Kuba Brecka dfaac293dc [asan] Intercept and wrap XPC callback blocks
On recent OS X systems, blocks used as callbacks for XPC events (set up e.g. via xpc_connection_set_event_handler) are not later executed via the public libdispatch API (dispatch_async, etc). Because we don't intercept the path where the block is executed, we can fail to register the newly created dispatch thread. To fix that, let's intercept libxpc's APIs that take a block as a callback handler, and let's wrap these blocks in the same way as we do for libdispatch API.

* Unit tests should be passed ${DARWIN_osx_CFLAGS} because they're being built for OS X
* Test architectures should be filtered based on base system capabilities (i.e. don't try running x86_64h tests on pre-haswell hardware).

Reid Kleckner 89d994367a [windows] Fix or XFAIL remaining portable test failures and enable them
Summary:
This involved various fixes:

- Move a test that uses ulimit to Posix.

- Add a few "REQUIRES: shell" lines to tests using backtick subshell
  evaluation.

- The MSVC CRT buffers stdio if the output is a pipe by default. Some
  tests need that disabled to avoid interleaving test stdio with asan
  output.

- MSVC headers provide _alloca instead of alloca (go figure), so add a
  portability macro to the two alloca tests.

- XFAIL tests that rely on accurate symbols, we need to pass more flags
  to make that work.

- MSVC's printf implementation of %p uses upper case letters and doesn't
  add 0x, so do that manually.

- Accept "SEGV" or "access-violation" reports in crash tests.

Reid Kleckner 85220d0218 Use %env_asan_opts= substitution instead of 'env ASAN_OPTIONS=$ASAN_OPTIONS'
Summary:
The lit internal shell is used by default on Windows, and it does not
support bash variable expansion. Because bash variable expansion
interacts with tokenization, it is prohibitively difficult to make the
existing lit shell do general shell variable expansion.

The most common use of shell variables in the asan tests is to add
options to the default set of options set by lit.cfg. We can avoid the
need for variable expansion with a substitution that expands to 'env
ASAN_OPTIONS=<defaults:>'.

This has the side benefit of shortening the RUN lines, so it seemed
better than implementing limited variable expansion in lit.

Reid Kleckner 3f3af2cf74 [windows] Always use the lit shell on Windows, even if bash is present
Summary:
This is consistent with LLVM and Clang. The lit shell isn't a complete
bash implementation, but its behavior is more easily reproducible.  This
fixes some ubsan test failures.

One ubsan test requires a shell currently, so I added "REQUIRES: shell",
and the other doesn't work on Windows because it prints a stack trace
and uses a linker that doesn't support DWARF. We can fix it eventually
through other means.

Reid Kleckner 7d9e1e1259 [Windows] Use llvm-symbolizer before using dbghelp
Summary:
llvm-symbolizer understands both PDBs and DWARF, so it's a better bet if
it's available. It prints out the function parameter types and column
numbers, so I needed to churn the expected test output a bit.

This makes most of the llvm-symbolizer subprocessing code
target-independent. Pipes on all platforms use fd_t, and we can use the
portable ReadFromFile / WriteToFile wrappers in symbolizer_sanitizer.cc.
Only the pipe creation and process spawning is Windows-specific.

Please check that the libcdep layering is still correct. I don't know
how to reproduce the build configuration that relies on that.

Adhemerval Zanella 975998bf6a [asan] Enable asan for aarch64
This patch enables asan for aarch64/linux.  It marks it as 'unstable-release',
since some tests are failing due either kernel missing support of non-executable
pages in mmap or environment instability (infinite loop in juno reference
boards).

It sets decorate_proc_maps test to require stable-release, since the test expects
the shadow memory to not be executable and the support for aarch64 is only
added recently by Linux (da141706aea52c1a9 - 4.0).

Reid Kleckner 646386e779 [asan] Print VAs instead of RVAs for module offsets on Windows
Summary:
This is consistent with binutils and ASan behavior on other platforms,
and makes it easier to use llvm-symbolizer with WinASan. The
--relative-address flag to llvm-symbolizer is also no longer needed.

An RVA is a "relative virtual address", meaning it is the address of
something inside the image minus the base of the mapping at runtime.

A VA in this context is an RVA plus the "preferred base" of the module,
and not a real runtime address. The real runtime address of a symbol
will equal the VA iff the module is loaded at its preferred base at
runtime.

On Windows, the preferred base is stored in the ImageBase field of one
of the PE file header, and this change adds the necessary code to
extract it. On Linux, this offset is typically included in program and
section headers of executables.

ELF shared objects typically use a preferred base of zero, meaning the
smallest p_vaddr field in the program headers is zero. This makes it so
that PIC and PIE module offsets come out looking like RVAs, but they're
actually VAs. The difference between them simply happens to be zero.

Kuba Brecka a11cfb990a [asan] Rename the ABI versioning symbol to '__asan_version_mismatch_check' instead of abusing '__asan_init'
We currently version `__asan_init` and when the ABI version doesn't match, the linker gives a `undefined reference to '__asan_init_v5'` message. From this, it might not be obvious that it's actually a version mismatch error. This patch makes the error message much clearer by changing the name of the undefined symbol to be `__asan_version_mismatch_check_xxx` (followed by the version string). We obviously don't want the initializer to be named like that, so it's a separate symbol that is used only for the purpose of version checking.

Filipe Cabecinhas 91244924cb [ASan] Test churn for setting ASAN_OPTIONS=symbolize_vs_style=false
Summary:
This commit adds symbolize_vs_style=false to every instance of
ASAN_OPTIONS in the asan tests and sets
ASAN_OPTIONS=symbolize_vs_style=false in lit, for tests which don't set
it.

This way we don't need to make the tests be able to deal with both
symbolize styles.

This is the first patch in the series. I will eventually submit for the
other sanitizers too.

We need this change (or another way to deal with the different outputs) in
order to be able to default to symbolize_vs_style=true on some platforms.

Adding to this change, I'm also adding "env " before any command line
which sets environment variables. That way the test works on other host
shells, like we have if the host is running Windows.

Daniel Sanders 0568283e69 [asan] Print SHADOW_SCALE and SHADOW_GRANULARITY as decimal values.
Summary:
During the review of http://reviews.llvm.org/D9199 where I had originally
changed the debug_mapping.cc test to accept hexadecimal values, we realized
that SHADOW_SCALE and SHADOW_GRANULARITY ought to be printed as decimal values.
This patch makes that change.

This patch also adds a '0x' prefix to the SHADOW_OFFSET to make it clear that
it is hexadecimal while the other two are decimal.

Daniel Sanders 9316d89d55 [asan] debug_mapping.cc should also pass when the leading digit of SHADOW_SCALE is hexadecimal.
Summary:
Previously the CHECK directive for SHADOW_SCALE only matched decimal digits
causing it to match '7' on x86_64 instead of the whole value.

This fixes a failure on mips-linux-gnu targets where the leading digit is 'a'.
