;; This test checks that the asyncify-memory argument can pick which memory to use in asyncify.

(memory (export "memory") 1 1)
(memory (export "unused") 1 1)
(memory $mem (export "memory") 1 1)
(memory $ignore (export "unused") 1 1)

Indentation, and give them names. The names should make the test output easier to read. (Can update the output using ./scripts/update_lit_checks.py PATH-TO-TEST)
