* [asan] instrument memory accesses with unusual sizesKostya Serebryany2013-02-196-4/+41
| | | | | | | | | | | | | | | | This patch makes asan instrument memory accesses with unusual sizes (e.g. 5 bytes or 10 bytes), e.g. long double or packed structures. Instrumentation is done with two 1-byte checks (first and last bytes) and if the error is found __asan_report_load_n(addr, real_size) or __asan_report_store_n(addr, real_size) is called. asan-rt part Also fix lint. llvm-svn: 175508

| | | | | | | | | | | | | | | | | MaybeReexec() does now a tricky job to manage DYLD_INSERT_LIBRARIES in a safe way. Because we're using library interposition, it's critical for an instrumented app to be executed with the runtime library present in DYLD_INSERT_LIBRARIES list. Therefore if it's initially missing in that list, we append the runtime library name to the value of DYLD_INSERT_LIBRARIES and then exec() ourselves. On the other hand, some of the apps exec()ed by our program may not want to have ASan runtime library preloaded, so we remove the runtime library from the DYLD_INSERT_LIBRARIES if it's already there. Users may want to preload other libraries using DYLD_INSERT_LIBRARIES, so we preserve those. llvm-svn: 175276
* [asan] make asan work with 7fff8000 offset and prelinkKostya Serebryany2013-02-157-47/+237
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Patch partially by Jakub Jelinek. llvm-svn: 175263
