It makes any call to getmntent return NULL and it leads to failures on Msan-aarch64{-with-call}-Test/MemorySanitizer.getmntent{_r}.

The latter gives incorrect result since: -4095 -> 0xfffff001 -4096 -> 0xfffff000 (== ~4095) The issue went unnoticed so far because the array alignment caused the last bit not to be set. However, on 32-bit x86 no such alignment is enforced and the wrong page address caused the test to fail. Furthermore, obtain the page size from the system instead of hardcoding 4096.

Both tests presumed that 0x1.p+64 would be converted to 0xFFFFFFFFFFFFFFFFLL, that is the largest value in uint64 range. However, the C/C++ standards do not specify the behavior for converting a floating-point value to an integer of smaller range, and in this case both libgcc and compiler-rt implementations return 0 instead. Since the current behavior is correct with regards to standards and there is no good way of expressing 0xFFFFFFFFFFFFFFFFLL in single- or double-precision float, I've removed the failing test altogether.

FreeBSD and macOS do not have the `mallinfo` and `mallopt` functions, so normally these tests would fail, but when sanitizers are enabled, they incorrectly succeed, because the sanitizers define interceptors for these functions. This also applies to some other malloc-related functions, such as `memalign`, `pvalloc` and `cfree`. Fix this by not intercepting `mallinfo`, `mallopt`, `memalign`, `pvalloc` and `cfree` for FreeBSD and macOS, in all sanitizers. Also delete the non-functional `cfree` wrapper for Windows, to fix the test cases on that platform.

| | | | | | | | | | | | | | | | | | Summary: Repoisoning just the minimal redzones might leave an unpoisoned gap of the size of the actual redzone minus minimal redzone size. After ASan activation the actual redzone might be bigger than the minimal size and ASan allocator assumes that the chunk returned by the common allocator is either entirely poisoned or entirely not poisoned (it's too expensive to check the entire chunk or always poison one).

* builtins: support building ARM builtins for a HF targetSaleem Abdulrasool2017-01-1135-7/+179
| | | | | | | | | | | | | | The `-target` impacts the CC for the builtins. HF targets (with either floating point ABI) always use AAPCS VFP for the builtins unless they are AEABI builtins, in which case they use AAPCS. Non-HF targets (with either floating point ABI) always use AAPCS for the builtins and AAPCS for the AEABI builtins. This introduces the thunks necessary to switch CC for the floating point operations. This is not currently enabled, and should be dependent on the target being used to build compiler-rt. However, as a stop-gap, a define can be added for ASFLAGS to get the thunks. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@291677 91177308-0d34-0410-b5e6-96231b3b80d8

* [tsan] Implement a 'ignore_noninstrumented_modules' flag to better suppress ↵Kuba Mracek2017-01-116-45/+153
| | | | | | | | | | | | | | | | false positive races On Darwin, we currently use 'ignore_interceptors_accesses', which is a heavy-weight solution that simply turns of race detection in all interceptors. This was done to suppress false positives coming from system libraries (non-instrumented code), but it also silences a lot of real races. This patch implements an alternative approach that should allow us to enable interceptors and report races coming from them, but only if they are called directly from instrumented code. The patch matches the caller PC in each interceptors. For non-instrumented code, we call ThreadIgnoreBegin. The assumption here is that the number of instrumented modules is low. Most likely there's only one (the instrumented main executable) and all the other modules are system libraries (non-instrumented).

* [scudo] Separate hardware CRC32 routinesKostya Kortchinsky2017-01-107-34/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: As raised in D28304, enabling SSE 4.2 for the whole Scudo tree leads to the emission of SSE 4.2 instructions everywhere, while the runtime checks only applied to the CRC32 computing function. This patch separates the CRC32 function taking advantage of the hardware into its own file, and only enabled -msse4.2 for that file, if detected to be supported by the compiler. Another consequence of removing SSE4.2 globally is realizing that memcpy were not being optimized, which turned out to be due to the -fno-builtin in SANITIZER_COMMON_CFLAGS. So we now explicitely enable builtins for Scudo. The resulting assembly looks good, with some CALLs are introduced instead of the CRC32 code being inlined.

* tsan: Introducing a function to flush the shadow memory from third-party ↵Dmitry Vyukov2017-01-073-0/+7
| | | | | | | | | | | | | | libraries As discussed with Dmitry (https://goo.gl/SA4izd), I would like to introduce a function to be called from a third-party library to flush the shadow memory. In particular, we ran some experiments with our tool Archer (an OpenMP data race detector based on Tsan, https://github.com/PRUNER/archer) and flushing the memory at the end of an outer parallel region, slightly increase the runtime overhead, but reduce the memory overhead of about 30%. This feature would come very handy in case of very large OpenMP applications that may cause an "out of memory" exception when checked with Tsan.

* Enable weak hooks on darwinFrancis Ricci2017-01-079-1/+42
| | | | | | | | | | | | | | | | Summary: By default, darwin requires a definition for weak interface functions at link time. Adding the '-U' link flag with each weak function allows these weak interface functions to be used without definitions, which mirrors behavior on linux and windows.

| | | | | | | | | | | | Darwin This patch add a new sanitizer flag, print_module_map, which enables printing a module map when the process exits, or after each report (for TSan). The output format is very similar to what Crash Reporter produces on Darwin (e.g. the format of module UUIDs). This enables users to use the existing symbol servers to offline symbolicate and aggregate reports.

| | | | | | | | | | | | | | | | Implement the missing __floattitf() and __floatuntitf() functions, to convert 128-bit (unsigned) integers to quad-precision floating-point types. This is needed e.g. on AArch64 where 'long double' is a quad-precision type. The code is based on the existing code for __floattixf() and __floatuntixf(), updated to account for different bit field lengths of quad-precision float. The tests are also copied, with the rounding tests adjusted for longer significand.

* [cmake] Disable appending -msse4.2 flag implicitlyMichal Gorny2017-01-062-2/+0
| | | | | | | | | | | | | | | | | | | | | | | Disable the code appending -msse4.2 flag implicitly when the compiler supports it. The compiler support for this flags do not indicate that the underlying CPU will support SSE4.2, and passing it may result in SSE4.2 code being emitted *implicitly*. If the target platform supports SSE4.2 appropriately, the relevant bits should be already enabled via -march= or equivalent. In this case passing -msse4.2 is redundant. If a runtime detection is desired (which seems to be a case with SCUDO), then (as gcc manpage points out) the specific SSE4.2 needs to be isolated into a separate file, the -msse4.2 flag can be forced only for that file and the function defined in that file can only be called when the CPU is determined to support SSE4.2. This fixes SIGILL on SCUDO when it is compiled using gcc-5.4.
