-==Goal==
-Accurate<sup>1</sup>, crash-free, deadlock-free, low overhead<sup>2</sup> stack unwinding for the SPS profiler for Firefox for Android and Firefox OS.
-<sup>[1]</sup>The correct sequence of code return addresses on the stack, ideally without the unwind terminating before it gets back to main().<br/>
-<sup>[2]</sup>Average unwind cost of 500 microseconds for a 30-frame backtrace on one core of a 1 GHz Cortex A9
-===Scope===
-*Windows and Mac are out of scope for this project.
-*Due to Android and B2G being based on Linux, Linux may be handled by this project as well.
