[PATCH, ARM] Don't pull in unwinder for 64-bit division routines

2012-07-20 Thread Julian Brown
Hi, This (old!) patch avoids uselessly pulling in the unwinder for 64-bit division routines. I last posted it here: http://gcc.gnu.org/ml/gcc-patches/2009-10/msg01618.html Other people have noticed the same issue, e.g.: http://gcc.gnu.org/ml/gcc-help/2011-03/msg00187.html Note that we take spe
