From: Giulio Benetti Date: Mon, 3 May 2021 11:13:44 +0000 (+0200) Subject: package/gcc: add upstream patches that introduce -mcmodel=large option for or1k X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f8367664f8aea1e962c111df0432014d744fd00f;p=buildroot.git package/gcc: add upstream patches that introduce -mcmodel=large option for or1k Let's add upstream patches introducing -mcmodel=large or1k gcc option that works in conjunction with previous binutils patch. That option fix binutils bug 21464[1] allowing to build libgeos with no problem. This way we can consider buildroot toolchain binutils bug 21464 free.
