Vl-modinst-blankargs

Apply the blankargs transform to a module instance.

Signature

(vl-modinst-blankargs x ss nf warnings) 
  → 
(mv warnings new-x vardecls nf)

Arguments

x — Guard (vl-modinst-p x).

ss — Guard (vl-scopestack-p ss).

nf — Guard (vl-namefactory-p nf).

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

Returns

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

new-x — Type (vl-modinst-p new-x).

vardecls — Type (vl-vardecllist-p vardecls).

nf — Type (vl-namefactory-p nf).

This is just a wrapper for vl-modinst-plainarglist-blankargs that takes care of looking up the ports for the module being instanced.
