Bug ID: 16564
Summary: _Unwind_GetIP not provided on ARM
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Headers
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
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:
http://llvm.org/viewvc/llvm-project?view=revision&revision=148469
Our current workaround uses _Unwind_VRS_Get() and removing the thumb mode bit:
http://src.chromium.org/viewvc/chrome/trunk/src/base/debug/stack_trace_android.cc?revision=210132#l41
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?
