The
lorder
utility uses
nm(1)
to determine interdependencies in the list of object files
specified on the command line.
Lorder
outputs a list of file names where the first file contains a symbol
which is defined by the second file.
The output is normally used with
tsort(1)
when a library is created to determine the optimum ordering of the
object modules so that all references may be resolved in a single
pass of the loader.
