From: Mike Beaton <mjsbea...@gmail.com> This warning was already disabled in CLANGDWARF by commit d3225577123767fd09c91201d27e9c91663ae132.
gcc can distinguish between optimised-away variable usage (as can occur in valid debug code) and genuinely unused variables, and only complains about the latter. clang cannot, and therefore this warning ends up complaining about valid debug code under clang. Since EDK-II code is in general going to be compiled by gcc as well as clang then disabling this warning in clang does not amount to entirely removing potentially valid warnings about genuinely unused variables.
