From df2906186b6952c57b1f662bfef0b65c9f8c2e0d Mon Sep 17 00:00:00 2001 From: Christopher Ferris Date: Wed, 22 Jan 2014 19:21:07 -0800 Subject: Re-enable libunwind for arm. Update to handle the new optimized way that libunwind works. In addition, a small refactor of the BacktraceMap code. A few new tests of for good measure.
