michael@0: # 1) The current Linux ARM code has a limitation of only having 256-3 stubs,
michael@0: #    as a result of the limitations of immediate values in ARM assembly.
michael@0: #
michael@0: # This number is verified by the IDL parser in xpcom/idl-parser/xpidl.py, as
michael@0: # well as in xpcom/reflect/xptinfo/src/xptiInterfaceInfoManager.cpp, to
michael@0: # prevent generating interfaces or loading xpt files that would cause the
michael@0: # stubs to run off the entries.
michael@0: # If you change this number, please update that location.
michael@0: 
michael@0: # 3 entries are already 'used' by the 3 methods of nsISupports.
michael@0: # 3+247+5=255 This should get us in under the Linux ARM limitation
