling and Tracing:
--engine.TraceCompilation- Log compilation events--engine.TracePerformanceWarnings- Detect optimization barriers--engine.TraceInlining- Show inlining decisions--cpusampler,--cputracer,--memtracer- Profiling tools
Diagnostic Options:
-Djdk.graal.Dump=Truffle- Dump compiler graphs-Djdk.graal.PrintGraph=File- Output format for graphs
When to Use This Skill
Search documentation when you need:
- Explanation of compiler flags or profiling tools
- API usage for Truffle DSL or Bytecode DSL
- Performance optimization strategies
- Understanding of compiler warnings or deoptimization causes
