Vl-vardecl-exprsize

Compute sizes and types of expressions throughout a vl-vardecl-p

Signature
(vl-vardecl-exprsize x ss warnings) → (mv successp warnings new-x)
Arguments: x — Guard (vl-vardecl-p x).; ss — Guard (vl-scopestack-p ss).; warnings — Guard (vl-warninglist-p warnings).
Returns: successp — Type (booleanp successp).; warnings — Type (vl-warninglist-p warnings).; new-x — Type (vl-vardecl-p new-x).
