2013-11-15Reapply asan coverage changes 194702-194704.Bob Wilson
I still don't know what is causing our bootstrapped LTO buildbots to fail, but llvm r194701 seems to be OK and I can't imagine that these changes could cause the problem. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194790 91177308-0d34-0410-b5e6-96231b3b80d8
2013-11-15Speculatively revert asan coverage changes 194702-194704.Bob Wilson
Apple's bootstrapped LTO builds have been failing, and these changes (along with llvm 194701) are the only things on the blamelist. I will either reapply these changes or help debug the problem, depending on whether this fixes the buildbots. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194779 91177308-0d34-0410-b5e6-96231b3b80d8

2013-10-15tsan: remove __sanitizer_set_report_fd function from public interfaceDmitry Vyukov

2013-02-15[asan] make asan work with 7fff8000 offset and prelinkKostya Serebryany
When prelink is installed in the system, prelink-ed libraries map between 0x003000000000 and 0x004000000000 thus occupying the shadow Gap, so we need so split the address space even further, like this: || [0x10007fff8000, 0x7fffffffffff] || HighMem || || [0x02008fff7000, 0x10007fff7fff] || HighShadow || || [0x004000000000, 0x02008fff6fff] || ShadowGap3 || || [0x003000000000, 0x003fffffffff] || MidMem || || [0x00087fff8000, 0x002fffffffff] || ShadowGap2 || || [0x00067fff8000, 0x00087fff7fff] || MidShadow || || [0x00008fff7000, 0x00067fff7fff] || ShadowGap || || [0x00007fff8000, 0x00008fff6fff] || LowShadow || || [0x000000000000, 0x00007fff7fff] || LowMem || Do it only if necessary. Also added a bit of profiling code to make sure that the mapping code is efficient. Added a lit test to simulate prelink-ed libraries. Unfortunately, this test does not work with binutils-gold linker. If gold is the default linker the test silently passes. Also replaced __has_feature(address_sanitizer) with __has_feature(address_sanitizer) || defined(__SANITIZE_ADDRESS__) in two places.

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
