| | | | | | | | When doing a local unwind, do not include the frames that come from either libunwind or libbacktrace. Bug: 11518609 Change-Id: I0ec8d823aebbfa0903e61b16b7e5663f3fd65e78

| * Refactor the code.Christopher Ferris2015-03-3122-758/+761
| | | | | | | | | | | | | | | | The object hierarchy was confusing and convoluted. This removes a lot of unnecessary code, and consolidates the BacktraceCurrent and BacktraceThread code into BacktraceCurrent. Change-Id: I01c8407d493712a48169df49dd3ff46db4a7c3ae

| * Add -Wno-inline-asm to Clang flags.Stephen Hines2015-03-312-0/+7
| | | | | | | | | | | | | | | | The latest clang (r230699) does not allow SP/PC to be declared in inline asm lists. This is a problem for libraries that are attempting to save all register state. Change-Id: I1ce80530f8be85fd74e949d0c65b60080e0aaf2a

| | | | | | | | | | Included tests for this new feature. Changed the NULLs to nullptr in backtrace_test. Changed UniquePtr to std::unique_ptr in backtrace_test. Change-Id: I92375465b8f8ba84589834cc162db5915bf1be81
* Move map data into backtrace data proper.Christopher Ferris2015-02-068-32/+46
| | | | | | | | | | | The backtrace structure used to include a pointer to a backtrace_map_t that represented the map data for a particular pc. This introduced a race condition where the pointer could be discarded, but the backtrace structure still contained a pointer to garbage memory. Now all of the map information is right in the structure. Bug: 19028453 Change-Id: If7088a73f3c6bf1f3bc8cdd2bb4b62e7cab831c0

| * Only copy mcontext data from sigcontext.Christopher Ferris2014-05-232-5/+9
| | | | | | | | | | | | | | | | | | | | The ucontext_t data structure could be bigger than the kernel data structure. Since the unwinder only cares about the mcontext data, only copy that out of the structure. The mcontext data is the same size in the kernel and in the ucontext_t structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new version doesn't require any specialized thread implementation, it uses the Current implementation to do its job. In addition, it runs much faster when multiple threads are trying to unwind at the same time since the global signal lock is held for only a small amount of time. Even running through the threads one at a time should be faster since it no longer requires two passes through the unwound stacks. The new code now allows multiple simultaneous unwinds of the same thread. Finally, add the ability to unwind from a ucontext_t passed in. This functionality doesn't work for remote unwinds yet.
