Ref: Bug 1001520 Oh yes, I'd already forgotten that conversation. The GCC documentation is still unclear on that point. In that case, we needed a memory access to a particular location. That happened courtesy of derefencing a volatile pointer set to an absolute address. I think this case might be a little different though as the volatile variable has entirely local scope. No manufactured addresses are involved that could (in principle) be affected by other agents. I wonder if you can use both USED and UNUSED at the same time. Given their intended functions, you should be able to, despite the English meanings implying they are in some way opposites to each other. That would deal with the uncertainty.
