# The compiler front-end passes all object files, archive files, and shared
# library files named on the command line to CreateExportList to create a
# list of all symbols to be exported from the shared library. This causes
# all archive members to be copied into the shared library whether they are
# needed or not. Instead we run the tool ourselves to pass only the object
# files so that we export only the symbols actually provided by the sources.
