Patch merged into coreboot/master: Only apply libgcc workaround on x86-32
by gerrit＠coreboot.org 09 Aug '15

09 Aug '15

the following patch was just integrated into master: commit 1fa52740713a77a58aa038f61cc0e5ab6112a896 Author: Stefan Reinauer <reinauer(a)chromium.org> Date: Fri Jul 31 17:56:03 2015 -0700 Only apply libgcc workaround on x86-32 This should probably be moved out of lib and to arch/x86, since it does not even apply on x86-64, and ARM has its own copy of libgcc.

the following patch was just integrated into master: commit d146ac6a33a9ba578c7dce0abf8b4ca65689b425 Author: Stefan Reinauer <reinauer(a)chromium.org> Date: Fri Jul 31 13:50:03 2015 -0700 Move function/data sections to common CFLAGS Instead of adding -ffunction-sections and -fdata-sections to every architecture, just add it to CFLAGS_common, thus making sure that new architectures will pick it up automatically.
