test/wasm/export-optional-lazy.ll

; Optional linker-synthetic symbols are only created if they are undefined
; in the final output.
; This test is for a regression where an explict --export of an lazy archive
; symbol caused an undefined referece to an optional symbol to occur *after*
; the optional symbols were created.
