2017-07-28[sanitizer tests CMake] Factor out CMake logic for compiling sanitizer testsGeorge Karpenkov
Currently there's a large amount of CMake logic duplication for compiling sanitizer tests. If we add more sanitizers, the duplication will get even worse. This change factors out common compilation commands into a macro available to all sanitizers. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@309405 91177308-0d34-0410-b5e6-96231b3b80d8

2017-07-28[sanitizers] Sanitizer tests CMake clean up: try #2George Karpenkov
This patch addresses two issues: Most of the time, hacks with `if/else` in order to get support for multi-configuration builds are superfluous. The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it expands to `.` on all single-configuration builds, and to a configuration name otherwise. The `if/else` hacks for the library name generation should also not be done, as CMake has `TARGET_FILE` generator expression precisely for this purpose, as it expands to the exact filename of the resulting target.

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.
