test/lit/passes/no-inline-monomorphize-inlining.wast

;; NOTE: Assertions have been generated by update_lit_checks.py --all-items and should not be edited.

;; Monomorphization creates a new function, which we can then inline. When we
;; mark the original as no-inline, we should not inline the copy, as the copy
;; inherits the metadata.
;;
;; Use --optimize-level=3 to ensure inlining works at the maximum (to avoid it
;; not happening because of size limits etc.).
