* Merging r310983:Hans Wennborg2017-08-211-33/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ------------------------------------------------------------------------ r310983 | rsmith | 2017-08-15 18:49:53 -0700 (Tue, 15 Aug 2017) | 31 lines PR19668, PR23034: Fix handling of move constructors and deleted copy constructors when deciding whether classes should be passed indirectly. 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! This is a re-commit of r310401, which was reverted in r310464 due to ARM failures (which should now be fixed). ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_50@311410 91177308-0d34-0410-b5e6-96231b3b80d8

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.

| | | | | | | | | | | | | | | | | Add support to the retain-count checker for an annotation indicating that a function's implementation should be trusted by the retain count checker. Functions with these attributes will not be inlined and the arguments will be treating as escaping. Adding this annotation avoids spurious diagnostics when the implementation of a reference counting operation is visible but the analyzer can't reason precisely about the ref count.

Therefore if the alloca addr space is non-zero and it needs to be casted to default address space, the cast needs to be inserted in the same BB as the alloca insted of the current builder insert point since the current insert point may be in a different BB.
