2016-01-27[CMake] Set llvm_tools_dir to LLVM_TOOLS_BINARY_DIR instead of LLVM_TOOLS_DIRAlexey Samsonov
In this way, it should work for both in-LLVM and standalone compiler-rt build. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258991 91177308-0d34-0410-b5e6-96231b3b80d8

2016-01-26[cfi] Exclude __cfi_slowpath_diag from the non-diag rtl.Evgeniy Stepanov
Calls to __cfi_slowpath_diag are only emitted when building with diagnostics, and linking the diag rtl. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258881 91177308-0d34-0410-b5e6-96231b3b80d8
2016-01-26[cfi] Better handling of wild target address.Evgeniy Stepanov
This change enables diagnostics when the target address for a CFI check is out of bounds of any known library, or even not in the limits of the address space. This happens when casting pointers to uninitialized memory. Ubsan code does not yet handle some of these situations correctly, so it is still possible to see a segmentation fault instead of a proper diagnostic message once in a while. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258879 91177308-0d34-0410-b5e6-96231b3b80d8

Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I am the punishment of God...

2016-01-25[cfi] Cross-DSO CFI diagnostic mode (compiler-rt part)Evgeniy Stepanov
* add __cfi_slowpath_diag with a 3rd parameter which is a pointer to the diagnostic info for the ubsan handlers. *__cfi_check gets a 3rd parameter as well. * unify vcall/cast/etc and icall diagnostic info format, and merge the handlers to have a single entry point (actually two points due to abort/noabort variants). * tests Note that this comes with a tiny overhead in the non-diag mode: cfi_slowpath must pass 0 as the 3rd argument to cfi_check. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258744 91177308-0d34-0410-b5e6-96231b3b80d8

2016-01-20[MSan] Clear parameters shadow before invoking malloc/free hooks.Alexey Samsonov
MSan runtime is not itself instrumented, so we need to explicitly clear shadow for function arguments before calling user-provided functions from runtime (e.g. we already do this for several interceptors).

2016-01-16[LSan] Ignore all allocations made inside pthread_create.Alexey Samsonov
Thread stack/TLS may be stored by libpthread for future reuse after thread destruction, and the linked list it's stored in doesn't even hold valid pointers to the objects, the latter are calculated by obscure pointer arithmetic. With this change applied, LSan test suite passes with "use_ld_allocations" flag defaulted to "false". It still requires more testing to check if the default can be switched. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@257975 91177308-0d34-0410-b5e6-96231b3b80d8

2016-01-15[tsan] Store the pointer to ThreadState in TLS slot on Android.Yabin Cui
Summary: 1. Android doesn't support __thread keyword. So allocate ThreadState dynamically and store its pointer in one TLS slot provided by Android. 2. On Android, intercepted functions can be called before ThreadState is initialized. So add test of thr_->is_inited in some places. 3. On Android, intercepted functions can be called after ThreadState is destroyed. So add a fake dead_thread_state to represent all destroyed ThreadStates. And that is also why we don't store the pointer to ThreadState in shadow memory of pthread_self().
