2015-06-26[ASan] Clean up obsolete stats.Alexey Samsonov
Remove stats that we no longer collect after the allocator change. Use proper constant SizeClassMap::kNumClasses to fix potential buffer overflow (https://code.google.com/p/address-sanitizer/issues/detail?id=397). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@240816 91177308-0d34-0410-b5e6-96231b3b80d8
2014-08-12[Sanitizer] Kill deprecated allocator interfaces in ASan, MSan and TSan in ↵Alexey Samsonov
favor of a unified interface in <sanitizer/allocator_interface.h>. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@215469 91177308-0d34-0410-b5e6-96231b3b80d8
2014-07-07Generalize sanitizer allocator public interface.Alexey Samsonov
Introduce new public header <sanitizer/allocator_interface.h> and a set of functions __sanitizer_get_ownership(), __sanitizer_malloc_hook() etc. that will eventually replace their tool-specific equivalents (__asan_get_ownership(), __msan_get_ownership() etc.). Tool-specific functions are now deprecated and implemented as stubs redirecting to __sanitizer_ versions (which are implemented differently in each tool). Replace all uses of __xsan_ versions with __sanitizer_ versions in unit and lit tests. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@212469 91177308-0d34-0410-b5e6-96231b3b80d8
2014-05-21[msan] Chained origins re-design.Evgeniy Stepanov
Generalize StackDepot and create a new specialized instance of it to efficiently (i.e. without duplicating stack trace data) store the origin history tree. This reduces memory usage for chained origins roughly by an order of magnitude. Most importantly, this new design allows us to put two limits on stored history data (exposed in MSAN_OPTIONS) that help avoid exponential growth in used memory on certain workloads. See comments in lib/msan/msan_origin.h for more details. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@209284 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-29Relocate the external headers provided by ASan and the common sanitizerChandler Carruth
library. These headers are intended to be available to user code when built with AddressSanitizer (or one of the other sanitizer's in the future) to interface with the runtime library. As such, they form stable external C interfaces, and the headers shouldn't be located within the implementation. I've pulled them out into what seem like fairly obvious locations and names, but I'm wide open to further bikeshedding of these names and locations. I've updated the code and the build system to cope with the new locations, both CMake and Makefile. Please let me know if this breaks anyone's build. The eventual goal is to install these headers along side the Clang builtin headers when we build the ASan runtime and install it. My current thinking is to locate them at: <prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h <prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h <prefix>/lib/clang/X.Y/include/sanitizer/... But maybe others have different suggestions? Fixing the style of the #include between these headers at least unblocks experimentation with installing them as they now should work when installed in these locations. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@162822 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21[asan] Support for %z to Printf()Evgeniy Stepanov
At the moment, asan internal Printf() uses %l modifier for printing values of size_t and related types. This works, because we control both the implementation of Printf and all its uses, but can be a little misleading. This change adds support for %z to Printf(). All callers that print sizes and pointers as integers are switched to %zu / %zx. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@153177 91177308-0d34-0410-b5e6-96231b3b80d8
