* Re-enable libunwind for arm.Christopher Ferris2014-01-281-6/+47
| | | | | | | | | | 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. Change-Id: I2f9b4f5ad5a0dfe907b31febee76e4b9b94fb76f
* Rewrite libbacktrace to be all C++.Christopher Ferris2014-01-161-38/+57
| | | | | | | | | | | | | This includes removing the map_info.c source and replacing it with the BacktraceMap class to handle all map related code. Change all callers of libbacktrace map functionality. Also modify the corkscrew thread code so that it doesn't need to build the map twice (once in the corkscrew format and once in the libbacktrace format). Change-Id: I32865a39f83a3dd6f958fc03c2759ba47d12382e
* Next phase of the move, reformat use C++ features.Christopher Ferris2014-01-131-179/+147
| | | | | | | | | | | | | | | | | Use the libbacktrace C++ interface instead of the C interface in debuggerd. Reformat the debuggerd code to be closer to Google C++ style. Fix all debuggerd casts to be C++ casts. Add a frame number to the frame data structure for ease of formatting and add another FormatFrameData function. Change the format_test to use the new FormatFrameData function. Modify all of the backtrace_test to use the C++ interface. Change-Id: I10e1610861acf7f4a3ad53276b74971cfbfda464
* Move BACKTRACE_NO_TID to BACKTRACE_CURRENT_THREAD.Christopher Ferris2014-01-091-12/+19
| | | | | | | | | | | Use a bit better name for this. The other name was a bit confusing. Change-Id: I1261f2ee3854a9c8b82133ad0bfbbbe48b43c9ac (cherry picked from commit 242b1a8c7a5ec73172bac811e51acbc27201f22c) Conflicts: libbacktrace/Backtrace.cpp
* Use new defines in test code.Christopher Ferris2013-11-051-13/+13
| | | | | | | In addition, fix up the warnings and remove the -fpermissive when compiling. Change-Id: Ia27b902499b34ff3d881acb9057120af390baf2c
* Rewrite libbacktrace using C++.Christopher Ferris2013-10-281-0/+660
The old code was essentially trying to be C++ in C and was awkward. This change makes it all objects with a thin layer that C code can use. There is a C++ backtrace object that is not very useful, this code will replace it. This change also includes moving the backtrace test to a gtest, and adding coverage of all major functionality.
