Vl-unparam-sigalist-fix

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

Signature

(vl-unparam-sigalist-fix x) → fty::newx

Arguments

x — Guard (vl-unparam-sigalist-p x).

Returns

fty::newx — Type (vl-unparam-sigalist-p fty::newx).

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