Hi, Joseph, Kito talked to me that he has signed FSF agreement but has not got his svn write access yet. So I help to commit this patch for him (Rev.214405). https://gcc.gnu.org/r214405 I think he needs to finish this form https://sourceware.org/cgi-bin/pdw/ps_form.cgi so that he can commit patches on his own in the future. Could Kito list you as the one who approve his write access request? Or could you suggest someone who may help with it? :) Best regards, jasonwucj > -- > Joseph S. Myers > jos...@codesourcery.com
