2017-11-13Allow compiler-rt test targets to work with multi-config CMake generatorsGreg Bedwell
Multi-config CMake generators need lit to be able to resolve paths of artifacts from previous build steps at lit time, rather than expect them to be fully resolved at CMake time as they may contain the build mode.

2017-10-02[cmake] Add a separate CMake var to control profile runtimeMichal Gorny
Make it possible to control building profile runtime separately from other options. Before r313549, the profile runtime building was controlled along with sanitizers. However, since that commit it is built unconditionally which results in multiple builds for people building different runtimes separately.

2017-09-18[cmake] Make it possible to build and test profile without sanitizersVedant Kumar
This should fix an issue which arises when running check-compiler-rt on the coverage bot: http://green.lab.llvm.org/green/job/clang-stage2-coverage-R_build/1590/ The bot doesn't build the sanitizers, but the check-compiler-rt target always expects the profile runtime to exist. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@313549 91177308-0d34-0410-b5e6-96231b3b80d8

This predicate compares the host's marketing OS version to one passed as argument. Currently, only darwin targets are supported. This is done by parsing the SystemVersion.plist file. Also added in this patch is some lit testing infrastructure for builtins, which previously had none. This part of the patch was written by Alex Lorenz (with some minor modifications).

2016-11-14[asan/win] Delay load dbghelp.dll to delay ucrtbase.dll initializationReid Kleckner
Summary: ASan needs to initialize before ucrtbase.dll so that it can intercept all of its heap allocations. New versions of dbghelp.dll depend on ucrtbase.dll, which means both of those DLLs will initialize before the dynamic ASan runtime. By lazily loading dbghelp.dll with LoadLibrary, we avoid the issue. Eventually, I would like to remove our dbghelp.dll dependency in favor of always using llvm-symbolizer.exe, but this seems like an acceptable interim solution.

Durning standalone builds (which includes runtimes builds) we want to create a target named check-compiler-rt. Additionally we also create check-all if it doesn't already exist as a convienence target that depends on check-compiler-rt. This allows us to generate a single check target that invokes lit for all test suites in the runtimes projects, while avoiding name collision of check-all and not breaking existing workflows. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@279334 91177308-0d34-0410-b5e6-96231b3b80d8

2016-06-07[sanitizer] Initial implementation of a Hardened AllocatorKostya Serebryany
Summary: This is an initial implementation of a Hardened Allocator based on Sanitizer Common's CombinedAllocator. It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast. The following were implemented: - additional consistency checks on the allocation function parameters and on the heap chunks; - use of checksum protected chunk header, to detect corruption; - randomness to the allocator base; - delayed freelist (quarantine), to mitigate use after free and overall determinism. Additional mitigations are in the works.

The common sanitizer flags are supported such as verbosity and log_path. + An initial simple test. Still TODO: common code for libc interceptors and shadow memory mapping, and tool-specific code for shadow state updating.

2014-02-19[CMake] Add the way to run tests in standalone build.Alexey Samsonov
1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to get necessary LLVM source/binary directories. 2) Add basic support for running lit tests (check-xsan commands). For now this "support" is far from what we want: * unit tests are not built currently. * lit tests use Clang/compiler-rt from LLVM build directory, not the host compiler or just-built compiler-rt libraries. We should make a choice on the way we intend ti run compiler-rt lit testsuite: a) use either Clang from LLVM build tree, or the host compiler. b) use either just-built runtimes, or the runtimes shipped with the host compiler. Using just-built runtimes is tricky - we have to know where to put them, so that Clang/GCC driver would pick them up (and not overwrite the existing runtimes). Using a host compiler instead of Clang from LLVM build tree will give us a chance to run lit tests under GCC (which already has support for several sanitizers). That is, I tend to make the following choice: if we're in a standalone compiler-rt build, use host compiler with its set of runtime libraries to run lit tests. This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in a standalone build - the latter wouldn't invoke the former. Note that if we decide to fix LLVM/Clang/compiler-rt build system so that it would configure/build compiler-rt with just-built Clang (as we do in Makefile-based build), this will not be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt before running compiler-rt tests. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@201656 91177308-0d34-0410-b5e6-96231b3b80d8
