.Dd June 14, 1994 .Dt CRUNCHIDE 1 .Os BSD 4 .Sh NAME .Nm crunchide .Nd hides symbol names from ld, for crunching programs together .Sh SYNOPSIS .Nm crunchide .Op Fl f Ar keep-list-file .Op Fl k Ar keep-symbol .Op Ar object-file ... .Sh DESCRIPTION .Nm Crunchide hides the global symbols of .Ar object-file such that they are ignored by subsequent runs of the linker, .Xr ld 1 . Some symbols may be left visible via the .Fl k Ar keep-symbol and .Fl f Ar keep-list-file options. The .Ar keep-list-file must contain a list of symbols to keep visible, one symbol per line. Note that the C compiler prepends an underscore in front of symbols, so to keep the C function ``foo'' visible, the option ``-k _foo'' must be used.
