Vl-depgraph-fix

(vl-depgraph-fix x) is an ACL2::fty alist fixing function that follows the fix-keys strategy.

Signature

(vl-depgraph-fix x) → fty::newx

Arguments

x — Guard (vl-depgraph-p x).

Returns

fty::newx — Type (vl-depgraph-p fty::newx).

Note that in the execution this is just an inline identity function.
