* [compiler-rt][builtins][sanitizers] Update compiler-rt test cases forAmy Kwan2019-04-301-6/+8
| | | | | | | | | | | | | | | | compatibility with system's toolchain This patch aims to: - Guard ompiler-rt/test/builtins/Unit/compiler_rt_logb_test.c with macros, so the test runs on GLIBC versions >= 2.23. This is because the test relies on comparing its computed values to libm. Oolder versions might not compute to the same value as the compiler-rt value. - Update compiler-rt/test/sanitizer_common/TestCases/Posix/getpw_getgr.cc so that std::string is not used, since false positives may be detected.

* [compiler-rt] Intercept the bcmp() function.Clement Courbet2019-02-261-1/+11
| | | | | | | | | | | | | | | | | | | | | Summary: I have not introduced a separate hook for `bcmp()` as I don't think there should be any reason for a sanitizer to treat it differently from `memcmp()`. This is only enabled when building on POSIX with GNU extensions. Context: this is to avoid losing coverage when emitting `bcmp() == 0` instead of `memcmp() == 0` in llvm, see https://reviews.llvm.org/D56593.

* Fix sanitizer tool list used to generate sanitizer_common tests to be ↵Dan Liew2019-01-162-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | up-to-date. Summary: This replaces the sanitizer tool list (used for generating sanitizer_common configurations) with a tool list derived from existing build system information. Previously sanitizer_common had its own list of supported sanitizer tools. This was bad because it was out of sync with the rest of the build system. Notably it meant that the sanitizer_common runtime was only being tested on Darwin the ASan dylib and not the other sanitizer dylibs that are built for Darwin (LSan, TSan, and UBSan). Unfortunately enabling the tests against other sanitizer dylibs has lead to some test failures on Darwin. For now they've been marked as XFAIL until the failures can investigated properly. For Windows and Android we use the old sanitizer tool list to try avoid bot breakages. rdar://problem/47143078 Reviewers: kubamracek, george.karpenkov, yln, samsonov, vitalybuka, krytarowski Subscribers: srhines, mgorny, fedor.sergeev, #sanitizers, llvm-commits Differential Revision: https://reviews.llvm.org/D55740 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@351398 91177308-0d34-0410-b5e6-96231b3b80d8

* [TSan] Report proper error on allocator failures instead of CHECK(0)-ingAlex Shlyapnikov2018-06-181-6/+22
| | | | | | | | | | | | | | | | | | | | | | Summary: Following up on and complementing D44404 and other sanitizer allocators. Currently many allocator specific errors (OOM, for example) are reported as a text message and CHECK(0) termination, no stack, no details, not too helpful nor informative. To improve the situation, detailed and structured common errors were defined and reported under the appropriate conditions. Common tests were generalized a bit to cover a slightly different TSan stack reporting format, extended to verify errno value and returned pointer value check is now explicit to facilitate debugging.
