--- Comment #7 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- Created attachment 52023 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52023&action=edit First patch to speed up gfc_itoa() There was a bug in the previous patch (when we write out the low decimal part of a big number, we need to zero-pad). Here is a full patch that bootstraps and regtests, as well as a new test for big integer I/O.
