2018-06-01Add weak definitions of trace-cmp hooks to dfsanKostya Serebryany
Summary: This allows to build and link the code with e.g. -fsanitize=dataflow -fsanitize-coverage=trace-pc-guard,pc-table,func,trace-cmp w/o providing (all) the definitions of trace-cmp hooks. This is similar to dummy hooks provided by asan/ubsan/msan for the same purpose, except that some of the hooks need to have the __dfsw_ prefix since we need dfsan to replace them.

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).

2016-08-12[mips] XFAIL the new mips64el compiler-rt tests that fail on clang-cmake-mipsel.Daniel Sanders
The mips64el compiler-rt build has recently been enabled. XFAIL the failing tests to make the buildbot green again. The two asan tests require the integrated assembler. This will be fixed soon for Debian mips64el but not for any other mips64el targets since doing so requires triple-related issues to be fixed.. The msan tests are largely failing because caused by a kernel update (a patch has already been posted for this). I'm not sure why the dfsan test fails yet. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@278504 91177308-0d34-0410-b5e6-96231b3b80d8
2016-07-11[compiler-rt] Fix VisualStudio virtual folders layoutEtienne Bergeron
Summary: This patch is a refactoring of the way cmake 'targets' are grouped. It won't affect non-UI cmake-generators. Clang/LLVM are using a structured way to group targets which ease navigation through Visual Studio UI. The Compiler-RT projects differ from the way Clang/LLVM are grouping targets. This patch doesn't contain behavior changes.

2016-02-09[dfsan] Run the tests for each supported arch and suffix each one to ↵Daniel Sanders
distinguish them. Summary: Previously, the tests only ran for the 64-bit equivalent of the default target (see -m64). Given the supported architecture list only contains 64-bit targets, this happens to work out the same as the supported targets in most cases but may matter for X86_64/X86_64h on Darwin. For other targets, the practical effect is that the test names contain the architecture. This resolves some confusion when msan tests fail since their name no longer implies that they are trying to test the default target.
