New Revision: 307266
URL: http://llvm.org/viewvc/llvm-project?rev=307266&view=rev
Log:
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.
