Hi：
This has nothing to do with the architecture implementation. The variable r in
your code were indeed not defined, and then `-Werror -Wextra` was added during
compilation. `-Wextra` enables `-Wuninitialized`, which is described as
follows:
`Warn if an object with automatic or allocated storage duration is used without
having been initialized. `
