Nico Weber 6a4e0dd1a6 When building without DIA SDK, don't set suppressions.cpp fail
This test requires llvm-symbolizer to be able to convert a stack
address into a function name.  It is only able to do this if the
DIA SDK was found at cmake time.  Add a lit feature for this,
and let the test depend on it.

Evgeniy Stepanov da1cf9287c Cross-DSO control flow integrity (compiler-rt part).
This is an initial version of the runtime cross-DSO CFI support
library.

It contains a number of FIXMEs, ex. it does not support the
diagnostic mode nor dlopen/dlclose, but it works and can be tested.
Diagnostic mode, in particular, would require some refactoring (we'd
like to gather all CFI hooks in the UBSan library into one function
so that we could easier pass the diagnostic information down to
__cfi_check). It will be implemented later.

Once the diagnostic mode is in, I plan to create a second test
configuration to run all existing tests in both modes. For now, this
patch includes only a few new cross-DSO tests.

This patch enables the safestack for aarch64. The frontend already have
it enabled on all supported architectures and no adjustment is required
in llvm.

The compiler-rt adjustments are basically add on the cmake configuration

kernel configuration).

Summary:
Rather than having to add new "experimental" options each time someone wants to work on bringing a sanitizer to a new platform, this patch makes options for all of them.

The default values for the options are set by the platform checks that would have enabled them, but they can be overridden on or off.

Sumanth Gundapaneni dbb8a1d8e7 Fix the target specific "-msse3" flag check in CMake. NFC
msse3 is a target dependent flag and must be guarded as check_cxx_compiler_flag()
checks only for compiler error messages and ignores warnings. Earlier COMPILER_RT_HAS_MSSE3_FLAG
is set to "TRUE" for all targets as clang emits warnings and the compilation spits unnecessary 
warnings for non-X86 targets. This issue is fixed by coupling the flag with "-Werror"

Bill Schmidt 2979162732 [PPC64, TSAN] LLVM basic enablement of thread sanitizer for PPC64 (BE and LE)
This patch is by Simone Atzeni with portions by Adhemerval Zanella.

This contains the LLVM patches to enable the thread sanitizer for
PPC64, both big- and little-endian.  Two different virtual memory
sizes are supported:  Old kernels use a 44-bit address space, while
newer kernels require a 46-bit address space.

There are two companion patches that will be added shortly.  There is
a Clang patch to actually turn on the use of the thread sanitizer for
PPC64.  There is also a patch that I wrote to provide interceptor
support for setjmp/longjmp on PPC64.

This adds a new name for ARM32 (armhf).  We now force that the default build for

for these names based on the floating point ABI.  The functions are built
identically (the functions are marked as AAPCS, so the calling convention does
not change, as per the RTABI specification), however, the object file contains
attributes indicating the build configuration which the linker will ensure are
not mix and matched.  We now built the appropriate named archive so that we can
link properly.

Adhemerval Zanella 19074450ee [MSan] Enable MSAN for aarch64
This patch enabled msan for aarch64 with 39-bit VMA and 42-bit VMA.
As defined by lib/msan/msan.h the memory layout used is for 39-bit is:

   00 0000 0000 - 40 0000 0000:  invalid
   40 0000 0000 - 43 0000 0000:  shadow
   43 0000 0000 - 46 0000 0000:  origin
   46 0000 0000 - 55 0000 0000:  invalid
   55 0000 0000 - 56 0000 0000:  app (low)
   56 0000 0000 - 70 0000 0000:  invalid
   70 0000 0000 - 80 0000 0000:  app (high)

And for 42-bit VMA:

   000 0000 0000 - 100 0000 0000:  invalid
   100 0000 0000 - 11b 0000 0000:  shadow
   11b 0000 0000 - 120 0000 0000:  invalid
   120 0000 0000 - 13b 0000 0000:  origin
   13b 0000 0000 - 2aa 0000 0000:  invalid
   2aa 0000 0000 - 2ab 0000 0000:  app (low)
   2ab 0000 0000 - 3f0 0000 0000:  invalid
   3f0 0000 0000 - 400 0000 0000:  app (high)

Most of tests are passing with exception of:

   * Linux/mallinfo.cc
   * chained_origin_limits.cc
   * dlerror.cc
   * param_tls_limit.cc
   * signal_stress_test.cc
   * nonnull-arg.cpp

The 'Linux/mallinfo.cc' is due the fact AArch64 returns the sret in 'x8'
instead of default first argument 'x1'.  So a function prototype that
aims  to mimic (by using first argument as the return of function) won't
work. For GCC one can make a register alias (register var asm ("r8")), but
for clang it detects is an unused variable and generate wrong code.

The 'chained_origin_limits' is probably due a wrong code generation,
since it fails only when origin memory is used
(-fsanitize-memory-track-origins=2) and only in the returned code
(return buf[50]).

The 'signal_streess_test' and 'nonnull-arg' are due currently missing variadic
argument handling in memory sanitizer code instrumentation on LLVM side.

Both 'dlerror' and 'param_tls_test' are unknown failures that require
further investigation.

All the failures are XFAIL for aarch64 for now.

Instead, assume we're going to target triple specified by
COMPILER_RT_DEFAULT_TARGET_TRIPLE and build runtimes for this triple
(and hope that the host compiler can target them).

This will help users that use cross-compiler on their host to build
Clang that would work on a different architecture. This will also come in
handy if one would want to configure several compiler-rt build trees on
the same host, using just-built Clang that can target many
architectures.

