--- Comment #6 from Justin Michaud <justin_michaud at apple.com> ---
The following program exhibits different behavior on Mac/iOS:

out.wat:

(module
  (func (export "test") (result f64)
    f64.const 42
    f64.const 42
    i32.const -1
    i32.const -1
    i32.eq
    select
))

out.js:
import { test } from 'out.wasm'

print("test: " + test())

Run as module with --wasmBBQUsesAir=0 --defaultB3OptLevel=0 to reproduce. iOS gives 0, Mac gives 42.
