This part of the wiki collects all the information related to debugging GHC: that includes debugging the compiler itself, the libraries, the runtime system, the code generator, or the build system.

  • Debugging the compiler itself. If you're debugging a compiler panic or some problem in GHC itself, then go to Debugging/Compiler
  • Performance debugging.
    • Debugging/ProfilingGhc: Profiling the compiler itself.
    • Debugging/TickyTicky: for debugging performance-related issues in compiled code. Typically for performance debugging of the Simplifier and Core-level optimisations.
    • Debugging/LowLevelProfiling: way to investigate low-level performance, typically for performance debugging of the code generator or RTS.
