llvm-6502/test/Transforms/ConstProp/2002-05-03-NotOperator.ll

; 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-as < %s | opt -constprop | llvm-dis | not grep 'int 0'
