Vl-blockitem-check-undeclared

Check for undeclared wires in an arbitrary vl-blockitem-p, and extends decls with the newly declared name.

Signature

(vl-blockitem-check-undeclared x st warnings) 
  → 
(mv new-warnings new-st)

Arguments

x — Arbitrary block item to process.
    Guard (vl-blockitem-p x).

st — Guard (vl-implicitst-p st).

warnings — Guard (vl-warninglist-p warnings).

Returns

new-warnings — Type (vl-warninglist-p new-warnings).

new-st — Type (vl-implicitst-p new-st).
