Vl-bindelim-main

Signature

(vl-bindelim-main x ss ctx itbl delta genp warnings) 
  → 
(mv warnings new-x delta)

Arguments

x — A single bind to process.
    Guard (vl-bind-p x).

ss — Scopestack where x occurs.
    Guard (vl-scopestack-p ss).

ctx — Where x occurs, for error messages.
    Guard (vl-bindcontext-p ctx).

itbl — For identifying local binds that we can handle.
    Guard (vl-bindelim-insttable-p itbl).

delta — The changes we're building.
    Guard (vl-binddelta-p delta).

genp — Are we in a generate?.
    Guard (booleanp genp).

warnings — For collecting warnings about unsupported binds.
    Guard (vl-warninglist-p warnings).

Returns

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

new-x — A list of binds to replace X. This will be NIL when x is a supported bind that has been converted into an intent and added to the delta. It will be (list x) if it isn't supported.
    Type (vl-bindlist-p new-x).

delta — Extended delta to apply in Pass 2.
    Type (vl-binddelta-p delta).
