Vl-modulelist-toplevel

(vl-modulelist-toplevel x) gathers the names of any modules that are defined in the module list x but are never instantiated in x, and returns them as an ordered set.

Signature

(vl-modulelist-toplevel x) → names

Arguments

x — Guard (vl-modulelist-p x).

Returns

names — Type (string-listp names).

Memoized. Cleared in vl-scopestacks-free.
