2017-04-26[asan] Add support for running lit tests in the iOS SimulatorKuba Mracek
This patch adds a basic support for running the ASan lit test suite against an iOS Simulator. This is done by generating more lit.site.cfg configurations into subdirectories such as IOSSimI386Config and IOSSimX86_64Config. These test suites are not added into "check-all" or into "check-asan", they have to be run manually.

2017-03-22[compiler-rt] build compiler-rt runtimes without LTOBob Haarman
Summary: Currently, we build the compiler-rt runtimes with link-time optimization if LTO is configured for the LLVM project. This will break external programs that don't invoke the linker in such a way that it supports LLVM's LTO. To avoid this, this change causes the compiler-rt runtimes to be compiled with -fno-lto. This also makes the check-profile tests work on systems when doing a lld LTO build on a system where the system linker does not support LLVM LTO.

2017-03-21[compiler-rt] respect CMAKE_EXE_LINKER_FLAGS in compiler and library testsBob Haarman
Summary: check_cxx_compiler_flag and check_library_exists could fail because they ignored CMAKE_EXE_LINKER_FLAGS and therefore would always fail to produce executables. Cmake policy CMP0056 fixes this, but was explicitly set to OLD in our CMakeLists because it caused problems with test_target_arch. This change sets the policy to NEW to fix the problem with the compiler and library tests, and temporarily clears CMAKE_EXE_LINKER_FLAGS inside test_target_arch to emulate the old behavior there. This allows, for example, LTO builds that require lld to succeed.

2017-01-23[lsan] Enable LSan for x86 Linux.Maxim Ostapenko
People keep asking LSan to be available on 32 bit targets (e.g. https://github.com/google/sanitizers/issues/403) despite the fact that false negative ratio might be huge (up to 85%). This happens for big real world applications that may contain random binary data (e.g. browser), but for smaller apps situation is not so terrible and LSan still might be useful. This patch adds initial support for x86 Linux (disabled by default), ARM32 is in TODO list. We used this patch (well, ported to GCC) on our 32 bit mobile emulators and it worked pretty fine thus I'm posting it here to initiate further discussion.

2017-01-18[scudo] Refactor of CRC32 and ARM runtime CRC32 detectionKostya Kortchinsky
Summary: ARM & AArch64 runtime detection for hardware support of CRC32 has been added via check of the AT_HWVAL auxiliary vector. Following Michal's suggestions in D28417, the CRC32 code has been further changed and looks better now. When compiled with full relro (which is strongly suggested to benefit from additional hardening), the weak symbol for computeHardwareCRC32 is read-only and the assembly generated is fairly clean and straight forward. As suggested, an additional optimization is to skip the runtime check if SSE 4.2 has been enabled globally, as opposed to only for scudo_crc32.cpp. scudo_crc32.h has no purpose anymore and was removed.

2017-01-10[scudo] Separate hardware CRC32 routinesKostya Kortchinsky
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.

2017-01-06[cmake] Disable appending -msse4.2 flag implicitlyMichal Gorny
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.

2016-12-05[compiler-rt] Remove duplicates from COMPILER_RT_SUPPORTED_ARCHKuba Mracek
Since we’re adding an entry into COMPILER_RT_SUPPORTED_ARCH for all architectures of all Darwin platforms, COMPILER_RT_SUPPORTED_ARCH often ends up having duplicate items. Let’s remove them.

2016-11-30[scudo] 32-bit and hardware agnostic supportKostya Kortchinsky
Summary: This update introduces i386 support for the Scudo Hardened Allocator, and offers software alternatives for functions that used to require hardware specific instruction sets. This should make porting to new architectures easier. Among the changes: - The chunk header has been changed to accomodate the size limitations encountered on 32-bit architectures. We now fit everything in 64-bit. This was achieved by storing the amount of unused bytes in an allocation rather than the size itself, as one can be deduced from the other with the help of the GetActuallyAllocatedSize function. As it turns out, this header can be used for both 64 and 32 bit, and as such we dropped the requirement for the 128-bit compare and exchange instruction support (cmpxchg16b). - Add 32-bit support for the checksum and the PRNG functions: if the SSE 4.2 instruction set is supported, use the 32-bit CRC32 instruction, and in the XorShift128, use a 32-bit based state instead of 64-bit. - Add software support for CRC32: if SSE 4.2 is not supported, fallback on a software implementation. - Modify tests that were not 32-bit compliant, and expand them to cover more allocation and alignment sizes. The random shuffle test has been deactivated for linux-i386 & linux-i686 as the 32-bit sanitizer allocator doesn't currently randomize chunks.

2016-11-29[sanitizer] Add macOS minimum deployment target to all compiler invocations ↵Kuba Mracek
in lit tests The Clang driver on macOS decides the deployment target based on various things, like your host OS version, the SDK version and some environment variables, which makes lit tests pass or fail based on your environment. Let's make sure we run all lit tests with `-mmacosx-version-min=${SANITIZER_MIN_OSX_VERSION}` (10.9 unless overriden).
