Core is GHC’s intermediate language. Reading Core can help you better understand the performance of your program. Someone asked me for documentation or tutorials on reading Core, but I couldn’t find much.
What documentation is available for reading GHC Core?
Here’s what I’ve found so far:
- Write Haskell as fast as C: exploiting strictness, laziness and recursion
- Haskell as fast as C: working at a high altitude for low level performance
- RWH: Chapter 25. Profiling and optimization
- High-Performance Haskell talk at CUFP (slide 65-80)
