Michal Gorny 34ca7168ae [cmake] Remove i686 target that is duplicate to i386
Remove the explicit i686 target that is completely duplicate to
the i386 target, with the latter being used more commonly.

1. The runtime built for i686 will be identical to the one built for
i386.

2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion
on the clang end which has to expect either of them.

3. The checks are based on wrong assumption that __i686__ is defined for
all newer x86 CPUs. In fact, it is only declared when -march=i686 is
explicitly used. It is not available when a more specific (or newer)
-march is used.

Curious enough, if CFLAGS contain -march=i686, the runtime will be built
both for i386 and i686. For any other value, only i386 variant will be
built.

despite the fact that false negative ratio might be huge (up to 85%). This happens for big real world applications
that may contain random binary data (e.g. browser), but for smaller apps situation is not so terrible and LSan still might be useful.

Kostya Kortchinsky b39dff4551 [scudo] Refactor of CRC32 and ARM runtime CRC32 detection
Summary:
ARM & AArch64 runtime detection for hardware support of CRC32 has been added
via check of the AT_HWVAL auxiliary vector.

Following Michal's suggestions in D28417, the CRC32 code has been further
changed and looks better now. When compiled with full relro (which is strongly
suggested to benefit from additional hardening), the weak symbol for
computeHardwareCRC32 is read-only and the assembly generated is fairly clean
and straight forward. As suggested, an additional optimization is to skip
the runtime check if SSE 4.2 has been enabled globally, as opposed to only
for scudo_crc32.cpp.

scudo_crc32.h has no purpose anymore and was removed.

Kostya Kortchinsky c4d6c938e3 [scudo] Separate hardware CRC32 routines
Summary:
As raised in D28304, enabling SSE 4.2 for the whole Scudo tree leads to the
emission of SSE 4.2 instructions everywhere, while the runtime checks only
applied to the CRC32 computing function.

This patch separates the CRC32 function taking advantage of the hardware into
its own file, and only enabled -msse4.2 for that file, if detected to be
supported by the compiler.

Another consequence of removing SSE4.2 globally is realizing that memcpy were
not being optimized, which turned out to be due to the -fno-builtin in
SANITIZER_COMMON_CFLAGS. So we now explicitely enable builtins for Scudo.

The resulting assembly looks good, with some CALLs are introduced instead of
the CRC32 code being inlined.

Michal Gorny c74123bdff [cmake] Disable appending -msse4.2 flag implicitly
Disable the code appending -msse4.2 flag implicitly when the compiler
supports it. The compiler support for this flags do not indicate that
the underlying CPU will support SSE4.2, and passing it may result in
SSE4.2 code being emitted *implicitly*.

If the target platform supports SSE4.2 appropriately, the relevant bits
should be already enabled via -march= or equivalent. In this case
passing -msse4.2 is redundant.

If a runtime detection is desired (which seems to be a case with SCUDO),
then (as gcc manpage points out) the specific SSE4.2 needs to be
isolated into a separate file, the -msse4.2 flag can be forced only
for that file and the function defined in that file can only be called
when the CPU is determined to support SSE4.2.

This fixes SIGILL on SCUDO when it is compiled using gcc-5.4.

Kostya Kortchinsky 1148dc5274 [scudo] 32-bit and hardware agnostic support
Summary:
This update introduces i386 support for the Scudo Hardened Allocator, and
offers software alternatives for functions that used to require hardware
specific instruction sets. This should make porting to new architectures
easier.

Among the changes:
- The chunk header has been changed to accomodate the size limitations
  encountered on 32-bit architectures. We now fit everything in 64-bit. This
  was achieved by storing the amount of unused bytes in an allocation rather
  than the size itself, as one can be deduced from the other with the help
  of the GetActuallyAllocatedSize function. As it turns out, this header can
  be used for both 64 and 32 bit, and as such we dropped the requirement for
  the 128-bit compare and exchange instruction support (cmpxchg16b).
- Add 32-bit support for the checksum and the PRNG functions: if the SSE 4.2
  instruction set is supported, use the 32-bit CRC32 instruction, and in the
  XorShift128, use a 32-bit based state instead of 64-bit.
- Add software support for CRC32: if SSE 4.2 is not supported, fallback on a
  software implementation.
- Modify tests that were not 32-bit compliant, and expand them to cover more
  allocation and alignment sizes. The random shuffle test has been deactivated
  for linux-i386 & linux-i686 as the 32-bit sanitizer allocator doesn't
  currently randomize chunks.

