; 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.
