flag use-ghc-trace-events
  description:
    Use the package 'ghc-trace-events'. Disabling this flag makes it much easier to use @ghc-stack-profiler@ on the @ghc@ codebase, as
    we don't have to package 'ghc-trace-events' for hadrian. Always enabled on GHC <9.12.

  manual: True
  default: True

flag control
  description:
    Enable @eventlog-socket@ control commands.

  manual: True
  default: False
