Vl-idexpr

Construct an vl-idexpr-p.

Signature

(vl-idexpr name finalwidth finaltype) → expr

Arguments

name — Guard (stringp name).

finalwidth — Guard (maybe-natp finalwidth).

finaltype — Guard (vl-maybe-exprtype-p finaltype).

Returns

expr — Type (vl-expr-p expr).

(vl-idexpr name finalwidth finaltype) constructs a simple identifier expression with the given name, width, and type.

I didn't always hons these, but now it seems like a good idea since the same identifier may be needed in several contexts, and since we often want to construct fast alists binding identifiers to things, etc.
