CRUNCHIDE(1)            NetBSD General Commands Manual            CRUNCHIDE(1)


NAME

     crunchide -- hides symbol names from ld, for crunching programs together


SYNOPSIS

     crunchide [-f keep-list-file] [-k keep-symbol] object-file
               [object-file ...]


DESCRIPTION

     crunchide 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.

     crunchide is designed as a companion program for crunchgen(1), which
     automates the process of creating crunched binaries from multiple compo-
     nent programs.
