File libgcc.patch of Package grub2.14589
From: Paulo Flabiano Smorigo <pfsmorigo@linux.vnet.ibm.com> Date: Wed, 13 Aug 2014 19:00:19 +0000 Subject: [PATCH 142/143] Files reorganization and include some libgcc fuctions As we avoid libgcc dependency for powerpc64el, we moved some functions to other files and add the necessary ones. * Makefile.core.def: Include compiler-rt.S. * misc.c: Add the necessary libgcc functions. * compiler-rt.S: New file. * libgcc.h: Move some content from here ... * compiler.h: ... to here.
