When typedpointers go away, this assumption will no longer be available - soencode the type of the second operand explicitly and rely on that forthe third.Test case added to demonstrate the backwards compatibility concern,which only comes up when the definition of the second operand comesafter the use (hence the weird basic block sequence) - at which pointthe type needs to be explicitly encoded in the bitcode and the recordlength changes to accommodate this.llvm-svn: 235966 List of files: /llvm-project-15.0.7/llvm/test/Bitcode/cmpxchg.3.6.ll Tue, 28 Apr 2015 04:30:29 +0000 David Blaikie <dblaikie@gmail.com>
