<pre>I'm writing stack trace dumping code and noticed clang doesn't provide
_Unwind_GetIP on ARM in its implementation of unwind.h
For reference, I believe the ARM code was added in r148469 by eugenis@ but
_Unwind_GetIP was left out:
<a href="http://llvm.org/viewvc/llvm-project?view=revision&revision=148469">http://llvm.org/viewvc/llvm-project?view=revision&revision=148469</a>
Our current workaround uses _Unwind_VRS_Get() and removing the thumb mode bit:
<a href="http://src.chromium.org/viewvc/chrome/trunk/src/base/debug/stack_trace_android.cc?revision=210132#l41">http://src.chromium.org/viewvc/chrome/trunk/src/base/debug/stack_trace_android.cc?revision=210132#l41</a>
Apologies in advance as I'm new to filing llvm bugs... but if GCC's ARM
unwind.h provides an _Unwind_GetIP, should clang provide an implementation as
well?</pre>
