; This bug has to do with the fact that constant propogation was implemented in
; terms of _logical_ not (! in C) instead of _bitwise_ not (~ in C). This was
; due to a spec change.
; Fix #2: The unary not instruction now no longer exists. Change to xor.
; RUN: llvm-upgrade < %s | llvm-as | opt -constprop | llvm-dis | not grep 'int 0'
