Changes: - Remove static assertion on size of a structure, fails on systems where pointers aren't 8 bytes. - Use size_t instead of deducing type of arguments to `nearest_boundary`. Follow-up to D48653. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@336648 91177308-0d34-0410-b5e6-96231b3b80d8
2018-07-10[XRay][compiler-rt] xray::Array Freelist and Iterator UpdatesDean Michael Berris
Summary: We found a bug while working on a benchmark for the profiling mode which manifests as a segmentation fault in the profiling handler's implementation. This change adds unit tests which replicate the issues in isolation. We've tracked this down as a bug in the implementation of the Freelist in the `xray::Array` type. This happens when we trim the array by a number of elements, where we've been incorrectly assigning pointers for the links in the freelist of chunk nodes. We've taken the chance to add more debug-only assertions to the code path and allow us to verify these assumptions in debug builds. In the process, we also took the opportunity to use iterators to implement both `front()` and `back()` which exposes a bug in the iterator decrement operation. In particular, when we decrement past a chunk size boundary, we end up moving too far back and reaching the `SentinelChunk` prematurely. This change unblocks us to allow for contributing the non-crashing version of the benchmarks in the test-suite as well.

Summary: The C interceptors were using `SIZE_T` defined in the interception library as a `__sanitizer::uptr`. On some 32-bit platforms, this lead to the following warning: ``` warning: declaration of ‘void* malloc(SIZE_T)’ conflicts with built-in declaration ‘void* malloc(unsigned int)’ [-Wbuiltin-declaration-mismatch] INTERCEPTOR_ATTRIBUTE void *malloc(SIZE_T size) { ``` `__sanitizer::uptr` is indeed defined as an `unsigned long` on those. So just include `stddef.h` and use `size_t` instead.

build with an IDE (e.g. Xcode) as the generator. Previously the global `USE_FOLDERS` property wasn't set in standalone builds leading to existing settings of FOLDER not being respected.

Now when an Xcode project is generated from a standalone compiler-rt build the project navigator is much less cluttered. The interesting libraries should appear in "Compiler-RT Libraries" in the IDE.

2018-06-26Implement CFI for indirect calls via a member function pointer.Peter Collingbourne
Similarly to CFI on virtual and indirect calls, this implementation tries to use program type information to make the checks as precise as possible. The basic way that it works is as follows, where `C` is the name of the class being defined or the target of a call and the function type is assumed to be `void()`. For virtual calls: - Attach type metadata to the addresses of function pointers in vtables (not the functions themselves) of type `void (B::*)()` for each `B` that is a recursive dynamic base class of `C`, including `C` itself. This type metadata has an annotation that the type is for virtual calls (to distinguish it from the non-virtual case). - At the call site, check that the computed address of the function pointer in the vtable has type `void (C::*)()`. For non-virtual calls: - Attach type metadata to each non-virtual member function whose address can be taken with a member function pointer. The type of a function in class `C` of type `void()` is each of the types `void (B::*)()` where `B` is a most-base class of `C`. A most-base class of `C` is defined as a recursive base class of `C`, including `C` itself, that does not have any bases. - At the call site, check that the function pointer has one of the types `void (B::*)()` where `B` is a most-base class of `C`.

2018-06-18[sanitizer] Guard call to internal_lseek when SANITIZER_MAC is trueFrancis Visoiu Mistrih
r334881 breaks macOS bots because internal_lseek is not defined (neither used on macOS): http://green.lab.llvm.org/green/job/clang-stage1-configure-RA/46240/consoleFull. See discussion from r334881: https://reviews.llvm.org/rL334881 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@334944 91177308-0d34-0410-b5e6-96231b3b80d8
2018-06-18[Fuzzer] Set an explicit libc++ dependency when neededPetr Hosek
On targets that don't link internal libc++ (Fuchsia and Linux) but use libc++ as their C++ library and libFuzzer is being built using the just built compiler together with libc++ as part of runtimes, we need an explicit dependency from libFuzzer object library to libc++ to make sure the headers are available by the time we start building libFuzzer.
