; This testcase is primarily used for testing that global values can be used as
; constant pointer initializers. This is tricky because they can be forward
; declared and involves an icky bytecode encoding. There is no meaningful
; optimization that can be performed on this file, it is just here to test
; assembly and disassembly.