The old code could not be made to work on Darwin as a result of the refactoring of add_compiler_rt_runtime, so I had to rework the way they are built for Darwin. This solution is not ideal and will be fixed in subsequent commits. I just want to get this in so everything is working again.

Which gives it about 8GB for main binary, 4GB for heap and 8GB for
modules and main thread stack.

Most of tests are passing, with the exception of:

 * ignore_lib0, ignore_lib1, ignore_lib3 due a kernel limitation for

 * longjmp tests due missing specialized assembly routines.

These tests are xfail for now.

Hans Wennborg 78bea23be0 [CMake] Pass -march=i686 when targeting i686 (PR24222)
Clang will not define __i686__, even when the target triple is i686,
without -march=i686.

With this patch, the compiler-rt build will successfully detect that
Clang can target i686.

The open_memstream.cc test is a little funny. Before my patch, it
was invoked with "-m32 -m64". To make it work after my -march
change, I had to add '-march=x86-64'.

Summary:
Although we assume that we can always target host triple, relax
this check to avoid failing at configure-time for cases when we are
not able to correctly infer/verify host triple for some reasons.

Evgeniy Stepanov 8e9c70be7f Add descriptive names to sanitizer entries in /proc/self/maps. Helps debugging.
This is done by creating a named shared memory region, unlinking it
and setting up a private (i.e. copy-on-write) mapping of that instead
of a regular anonymous mapping. I've experimented with regular
(sparse) files, but they can not be scaled to the size of MSan shadow
mapping, at least on Linux/X86_64 and ext3 fs.

Controlled by a common flag, decorate_proc_maps, disabled by default.

This patch has a few shortcomings:
* not all mappings are annotated, especially in TSan.
* our handling of memset() of shadow via mmap() puts small anonymous
  mappings inside larger named mappings, which looks ugly and can, in
  theory, hit the mapping number limit.

Summary:
This will allow us to enable it on the buildbot (and then enable a

The problem is that gcc for Mips does not accept -m32/-m64 like clang does.
We therefore need to use the nearest equivalent -mips32r2/-mips64r2. We must
also specify -mabi=64 in the -mips64r2 case since gcc's default ABI has
traditionally been N32 whereas clang's is N64.

Alexey Samsonov 09dce3b7e5 [UBSan] Embed UBSan into ASan runtime (compiler-rt part).
Summary:
Change the way we use ASan and UBSan together. Instead of keeping two
separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan
into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on
a platform, all UBSan sources are just compiled into dummy empty object
files. UBSan initialization code (e.g. flag parsing) is directly called
from ASan initialization, so we are able to enforce correct
initialization order.

This mirrors the approach we already use for ASan+LSan. This change
doesn't modify the way we use standalone UBSan.

This commit changes the strategy for building shared ASan runtime

  - COMPILER_RT_BUILD_SHARED_ASAN CMake option is removed. We now
    always build shared ASan runtime (it is the default on Android,
    Windows and Mac, and not the default on Linux and FreeBSD).
  - Platforms, which use static runtime by default now have
    "check-asan-dynamic" testsuite. This testsuite contains instrumented
    unit tests, and ASan lit tests, and runs them with shared ASan
    runtime. This testsuite is *not* a part of "check-asan" and
    *not* a part of "check-all", as adding 1000 more test cases, which
    duplicate existing ones is costly. However, you're welcome to
    add this command to your buildbot.

This means for example that clang_rt.asan_dynamic-i386.dll will get built

instead of being built in the bin/ directory and not installed at all.

Summary:
I don't know anything about profiling but it seems to work out of the

A few tests needed tweaking because PowerPC64 IR declares main with
"define signext i32 @main" instead of just "define i32 @main".

This also fixes the asan asan_and_llvm_coverage_test test, which
compiles with -coverage so requires that a profiling version of
libclang_rt has been built.

Renato Golin 34cb659103 Separating ARM/AArch64 Compiler-RT tests
Makes sure ARM bots don't run AArch64 and vice-versa, since not all
AArch64 systems can run AArch32 and no ARM hardware can run AArch64.

Daniel Sanders 09c8f6f6a4 [Compiler-rt][MIPS][Profile] Adding support for MIPS32/64
Summary:
Changed cmake/config-ix.cmake to add support for different MIPS architectures: mips, mipsel, mips64, mips64el
In profile code there is no target  based dependencies, so just enabling mips flag does the work.

Evgeniy Stepanov 0f7ab59adc [sanitizer] Add i686 arch to compiler-rt.
This is needed so we can produce -i686- named libraries for
x86 Android (which is i686-linux-android).

An alternative solution would be keeping the "i386" name internally and
tweaking the OUTPUT_NAME of compiler-rt libraries.

Evgeniy Stepanov 9e922e7d24 [sanitizer] Android build cleanup.
* Detect Android toolchain target arch and set correct runtime library name.
* Merged a lot of Android and non-Android code paths.
* Android is only supported in standalone build of compiler-rt now.
* Linking lsan-common in ASan-Android (makes lsan annotations work).
* Relying on -fsanitize=address linker flag when building tests (again,
  unification with non-Android path).
* Runtime library moved from lib/asan to lib/linux.

sanitizer_stacktrace.cc: Program counter for MIPS32 is four byte aligned
and a delay slot so subtracted PC by 8 for getting call site address.
cast-overflow.cpp: Added big endian support for this test case.

Ehsan Akhgari 045423f26d Fix a mistake in r217762
Summary:
The extra macro definition needs to go into COMPILER_RT_GTEST_CFLAGS
in order to be used for gtests on MSVC2012.

Test Plan: This is part of the fixes necessary for the ASAN tests to pass with MSVC2012.
