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.
