For the compressed\n  sections, the load bias was not the same as the data from the uncompressed\n  section.\n- Move the initialization of the compressed section into Init. It was too easy\n  to forget to call the init of the compressed section.\n- Do not automatically add in load bias to the pc before calling ElfInterface\n  code. Do all of the pc manipulations in the Elf object.\n- Change the interface GetFunctionName code to pass in the load_bias instead\n  of modifying the pc inside the code.\n- Modify the Step function to pass in the elf offset, not add it to the pc.\n  It is necessary to have two different relative values when executing the\n  Step: a pc that is relative to the beginning of the elf for the reading data\n  the actual instructions when trying to determine if this is in a signal\n  frame, and a pc that is relative to the map for finding the appropriate\n  unwind information.\n- Add a feature to Unwinder so that an unwind can be stopped if it ends up\n  in map that has a specified suffix. This is so that the ART unwinding\n  code doesn\u0027t require skipping the compressed section. Instead, stop at\n  if trying to unwind through a known suffix code that means the code is\n  in java code. This is important because the compressed section data is\n  not only used by the jave compiled code, so that will continue to work.\n- Fix tests for restructuring, add new tests for new functionality.\n\nTest: Ran art test 137-cfi using new unwinder as default.\nTest: Ran new unit tests.\nChange-Id: I42e658c64c5e14f698ba34944a3043afac967884\n"
