; Verify that LLJIT Platforms respect static initializers in cached objects.
; This IR file contains a static initializer that must execute for main to exit
; with value zero. The first execution will populate an object cache for the
; second. The initializer in the cached objects must also be successfully run
; for the test to pass.
