2017-09-26Show the number of VMAs in the tombstone.oreo-mr1-vts-releaseoreo-mr1-devoreo-mr1-cts-devElliott Hughes
Tombstones (especially ones with lots of VMAs) are regularly truncated. We can at least show the number of VMAs, though, for anyone interested in knowing whether they got close to the default 64Ki limit. Bug: http://b/66911122 Bug: 64709603 (presubmit balking at the line above) Test: ran crasher, examined tombstone (cherry picked from commit 868d39a82fb2d9830d253409a1c28f0ae1fcac33) Change-Id: I286db66f28f132307d573dbe5164efc969dc6ddc
2017-07-31Mark the modules as VNDK-SP in Android.bpJustin Yun
As a VNDK-SP module, Android.bp must have 'vndk' tag as well as 'vendor_available: true'. The 'vndk' tag for VNDK-SP formated as follows: vndk: { enabled: true, support_system_process: true, }, VNDK-SP modules will be installed both in system/lib(64) as normal and in system/lib(64)/vndk-sp as a vendor variant. Bug: 63866913 Test: build and boot with BOARD_VNDK_VERSION=current Change-Id: I51fe0859f63ad58b7b91909e7d7d4206443228cd

2017-07-19Cleanup the libbacktrace interface a bit.Christopher Ferris
- Change the field name load_base to load_bias (which is what it really is). - Add a rel_pc field so that callers do not need to compute it themselves. - Remove the BacktraceMap::GetRelativePc() since nobody should need to compute this themselves. Bug: 23762183 Test: Compiles and unit tests pass (debuggerd, libbacktrace). Change-Id: I2cb579767120adf08c407a58f3c487ee3f2b45fc
2017-07-19Speed up StepIfSignalHandler path.Christopher Ferris
The StepIfSignalHandler code reads from the process memory object, which is currently the slowest way to read memory. Change the code to read from the elf memory object which will almost always be a memory mapped file and should be really fast. Also, move the tests for StepIfSignalHandler to its own file. Bug: 23762183 Test: Unit tests pass. Change-Id: I1100b50554e5ef736a87babd484f3f34e9071caa

2017-07-18Add signal handling to the register object.Christopher Ferris
- 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

am: ca94f65ea0 Change-Id: Ic1986a1399a61b9ba3455d7ff4d2365cded86194
2017-07-14Make the library usable as a library.Christopher Ferris
- Add namespace unwindstack everywhere so that it's easier for other code to use the library. - Move some of the header files into include/unwindstack so that they can be exposed. - Modify the headers so that only a limited number need to be exposed. - Update the tools to use the new headers. - Add a GetLoadBias() call on the Elf object. This prevents the need to get the interface object out of the Elf object. - Move the GetRelPc() call out of the Reg class, to the Elf class. It's not always the case that a Reg object will be around when you want to get a relative pc. The tests for this moved to ElfTest.cpp. Bug: 23762183 Test: Unit tests pass.

2017-07-11A few cleanups.Christopher Ferris
- Cleanup the blueprint file a bit. - Fix the formatting in DwarfMemoryTest.cpp. - Fix the misnamed test MemoryBuffer.cpp to MemoryBufferTest.cpp. - Add a function to find the location of the test files so it's not necessary to run the test in the same directory as the test files.
