commit d07eadaa366fa34065a6b815b6863371ca8fa9bf Author: Stefan Reinauer reinauer@chromium.org Date: Tue Sep 10 11:02:58 2013 -0700
armv7: mark EABI compatibility symbols as used
These symbols are not used anywhere in our C code, so when using GCC's link time optimization feature they will be dropped even though they're needed by libgcc. Hence we need to mark them as used so GCC does not stumble and fall over its own guts.
