Vl-expr-selects

Collects up all the selection expressions (bit-selects, part-selects, array indexing, and unresolved indexing) and returns them as a flat list of expressions.

Signature

(vl-expr-selects x) → selects

Arguments

x — Guard (vl-expr-p x).

Returns

selects — Type (vl-exprlist-p selects).

Note: we assume there are no nested selects.
