The
utility hides the global symbols of
object-file
such that they are ignored by subsequent runs of the linker,
ld(1).
Some symbols may be left visible via the
-k keep-symbol
and
-f keep-list-file
options.
The
keep-list-file
must contain a list of symbols to keep visible, one symbol per line.
The names given by
keep-symbol
or in
keep-list-file
should be C names.
For example,
to keep the C function
``foo''
visible, the option
``-k foo''
should be used.
The
utility is designed as a companion program for
crunchgen(1),
which automates the process of creating crunched binaries from
multiple component programs.
