* [compiler-rt] Fix broken sanitizer bots (hopefully)Jonas Hahnfeld2019-02-171-1/+1
| | | | | | | | | | | | | | | | | | | According to the logs and local debugging there were two issues: 1) tsan tests listed libc++.a before the source file. That's usually ok for shared libraries, but the linker will not add symbols from a static library unless needed at that time. As a result the tests that rely upon symbols from the library (and not only include the headers) had undefined references. To solve this I'm adding a new substitution %link_libcxx_tsan which expands to libc++.a if available. 2) The target Fuzzer-x86_64-Test linked in SANITIZER_TEST_CXX_LIBRARIES which defaults to -lstdc++. This resulted in error messages like hidden symbol '_ZdlPv' is not defined locally hidden symbol '_Znwm' is not defined locally when using GNU gold (ld.bfd and lld are fine). Removing the linkage is fine because we build a custom libc++ for that purpose. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@354231 91177308-0d34-0410-b5e6-96231b3b80d8
* [compiler-rt] Get rid of "%T" expansionsFilipe Cabecinhas2018-07-101-4/+7
| | | | | | | | | | | | | | | | | | | Summary: Original patch by Kuba Mracek The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in compiler-rt.

* [compiler-rt] [tsan] Enable TSan for AArch64/42-bit VMAAdhemerval Zanella2015-08-281-1/+1
| | | | | | | | | | | | This patch adds support for tsan on aarch64-linux with 42-bit VMA (current default config for 64K pagesize kernels). The support is enabled by defining the SANITIZER_AARCH64_VMA to 42 at build time for both clang/llvm and compiler-rt. The default VMA is 39 bits. It also enabled tsan for previous supported VMA (39). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@246330 91177308-0d34-0410-b5e6-96231b3b80d8
* [tsan] Enable tsan for aarch64Adhemerval Zanella2015-08-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enabled TSAN for aarch64 with 39-bit VMA layout. As defined by tsan_platform.h the layout used is: 0000 4000 00 - 0200 0000 00: main binary 2000 0000 00 - 4000 0000 00: shadow memory 4000 0000 00 - 5000 0000 00: metainfo 5000 0000 00 - 6000 0000 00: - 6000 0000 00 - 6200 0000 00: traces 6200 0000 00 - 7d00 0000 00: - 7d00 0000 00 - 7e00 0000 00: heap 7e00 0000 00 - 7fff ffff ff: modules and main thread stack Which gives it about 8GB for main binary, 4GB for heap and 8GB for modules and main thread stack. Most of tests are passing, with the exception of: * ignore_lib0, ignore_lib1, ignore_lib3 due a kernel limitation for no support to make mmap page non-executable. * longjmp tests due missing specialized assembly routines. These tests are xfail for now. The only tsan issue still showing is: rtl/TsanRtlTest/Posix.ThreadLocalAccesses Which still required further investigation. The test is disable for aarch64 for now. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@244055 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix suppressions file usageFilipe Cabecinhas2014-12-181-1/+1
| | | | | | | | | | | | | | | | | | Summary: Always quote suppressions files given to *_OPTIONS. This will make it not break when given full Windows paths (otherwise, parsing would stop after the drive's letter + ':'). Also fix one or two cases where the suppression files' extensions were not *.supp. Reviewers: samsonov, kcc Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D6680 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@224529 91177308-0d34-0410-b5e6-96231b3b80d8