Kuba Mracek ff1bd20ded [sanitizer] Add macOS minimum deployment target to all compiler invocations in lit tests
The Clang driver on macOS decides the deployment target based on various things, like your host OS version, the SDK version and some environment variables, which makes lit tests pass or fail based on your environment. Let's make sure we run all lit tests with `-mmacosx-version-min=${SANITIZER_MIN_OSX_VERSION}` (10.9 unless overriden).

Currently, when doing a ASanified build of LLVM (with Clang, compiler-rt and libcxx) via -DLLVM_USE_SANITIZER=Address and not using any other options, we already disable building of sanitizer runtimes (because they themselves can’t be sanitized) and also exclude the sanitizer tests. However, the same is not done for the profiling runtime, which will build fine, but then all the tests fail due to linking errors. Let’s disable the profiling runtime as well (when LLVM_USE_SANITIZER is set).

`COMPILER_RT_BUILD_SANITIZERS` which only gives an all or nothing control.

Summary:
This is a fixed-up version of D21612, to address failure identified post-commit.

Original commit description:

This patch implements the initialisation and patching routines for the XRay runtime, along with the necessary trampolines for function entry/exit handling. For now we only define the basic hooks for allowing an implementation to define a handler that gets run on function entry/exit. We expose a minimal API for controlling the behaviour of the runtime (patching, cleanup, and setting the handler to invoke when instrumenting).

Fixes include:
- Gating XRay build to only Linux x86_64 and with the right dependencies in case it is the only library being built
- Including <cstddef> to fix std::size_t issue

- warning C4005: 'FILE_MAP_EXECUTE': macro redefinition

- InstrProfilingWriter.c(275): warning C4221: nonstandard extension used: 'Data': cannot be initialized using address of automatic variable 'Zeroes'

Turn this warning off. This is definitely legal in C++, all compilers
accept it, and I only have room for half of one language standard in my

- InstrProfilingMerge.c.obj : warning LNK4006: _VPMergeHook already defined in InstrProfilingMergeFile.c.obj; second definition ignored

Summary:
This is an initial implementation of a Hardened Allocator based on Sanitizer Common's CombinedAllocator.
It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast.
The following were implemented:
- additional consistency checks on the allocation function parameters and on the heap chunks;
- use of checksum protected chunk header, to detect corruption;
- randomness to the allocator base;
- delayed freelist (quarantine), to mitigate use after free and overall determinism.
Additional mitigations are in the works.

Summary:
This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake.

This patch contains the following specific changes:

* Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake
* Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake
* Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration

I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64.

This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.

This test requires llvm-symbolizer to be able to convert a stack

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.

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.

Hi, this patch adds a CMake flag called `COMPILER_RT_ENABLE_TSAN_OSX`, which is off by default. If enabled, the build system will be building the OS X version of the TSan runtime library (called `libclang_rt.tsan_osx_dynamic.dylib`). I'll submit patches that fix OS X build errors shortly.

This is part of an effort to port TSan to OS X, and it's one the very first steps. Don't expect TSan on OS X to actually work or pass tests at this point.

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.

0000 4000 00 - 0200 0000 00: main binary
2000 0000 00 - 4000 0000 00: shadow memory
4000 0000 00 - 5000 0000 00: metainfo
5000 0000 00 - 6000 0000 00: -
6000 0000 00 - 6200 0000 00: traces
6200 0000 00 - 7d00 0000 00: -
7d00 0000 00 - 7e00 0000 00: heap
7e00 0000 00 - 7fff ffff ff: modules and main thread stack

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
   no support to make mmap page non-executable.

 * longjmp tests due missing specialized assembly routines.

These tests are xfail for now.

The only tsan issue still showing is:

  rtl/TsanRtlTest/Posix.ThreadLocalAccesses

Which still required further investigation.  The test is disable for
aarch64 for now.

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).

It also XFAIL static_tls test for aarch64 linker may omit the __tls_get_addr call

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'.

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.

Alexey Samsonov 969902b43b [ASan] Always build shared ASan runtime on Linux.
This commit changes the strategy for building shared ASan runtime
and the way we test it:
  - 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.

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.

Petar Jovanovic c2e0427b94 [UBSan] Adding support of MIPS32
Changed files: 
config-ix.cmake: Enabled UBSan for MIPS32
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.

Patch by Sagar Thakur.
