Even though we already treat all vector types as equivalent to 'char', we were using field-offset information for them with TBAA, and this renders undefined the intra-value indexing we intend to allow. Note that, although 'char' is universally aliasing, with path TBAA, we can still differentiate between access to s.a and s.b in struct { char a, b; } s;. We can't use this capability as-is for vector types.

This causes the builtin atomic functions (e.g.: __atomic_fetch_add) to not generate thread-safe assembly for these operations, which breaks our firmware. We target bare metal, and need to atomically modify variables in our interrupt routines, and task threads. Internally, the -mthread-model flag determines whether to lower or expand atomic operations (see D4984). This change removes the overridden thread model methods, and instead relies on the base ToolChain class to validate the thread model (which already includes logic to validate single thread model support). If the single thread model is required, the -mthread-model flag will have to be provided. As a workaround "-mthread-model posix" could be provided, but it only works due to a bug in the validation of the -mthread-model flag (separate patch coming to fix this). https://reviews.llvm.org/D37493 Patch by: Ian Tessier! ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_50@314464 91177308-0d34-0410-b5e6-96231b3b80d8

This is provided on a best-effort basis; right now, this can be used to undo the ABI change in r310401, reverting Clang to its prior C++ ABI for pass/return by value of class types affected by that change, and to undo the ABI change in r262688, reverting Clang to using integer registers rather than SSE registers for passing <1 x long long> vectors. The intent is that we will maintain this backwards compatibility path as we make ABI-breaking fixes in future. The reversion to the old behavior for r310401 is also applied to the PS4 target since that change is not part of its platform ABI (which is essentially to do whatever Clang 3.2 did). ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_50@312013 91177308-0d34-0410-b5e6-96231b3b80d8

Do not sanitize the 'this' pointer of a member call operator for a lambda with no capture-default, since that call operator can legitimately be called with a null this pointer from the static invoker function. Any actual call with a null this pointer should still be caught in the caller (if it is being sanitized).

This fixes ABI differences between Clang and GCC: * Previously, Clang ignored the move constructor when making this determination. It now takes the move constructor into account, per https://github.com/itanium-cxx-abi/cxx-abi/pull/17 (this change may seem recent, but the ABI change was agreed on the Itanium C++ ABI list a long time ago). * Previously, Clang's behavior when the copy constructor was deleted was unstable -- depending on whether the lazy declaration of the copy constructor had been triggered, you might get different behavior. We now eagerly declare the copy constructor whenever its deletedness is unclear, and ignore deleted copy/move constructors when looking for a trivial such constructor. This also fixes an ABI difference between Clang and MSVC: * If the copy constructor would be implicitly deleted (but has not been lazily declared yet), for instance because the class has an rvalue reference member, we would pass it directly. We now pass such a class indirectly, matching MSVC. Based on a patch by Vassil Vassilev, which was based on a patch by Bernd Schmidt, which was based on a patch by Reid Kleckner!

The assert being discussed is assert(!B.lookup(R, BindingKey::Direct)) in lib/StaticAnalyzer/Core/RegionStore.cpp, however the root cause is different. For classes with empty bases the offsets might be tricky. For example, let's assume we have struct S: NonEmptyBase, EmptyBase { ... }; In this case Clang applies empty base class optimization and the offset of EmptyBase will be 0, it can be verified via clang -cc1 -x c++ -v -fdump-record-layouts main.cpp -emit-llvm -o /dev/null. When the analyzer tries to perform zero initialization of EmptyBase it will hit the assert because that region has already been "written" by the constructor of NonEmptyBase.
