Vl-plainarglist-lvaluecheck

Check well-formedness of lvalues in a vl-plainarglist-p.

Signature

(vl-plainarglist-lvaluecheck x loc instname warnings) 
  → 
new-warnings

Arguments

x — Guard (vl-plainarglist-p x).

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

Returns

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

We check the lvalues throughout x for well-formedness in the sense of vl-expr-lvaluep, and generate non-fatal warnings for any problematic lvalues encountered.
