This change makes each unwind step inspect the instruction at the return address and, if needed, read r2 from its saved location and modify the context appropriately. The unwind logic is able to handle both ELFv1 and ELFv2 stacks. Reported by Bug 41050 Patch by Leandro Lupori! Differential Revision: https://reviews.llvm.org/D59694 llvm-svn: 360861
