Vl-expr-to-svex-selfdet

Translates a VL expression to svex in a self-determined context, perhaps with a context size.

Signature

(vl-expr-to-svex-selfdet x ctxsize ss scopes) 
  → 
(mv vttree svex size)

Arguments

x — Guard (vl-expr-p x).

ctxsize — Guard (maybe-natp ctxsize).

ss — Guard (vl-scopestack-p ss).

scopes — Guard (vl-elabscopes-p scopes).

Returns

vttree — Type (and (vttree-p vttree) (sv::svarlist-addr-p (sv::constraintlist-vars (vttree->constraints vttree)))) .

svex — Type (and (sv::svex-p svex) (sv::svarlist-addr-p (sv::svex-vars svex))).

size — Size if available. If not, we've already warned about it.
    Type (maybe-natp size).

This function sign- or zero-extends the result so that other functions can assume all bits of it are good.
