This patch imports the runtime library in the GCC tree, ensures that -lasan is passed to the linker when -faddress-sanitizer is used and sets up the build system accordingly. ChangeLog: * configure.ac: Add libsanitizer to target_libraries. * Makefile.def: Ditto. * configure: Regenerate. * Makefile.in: Regenerate. * libsanitizer: New directory for asan runtime. Contains an empty tsan directory. gcc/ChangeLog: * gcc.c (LINK_COMMAND_SPEC): Add -laddress-sanitizer to link command if -faddress-sanitizer is on. libsanitizer: Initial checkin: migrate asan runtime from llvm.
