+# 1) The current Linux ARM code has a limitation of only having 256-3 stubs,
+#    as a result of the limitations of immediate values in ARM assembly.
+#
+# This number is verified by the IDL parser in xpcom/idl-parser/xpidl.py, as
+# well as in xpcom/reflect/xptinfo/xptinfo.cpp, to prevent generating interfaces
+# or loading xpt files that would cause the stubs to run off the entries.
+# If you change this number, please update that location.
+
+# 3 entries are already 'used' by the 3 methods of nsISupports.
