Vl-ss-find-hidexpr-range!!

The exclamation marks are there to get your attention.

Signature

(vl-ss-find-hidexpr-range!! x ss) → (mv warning range)

Arguments

x — Guard (vl-expr-p x).

ss — Guard (vl-scopestack-p ss).

Returns

warning — Type (iff (vl-warning-p warning) warning).

range — Type (vl-maybe-range-p range).

This finds the range of the datatype of the given hid, using vl-datatype-range. In code that is not aware of multidimensional arrays/vectors, you should use vl-ss-find-hidexpr-range (without the exclamation marks) instead; it finds the datatype range using vl-datatype-range-conservative which will correctly produce warnings when the datatype is multidimensional.
