Vl-taskdecl-check-undeclared

Check an arbitrary vl-taskdecl-p for uses of undeclared names.

Signature

(vl-taskdecl-check-undeclared x st warnings) → new-warnings

Arguments

x — Guard (vl-taskdecl-p x).

st — Guard (vl-implicitst-p st).

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

Returns

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

This is nearly identical to vl-fundecl-check-undeclared and it has the same problems with parameters.
