test/ELF/lto/arm-wrap-personality.ll

;; Wrapped symbols are marked as weak for LTO to inhibit IPO. The ARM backend
;; was previously explicitly marking the personality function as global, so if
;; we attempted to wrap the personality function, its initial binding would be
;; weak and then the ARM backend would attempt to change it to global, causing
;; an error. Verify that the ARM backend no longer does this and we can
;; successfully wrap the personality symbol.
