* [Sanitizer] Make StackTrace::Unwind the only public way to unwind a stack trace.Alexey Samsonov2013-11-07
| | | | git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194196 91177308-0d34-0410-b5e6-96231b3b80d8
* tsan: move shadow stack from thread descriptors to fixed addressesDmitry Vyukov2013-10-16
| | | | | | | | | | This allows to increase max shadow stack size to 64K, and reliably catch shadow stack overflows instead of silently corrupting memory. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@192797 91177308-0d34-0410-b5e6-96231b3b80d8
