The former is simply wrong -- the code will either never be used or will always be used, rather than being dependent upon whether it's built with debug assertions enabled. The macro DEBUG isn't ever set by the llvm build system. But, the macro DEBUG(X) is defined (unconditionally) if you happen to include llvm/Support/Debug.h. The code in Value.h which was erroneously protected by the #ifdef DEBUG didn't even compile -- you can't cast<> from an LLVMOpaqueValue directly. Fortunately, it was never invoked, as Core.cpp included Value.h before Debug.h. The conditionalized code in AArch64CollectLOH.cpp was previously always used, as it includes Debug.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@280056 91177308-0d34-0410-b5e6-96231b3b80d8
