Hello all, I ported Binutils to a 32 bit chip named Score and want to add it to GNU official. I've done the whole process of FSF ASSIGNMENT and already placed the patch on Binutils maillist. But nobody reply till now. GCC patch for Score has been approved by GCC SC. Anybody can tell me why or what should i do? You are appreciate. __________________ Hello Maintainers, Here is a patch to add target Score to GNU Binutils. I volunteer to become the Score port maintainer. Please handle it. ChangeLog: 1.
