Martin Storsjo	44266b9e11	[PPC64][libunwind] Fix r2 not properly restored ... 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!

Jonathan Roelofs	6e50d93afc	Add a test harness ... Mostly cargo-culted from libcxxabi, since the unwinder was forked from there in the first place. There may still be cruft that's only applicable to libcxxabi, but that can be addressed in-tree. https://reviews.llvm.org/D35038 llvm-svn: 307266	2017-07-06 15:20:12 +00:00
