2017-04-24[cfi] Disable ThinLTO + CFI tests on Windows.Evgeniy Stepanov
PR32770. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@301235 91177308-0d34-0410-b5e6-96231b3b80d8
2017-04-22[cfi] Disable thinlto tests on Darwin.Ahmed Bougacha
These were added in r301016, but they're failing, because -fsanitize=cfi seemingly causes -flto=thin to emit raw bitcode objects, rather than the mach-o-wrapped bitcode we emit with -flto=thin alone. That causes all tests to fail with ld64 errors. Filed PR32741. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@301065 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.

2016-01-08Fix CMake warning in CFI tests.Evgeniy Stepanov
CFI tests do not require the CFI runtime library on Windows. Do not add "cfi" as a dependency of "check-cfi" in that case. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@257202 91177308-0d34-0410-b5e6-96231b3b80d8
2015-12-15Cross-DSO control flow integrity (compiler-rt part).Evgeniy Stepanov
This is an initial version of the runtime cross-DSO CFI support library. It contains a number of FIXMEs, ex. it does not support the diagnostic mode nor dlopen/dlclose, but it works and can be tested. Diagnostic mode, in particular, would require some refactoring (we'd like to gather all CFI hooks in the UBSan library into one function so that we could easier pass the diagnostic information down to __cfi_check). It will be implemented later. Once the diagnostic mode is in, I plan to create a second test configuration to run all existing tests in both modes. For now, this patch includes only a few new cross-DSO tests. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@255695 91177308-0d34-0410-b5e6-96231b3b80d8

libraries." This reverts r255170. This change caused a bunch of bot failures and needs to be revised. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@255184 91177308-0d34-0410-b5e6-96231b3b80d8
2015-12-09[CMake] Provide options for toggling on and off various runtime libraries.Chris Bieneman
Summary: Rather than having to add new "experimental" options each time someone wants to work on bringing a sanitizer to a new platform, this patch makes options for all of them. The default values for the options are set by the platform checks that would have enabled them, but they can be overridden on or off.

2015-08-11[cmake] Hoist check for LLD sources up into root CMakeLists.txtReid Kleckner
We will use this for ASan on Windows soon. When the ELF port of LLD matures, we can add other sanitizer integration tests to make sure they work with LLD. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@244549 91177308-0d34-0410-b5e6-96231b3b80d8

2015-07-08CFI: Get check-cfi passing on Windows.Peter Collingbourne
Specifically: - Start using %expect_crash. - Provide an implementation of __ubsan::getDynamicTypeInfoFromVtable for the Microsoft C++ ABI. This is all that is needed for CFI diagnostics; UBSan's -fsanitize=vptr also requires an implementation of __ubsan::checkDynamicType. - Build the sanitizer runtimes against the release version of the C runtime, even in debug builds. - Accommodate demangling differences in tests.
