Vl-expr-wildelim

Top-level wrapper for eliminating ==? and !=? from an expression. Avoids reconsing when there are no ==? or !=? operators.

Signature

(vl-expr-wildelim x ctx warnings) → (mv new-warnings new-x)

Arguments

x — Guard (vl-expr-p x).

ctx — Guard (vl-context-p ctx).

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

Returns

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

new-x — Type (vl-expr-p new-x).
