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

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).
