2017-12-28-fsanitize=vptr warnings on bad static types in dynamic_cast and typeidStephan Bergmann
...when such an operation is done on an object during con-/destruction. (This adds a test case to compiler-rt/test/ubsan/TestCases/TypeCheck/vptr.cpp that, unlike the existing test cases there, wants to detect multiple UBSan warnings in one go. Therefore, that file had to be changed from globally using -fno-sanitize-recover to individually using halt_on_error only where appropriate.) This is the compiler-rt part of a patch covering both cfe and compiler-rt.

2017-09-15ubsan: Unbreak ubsan_cxx runtime library on Windows.Peter Collingbourne
This was originally broken by r258744 which introduced a weak reference from ubsan to ubsan_cxx. This reference does not work directly on Windows because COFF has no direct concept of weak symbols. The fix is to use /alternatename to create a weak external reference to ubsan_cxx. Also fix the definition (and the name, so that we drop cached values) of the cmake flag that controls whether to build ubsan_cxx. Now the user-controllable flag is always on, and we turn it off internally depending on whether we support building it.

2016-10-26[ubsan] Fix vptr.cpp test to be more resilient. NFC.Robert Lougher
The test contains a switch statement in which two of the cases are tail-merged, with the call to __ubsan_handle_dynamic_type_cache_miss_abort in the common tail. When tail-merging occurs, the debug location of the tail is randomly taken from one of the merge inputs. Luckily for the test, the expected line number in the check is the one which is chosen by the tail-merge. However, if the switch cases are re-ordered the test will fail. This patch disables tail-merge, making the test resilient to changes in tail-merge, and unblocking review D25742. It does not change the semantics of the test. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@285208 91177308-0d34-0410-b5e6-96231b3b80d8

2015-02-20[Sanitizer] Refactor SuppressionContext class.Alexey Samsonov
SuppressionContext is no longer a singleton, shared by all sanitizers, but a regular class. Each of ASan, LSan, UBSan and TSan now have their own SuppressionContext, which only parses suppressions specific to that sanitizer. "suppressions" flag is moved away from common flags into tool-specific flags, so the user now may pass ASAN_OPTIONS=suppressions=asan_supp.txt LSAN_OPIONS=suppressions=lsan_supp.txt in a single invocation. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@230026 91177308-0d34-0410-b5e6-96231b3b80d8

2014-11-06UBSan: Teach isDerivedFromAtOffset and findBaseAtOffset about vbasesDavid Majnemer
When the __virtual_mask is set, __offset_flags >> __offset_shift yields an offset into the vtable. Dereferencing this vtable slot gets us the vbase offset.
