CRUNCHIDE(1) FreeBSD General Commands Manual CRUNCHIDE(1)

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

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

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

crunchgen(1), ld(1)

The crunch utility was written by James da Silva <jds@cs.umd.edu>.

Chris Demetriou <cgd@netbsd.org> reorganized crunchide so that it supported multiple object formats, and added ELF object support and ECOFF object recognition.
