Summary: Since the personality functions do the actual unwinding on ARM, and will also stop unwinding when they encounter a handler, we invoke _Unwind_VRS_Interpret() directly form _Unwind_Backtrace(). To simplify, the logic for decoding an EHT is moved out of unwindOneFrame() and into its own function, decode_eht_entry(). Unlike unwindOneFrame(), which could only handle ARM's compact personality function entries (section 6.3) decode_eht_entry() can handle the generic entries (section 6.2).

2014-08-29Revert "Fix _Unwind_Backtrace for arm."Dan Albert
Reverting because there is a more complete fix available upstream (one that can fully unwind in the presence of generic EHT entries). This reverts commit 0edf7c5360403441c060618014887e9a723fe423. Bug: 16874447 Change-Id: I5aa38183237865187156a8d8a050fd09a04ef109

The unwind code does not properly update the IP when on arm. There is still a bug in this unwinding code, it stops unwinding at the first catch it finds. Bug: 16874447 Change-Id: I40a4d8990246dccad18612c7291d00293266d9bc
2014-08-19Improve logging of aborts for Android.Dan Albert
In Android, stderr only goes to the console, and as such will only ever be seen by adb shell users. Since very few developers will ever actually see that, also send the abort message to logcat and the tombstone. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@215983 91177308-0d34-0410-b5e6-96231b3b80d8 Bug: 17059126 Change-Id: I67055243d0750b1ea3cf5c77e911353cc9905878 (cherry picked from commit f02f3d37e0309314ce69f9bf49f17f54bed2c109)

2014-07-02Add support for the ARM EHABI unwinder.Dan Albert
Only use the LLVM unwinder for ARM. The LLVM unwinder now supports ARM EHABI, so we can finally use that for exception handling on ARM. The unwinder doesn't work for other architectures though (aside from on Darwin), so use libunwind for now. Change-Id: Ife8b0b33dbfe96c10eab102cd36d30149d68ace9

Fix demangling crasher. The crasher involved nested <encoding> involving parameter packs, which exposed a logic bug causing an empty vector<string> to be accessed with back(). In addition to fixing the bug, I've inserted numerous preemptive checks for similar bugs in the hopes that if another bug is uncovered, the bug results in an invalid mangled string instead of a demangler crash. Test suite updated with string that was causing the crash. Rename UnwindRegisters*.s files to UnwindRegisters*.S, step 2 of 2 Rename UnwindRegisters*.s files to UnwindRegisters*.S, step 1 of 2 ...
