Expose all EventLog events as DTrace probes
- Defines a DTrace provider, called 'HaskellEvent', that provides a probe
for every event of the eventlog framework.
- In contrast to the original eventlog, the DTrace probes are available in
all flavours of the runtime system (DTrace probes have virtually no
overhead if not enabled); when -DTRACING is defined both the regular
event log as well as DTrace probes can be used.
- Currently, Mac OS X only. User-space DTrace probes are implemented
differently on Mac OS X than in the original DTrace implementation.
Nevertheless, it shouldn't be too hard to enable these probes on other
platforms, too.
- Documentation is at http://hackage.haskell.org/trac/ghc/wiki/DTrace
