+Subject: Install BytecodeArray last in SharedFunctionInfo
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Maglev assumes that when a SharedFunctionInfo has a BytecodeArray,
+then it should also have FeedbackMetadata. However, this may not
+hold with concurrent compilation when the SharedFunctionInfo is
+re-compiled after being flushed. Here the BytecodeArray was installed
+on the SFI before the FeedbackMetadata and a concurrent thread could
+observe the BytecodeArray but not the FeedbackMetadata.
+
+Drive-by: Reset the age field before setting the BytecodeArray as
+well. This ensures that the concurrent marker will not observe the
+old age for the new BytecodeArray.
+
