;; Ensure no regression on ARM/gcc compatibility for 
;; emitting explicit symbol relocs for nonexternal symbols 
;; versus section symbol relocs (with offset) - 
;;
;; Default llvm behavior is to emit as section symbol relocs nearly
;; everything that is not an undefined external. Unfortunately, this 
;; diverges from what codesourcery ARM/gcc does!

;; Tests that reloc to _MergedGlobals show up as explicit symbol reloc
