# This is used to generate stub entry points. We generate a file to
# be included in the declaraion and a file to be used for expanding macros
# to represent the implementation of the stubs.
#
# if "$entry_count" is ever changed and the .inc files regenerated then
# the following issues need to be addressed:
#
# 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.
# 3+247+5=255 This should get us in under the Linux ARM limitation
