+# === Fix the SM38 tracelogger ===
+# This patch is a squashed version of several patches that were adapted
+# to fix failing hunks.
+#
+# Applied in the following order, they are:
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1223767
+#    Assertion failure: i < size_, at js/src/vm/TraceLoggingTypes.h:210 
+#    Also fix stop-information to make reduce.py work correctly.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1227914
+#    Limit the memory tracelogger can take.
+#    This causes tracelogger to flush data to the disk regularly and prevents out of 
+#    memory issues if a lot of data gets logged.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1155618
+#    Fix tracelogger destructor that touches possibly uninitialised hash table.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1223636
+#    Don't treat extraTextId as containing only extra ids.
+#    This fixes an assertion failure: id == nextTextId at js/src/vm/TraceLoggingGraph.cpp
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1227028
+#    Fix when to keep the payload of a TraceLogger event.
+#    This fixes an assertion failure: textId < uint32_t(1 << 31) at js/src/vm/TraceLoggingGraph.h
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1266649
+#    Handle failing to add to pointermap gracefully.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1280648
+#    Don't cache based on pointers to movable GC things.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1224123
+#    Fix the use of LastEntryId in tracelogger.h.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1231170
+#    Use size in debugger instead of the current id to track last logged item.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1221844
+#    Move TraceLogger_Invalidation to LOG_ITEM.
+#    Add some debug checks to logTimestamp.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1255766
+#    Also mark resizing of memory.
+# * https://bugzilla.mozilla.org/show_bug.cgi?id=1259403
+#    Only increase capacity by multiples of 2.
+#    Always make sure there are 3 free slots for events.
