[asan] attempting to fix the debian bot (on ubuntu the test builds; on debian it complains that _SC_PAGESIZE is unknown)

llvm-svn: 182462

[asan] fix dlclose-test to work with non-4K pages. Properly disable interface_symbols_linux on non-x86

llvm-svn: 182461

[asan] workaround for asan bug 189 (swapcontext followed by throw gets OOM kill). Also, disable swapcontext_test on non-x86. Fix lint

llvm-svn: 182456

Keeps it consistent between ASan and LSan.

Also, define CAN_SANITIZE_LEAKS.

[ASan] Don't run fast unwinder tests on 32-bit Linux as fast unwinder may be unexpectedly smart on some hosts

See https://code.google.com/p/address-sanitizer/issues/detail?id=187 for the details

We need this to avoid races when ASan and LSan are used together.

llvm-svn: 182252

Also fix wrong alignment maths and an outdated comment

[sanitizer] factor out ByteMap from SizeClassAllocator32 so that it can be later replaced with a more memory-efficient implementation on 64-bit.

Before, we had an unused internal_getpid function for Linux, and a
platform-independent GetPid function.  To make the naming conventions
consistent for syscall-like functions, the GetPid syscall wrapper
in sanitizer_posix.cc is moved to sanitizer_mac.cc, and GetPid is
renamed to internal_getpid, bringing the Linux variant into use.

Introduce a new object library, RTSanitizerCommonLibc, which will contain
the subset of sanitizer_common with libc dependencies. RTSanitizerCommon
contains the remainder of sanitizer_common, and is intended to have no
libc dependencies. Begin moving code to RTSanitizerCommonLibc, starting
with sanitizer_common.cc, whose libc-dependent portion is moved to
sanitizer_common_libcdep.cc, the first member of the new library.

This split affects the CMake build only.  The makefile build continues
to produce the full sanitizer_common library.

[ASan] Make the regression test for time(NULL) Linux-specific, as it crashes on Darwin (and the problem used to occur on Linux).
Do not use zero-based shadow for the time() test.

llvm-svn: 182107

[ASan] Fix allow_user_segv.cc on Darwin (32-bit build required a SIGBUS handler instead of the SIGSEGV one)

[asan] symbolize when possible, even if ASAN_SYMBOLIZER_PATH is not provided. On Linux this will use dl_iterate_phdr instead of /proc/self/maps, even if the symbolizer is not installed

Some flags that are common to ASan/MSan/TSan/LSan have been moved to
sanitizer_common.
