2017-11-16[asan] Properly mark or disable tests that only work with shadow scale of 3Walter Lee
Differential Revision: https://reviews.llvm.org/D39774 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@318471 91177308-0d34-0410-b5e6-96231b3b80d8
2017-11-13[asan] Add CMake hook to override shadow scale in compiler_rtWalter Lee
Allow user to override shadow scale in compiler_rt by passing -DCOMPILER_RT_ASAN_SHADOW_SCALE=n to CMake. Propagate the override shadow scale value via a compiler define to compiler-rt and asan tests. Tests will use the define to partially disable unsupported tests. Set "-mllvm -asan-mapping-scale=<n>" for compiler_rt tests.

2017-10-12[cmake] [asan] Remove unnecessary gtest dep from dynamic testsMichal Gorny
Remove the redundant dependency on 'gtest' target from the dynamic tests in non-MSVC environment. The tests reuse compiled objects from ASAN_INST_TEST_OBJECTS, and therefore they have been built against gtest already. This both fixes the spurious dependency on 'gtest' target that breaks stand-alone builds, and brings the dynamic tests more in line with regular tests which do not pass this dependency to add_compiler_rt_test() through generate_compiler_rt_tests().

2017-08-29Shorten filenames of tests (-with-calls to -calls)Kamil Rytarowski
Summary: The NetBSD's 8(beta) versions of kernel functions to retrieve program name (vnode to path translator) and process memory map have internal limit of processing filenames with maximum of 31 characters. Filenames like Asan-x86_64-with-calls-Noinst-Test break this limit and affect tests. Rename "-with-calls" to "-calls". This changes fixes all issues for the Address Sanitizer test target (check-asan) on the current NetBSD support caused by long filenames.

2017-08-28[asan] Move __asan_handle_no_return to public headerPetr Hosek
Heretofore asan_handle_no_return was used only by interceptors, i.e. code private to the ASan runtime. However, on systems without interceptors, code like libc++abi is built with -fsanitize=address itself and should call asan_handle_no_return directly from __cxa_throw so that no interceptor is required.

2017-08-15[sanitizers CMake] NFC Refactor the logic for compiling and generating testsGeorge Karpenkov
into a function. Most CMake configuration under compiler-rt/lib/*/tests have almost-the-same-but-not-quite functions of the form add_X_[unit]tests for compiling and running the tests. Much of the logic is duplicated with minor variations across different sub-folders. This can harm productivity for multiple reasons: For newcomers, resulting CMake files are very large, hard to understand, and hide the intention of the code. Changes for enabling certain architectures end up being unnecessarily large, as they get duplicated across multiple folders. Adding new sub-projects requires more effort than it should, as a developer has to again copy-n-paste the configuration, and it's not even clear from which sub-project it should be copy-n-pasted. With this change the logic of compile-and-generate-a-set-of-tests is extracted into a function, which hopefully makes writing and reading CMake much easier.

2017-07-28[sanitizers] Sanitizer tests CMake clean up: try #2George Karpenkov
This patch addresses two issues: Most of the time, hacks with `if/else` in order to get support for multi-configuration builds are superfluous. The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it expands to `.` on all single-configuration builds, and to a configuration name otherwise. The `if/else` hacks for the library name generation should also not be done, as CMake has `TARGET_FILE` generator expression precisely for this purpose, as it expands to the exact filename of the resulting target.

2016-12-26[inline-asm]No error for conflict between inputs\outputs and clobber listMarina Yatsina
Updated test according to commit 290539: According to extended asm syntax, a case where the clobber list includes a variable from the inputs or outputs should be an error - conflict. for example: const long double a = 0.0; int main() { char b; double t1 = a; __asm__ ("fucompp": "=a" (b) : "u" (t1), "t" (t1) : "cc", "st", "st(1)"); return 0; } This should conflict with the output - t1 which is st, and st which is st aswell. The patch fixes it. Commit on behald of Ziv Izhar.
