the following is the output for ./gcc —help=common:
  -flive-patching             Same as -flive-patching=.  Use the latter option
                              instead.
  -flive-patching=[inline-only-static|inline-clone] Control IPA optimizations
                              to provide a safe compilation for live-patching.
                              At the same time, provides multiple-level control
                              on the enabled IPA optimizations.
 
Not sure what’s you mean of “the line is too long”? could you please specify the above which line?

I have used contrib/check_GNU_style.sh to check the patch, I did see one place that complains about 2 spaces in between sentences, fixed it.
but I didn’t see spaces + tabs mix issue with the script. could you please specify?

thanks.
