#include "logging/logTag.hpp"

/*
 * This file declares the Unified Logging (UL) tag sets for JFR.
 *
 * The JFR_LOG_TAG_SET_LIST macro will generate an enum
 * (zero-based ordinals) for these log tag sets.
 * Log tag set order (enum ordinals) is important
 * because we need to mirror this order in Java.
 *
 * Adding a new log tag set:
 *
 * 1. Ensure the log tag primitive which you attempt to use in your new log tag set is defined to UL.
 *    UL log tags are defined in logging/logTag.hpp.
 * 2. Append the new log tag set to the JFR_LOG_TAG_SET_LIST macro in this file.
 * 3. Make the corresponding change in Java by updating jdk.jfr.internal.LogTag.java
 *    to add another enum instance with a corresponding tag id ordinal.
