libsanitizer/ 2015-10-20 Maxim Ostapenko <m.ostapenko@partner.samsung.com> * All source files: Merge from upstream r250806. * configure.ac (link_sanitizer_common): Add -lrt flag. * configure.tgt: Enable TSAN and LSAN for aarch64-linux targets. Set CXX_ABI_NEEDED=true for darwin. * asan/Makefile.am (asan_files): Add new files. (DEFS): Add DCAN_SANITIZE_UB=0 and remove unused and legacy DASAN_FLEXIBLE_MAPPING_AND_OFFSET=0. * asan/Makefile.in: Regenerate. * ubsan/Makefile.am (ubsan_files): Add new files. (DEFS): Add DCAN_SANITIZE_UB=1. (libubsan_la_LIBADD): Add -lc++abi if CXX_ABI_NEEDED is true. * ubsan/Makefile.in: Regenerate. * tsan/Makefile.am (tsan_files): Add new files. (DEFS): Add DCAN_SANITIZE_UB=0. * tsan/Makefile.in: Regenerate. * sanitizer_common/Makefile.am (sanitizer_common_files): Add new files. * sanitizer_common/Makefile.in: Regenerate. * asan/libtool-version: Bump the libasan SONAME.
