- Add the StepIfSignalHandler function to the Regs object that checks if the code is in a signal handler. - Add tests for new code, also add a test that unwinds through a signal handler. - Slight modification to Elf to fail if a bad machine type is encountered. Add tests for this. Bug: 23762183 Test: Ran unit tests. Change-Id: Idafa1105d00b91a9343d7464ac9ed1cb95830963
