2018-07-10[CMake] Add compiler-rt header files to the list of sources for targetsDan Liew
when building with an IDE so that header files show up in the UI. This massively improves the development workflow in IDEs. To implement this a new function `compiler_rt_process_sources(...)` has been added that adds header files to the list of sources when the generator is an IDE. For non-IDE generators (e.g. Ninja/Makefile) no changes are made to the list of source files. The function can be passed a list of headers via the `ADDITIONAL_HEADERS` argument. For each runtime library a list of explicit header files has been added and passed via `ADDITIONAL_HEADERS`. For `tsan` and `sanitizer_common` a list of headers was already present but it was stale and has been updated to reflect the current state of the source tree. The original version of this patch used file globbing (`*.{h,inc,def}`) to find the headers but the approach was changed due to this being a CMake anti-pattern (if the list of headers changes CMake won't automatically re-generate if globbing is used). The LLVM repo contains a similar function named `llvm_process_sources()` but we don't use it here for several reasons: * It depends on the `LLVM_ENABLE_OPTION` cache variable which is not set in standalone compiler-rt builds. * We would have to `include(LLVMProcessSources)` which I'd like to avoid because it would include a bunch of stuff we don't need.

2018-04-16[sanitizer] Split Symbolizer/StackTraces from core RTSanitizerCommonKostya Kortchinsky
Summary: Host symbolizer & stacktraces related code in their own RT: `RTSanitizerCommonSymbolizer`, which is "libcdep" by nature. Symbolizer & stacktraces specific code that used to live in common files is moved to a new file `sanitizer_symbolizer_report.cc` as is. The purpose of this is the enforce a separation between code that relies on symbolization and code that doesn't. This saves the inclusion of spurious code due to the interface functions with default visibility, and the extra data associated. The following sanitizers makefiles were modified & tested locally: - dfsan: doesn't require the new symbolizer RT - esan: requires it - hwasan: requires it - lsan: requires it - msan: requires it - safestack: doesn't require it - xray: doesn't require it - tsan: requires it - ubsan: requires it - ubsan_minimal: doesn't require it - scudo: requires it (but not for Fuchsia that has a minimal runtime) This was tested locally on Linux, Android, Fuchsia.

2018-03-22[sanitizer] Split coverage into separate RT in sanitizer_commonKostya Kortchinsky
Summary: `sanitizer_common`'s coverage support is fairly well separated, and libcdep by default. Several sanitizers don't make use of coverage, and as far as I can tell do no benefit from the extra dependencies pulled in by the coverage public interface functions. The following sanitizers call `InitializeCoverage` explicitely: MSan, ASan, LSan, HWAsan, UBSan. On top of this, any sanitizer bundling RTUBSan should add the coverage RT as well: ASan, Scudo, UBSan, CFI (diag), TSan, MSan, HWAsan. So in the end the following have no need: DFSan, ESan, CFI, SafeStack (nolibc anyway), XRay, and the upcoming Scudo minimal runtime. I tested this with all the sanitizers check-* with gcc & clang, and in standalone on Linux & Android, and there was no issue. I couldn't test this on Mac, Fuchsia, BSDs, & Windows for lack of an environment, so adding a bunch of people for additional scrunity. I couldn't test HWAsan either.

2018-01-17[Sanitizers] Make common allocator agnostic to failure handling modes.Alex Shlyapnikov
Summary: Make common allocator agnostic to failure handling modes and move the decision up to the particular sanitizer's allocator, where the context is available (call stack, parameters, return nullptr/crash mode etc.) It simplifies the common allocator and allows the particular sanitizer's allocator to generate more specific and detailed error reports (which will be implemented later). The behavior is largely the same, except one case, the violation of the common allocator's check for "size + alignment" overflow is now reportied as OOM instead of "bad request". It feels like a worthy tradeoff and "size + alignment" is huge in this case anyway (thus, can be interpreted as not enough memory to satisfy the request). There's also a Report() statement added there.

2018-01-13[Sanitizers, LSan, Darwin] Allow for lack of VM_MEMORY_OS_ALLOC_ONCEFrancis Ricci
Summary: Some time ago, the sanitizers as of r315899 were imported into gcc mainline. This broke bootstrap on Darwin 10 and 11, as reported in GCC PR sanitizer/82824 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82824) due to the unconditional use of VM_MEMORY_OS_ALLOC_ONCE. This was only introduced in Darwin 13/Mac OS X 10.9. The use of the macro was introduced in r300450. I couldn't find any statement which Darwin versions are supposed to be supported by LLVM, but the trivial patch to use the macro only if present allowed the gcc bootstrap to finish. So far, I haven't tried building llvm/compiler-rt on Darwin 11. Maybe the patch is simple enough to go in nonetheless. Committing on behalf of ro.

Summary: Stop using the Linux solution with pthread_key_create(3). This approach does not work on NetBSD, because calling the thread destructor is not the latest operation on a POSIX thread entity. Detect _lwp_exit(2) call as it is really the latest operation called from a detaching POSIX thread. The pthread_key_create(3) solution also cannot be used in early libc/libpthread initialization on NetBSD as the system libraries are not bootstrapped enough.

2017-07-25Only scan global sections containing data in LSan on darwinFrancis Ricci
Summary: __DATA segments on Darwin contain a large number of separate sections, many of which cannot actually contain pointers, and contain const values or objc metadata. Not scanning sections which cannot contain pointers significantly improves performance. On a medium-sized (~4000 files) internal project, I saw a speedup of about 30% in standalone LSan's execution time (30% improvement in the time spent running LSan, not the total program time).

2017-07-18Don't call exit() from atexit handlers on DarwinFrancis Ricci
Summary: Calling exit() from an atexit handler is undefined behavior. On Linux, it's unavoidable, since we cannot intercept exit (_exit isn't called if a user program uses return instead of exit()), and I haven't seen it cause issues regardless. However, on Darwin, I have a fairly complex internal test that hangs roughly once in every 300 runs after leak reporting finishes, which is resolved with this patch, and is presumably due to the undefined behavior (since the Die() is the only thing that happens after the end of leak reporting). In addition, this is the way TSan works as well, where an atexit handler+Die() is used on Linux, and an _exit() interceptor is used on Darwin. I'm not sure if it's intentionally structured that way in TSan, since TSan sets up the atexit handler and the _exit() interceptor on both platforms, but I have observed that on Darwin, only the _exit() interceptor is used, and on Linux the atexit handler is used.

2017-07-17Only scan global sections containing data in LSan on darwinFrancis Ricci
Summary: __DATA segments on Darwin contain a large number of separate sections, most of which cannot actually contain pointers, and contain const values or objc metadata. Only scanning sections which can contain pointers greatly improves performance. On a medium-sized (~4000 files) internal project, I saw a speedup of about 50% in standalone LSan's execution time (50% improvement in the time spent running LSan, not the total program time).

parameters. NFC. Summary: This is the first in a series of patches to refactor sanitizer_procmaps to allow MachO section information to be exposed on darwin. In addition, grouping all segment information in a single struct is cleaner than passing it through a large set of output parameters, and avoids the need for annotations of NULL parameters for unneeded information. The filename string is optional and must be managed and supplied by the calling function. This is to allow the MemoryMappedSegment struct to be stored on the stack without causing overly large stack sizes.
