New C++ versions have deprecated "register" variables and restricted "volatile" semantics, so new gcc's will emit warnings when they see that syntax. Zephyr uses both in our C headers (though we should probably get rid of register and unify with C++'s volatile model), so we're disabling the resulting warnings. But OLD gcc variants (like xcc, sigh) don't understand new -Wvolatile and -Wregister on the command line, so they get confused. Limit the uses to the standard versions for which gcc would emit warnigns; xcc doesn't support those anyway. Signed-off-by: Andy Ross <andyross@google.com> |
