Vl-expr-size-assigncontext

Vl-atom-size-assigncontext

Check and size an atom in an unpacked type context.

Signature
(vl-atom-size-assigncontext lhs-type x ss ctx warnings) → (mv successp new-x new-warnings)
Arguments: lhs-type — Guard (vl-datatype-p lhs-type).; x — Guard (vl-expr-p x).; ss — Guard (vl-scopestack-p ss).; ctx — Guard (vl-context-p ctx).; warnings — Guard (vl-warninglist-p warnings).
Returns: successp — Type (booleanp successp).; new-x — Type (vl-expr-p new-x).; new-warnings — Type (vl-warninglist-p new-warnings).
