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 component programs.
