/* -----------------------------------------------------------------------------
*
* (c) The GHC Team, 2008-2009
*
* Event log format
*
* The log format is designed to be extensible: old tools should be
* able to parse (but not necessarily understand all of) new versions
* of the format, and new tools will be able to understand old log
* files.
*
* The canonical documentation for the event log format and record layouts is
* the "Eventlog encodings" section of the GHC User's Guide.
*
* To add a new event
* ------------------
*
* - In this file:
* - give it a new number, add a new #define EVENT_XXX
* below. Do not reuse event ids from deprecated event types.
*
* - In EventLog.c
* - add it to the EventDesc array
* - emit the event type in initEventLogging()
* - emit the new event in postEvent_()
* - generate the event itself by calling postEvent() somewhere
*
* - Describe the meaning and encoding of the event in the users guide
* (docs/user_guide/eventlog-formats.rst)
*
* - In the Haskell code to parse the event log file:
* - add types and code to read the new event
*
* -------------------------------------------------------------------------- */
