Reid Kleckner 652d70f3e1 Fix most MSVC warnings in compiler-rt profiling library
Here's the warnings and how they were fixed:

- InstrProfilingUtil.c(110): warning C4013: '_open_osfhandle' undefined; assuming extern returning int

Include io.h to get the prototype.

- warning C4005: 'FILE_MAP_EXECUTE': macro redefinition

Stop trying to support pre-XP versions of Windows, don't attempt to
define this macro.

- InstrProfilingWriter.c(271): warning C4221: nonstandard extension used: 'Data': cannot be initialized using address of automatic variable 'Header'
- 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
brain.

- InstrProfilingValue.c(320): warning C4113: 'uint32_t (__cdecl *)()' differs in parameter lists from 'uint32_t (__cdecl *)(void)'

Fix this with an explicit (void) in the prototype.

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

Last remaining warning. This is from linking a selectany definition with
a strong definition. We need to sort out weak symbols in compiler-rt in
general, though.

Kostya Serebryany 712fc9803a [sanitizer] Initial implementation of a Hardened Allocator
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.

Chris Bieneman 648d3bc8c7 [CMake] detect_target_arch needs to be moved to Utils
This macro is called from the base config, so it can't live in config-ix, it needs to be in the utils. I suspect the only reason this hasn't caused problems is that nobody is building the Android builtins from the builtins subdirectory.

Etienne Bergeron 00f3f6e296 This patch is activating the build of Asan on Windows 64-bits.
It's fixing compilation errors. The runtime is not yet working.

Missing features:

OverrideFunction for x64
an equiv function for inline asm (atomic_compare_exchange_strong)
shadow memory offset needs to be adjusted
RoundUpToInstrBoundary for x64
They will be implemented by subsequent patches.

Patch by Wei Wang.

Etienne Bergeron 3df2879232 [compiler-rt] Fix multi-configuration output paths
Summary:
When using a multi-configuration build (i.e. MSVC) the output path where
libraries are dropped is incorrect.

Example:
```
C:\src\llvm\examples>d:\src\llvm\build\Release\bin\clang-cl.exe -fsanitize=address test.cc
LINK : fatal error LNK1181: cannot open input file 'd:\src\llvm\build\Release\bin\..\lib\clang\3.9.0\lib\windows\clang_rt.asan-i386.lib'
```

The dropped executable path contains the configuration 'Release':
```
'd:\src\llvm\build\Release\bin\..\lib\clang\3.9.0\lib\windows\Release\clang_rt.asan-i386.lib'
```


The variable 'RUNTIME_OUTPUT_DIRECTORY' is used to specify the output directory.
But CMAKE is appending the current configuration (i.e. Debug, Release).

see: https://cmake.org/cmake/help/v3.0/prop_tgt/RUNTIME_OUTPUT_DIRECTORY.html
```
"Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the specified directory."
```

To avoid this problem, the configuration specific variable must be set:
'RUNTIME_OUTPUT_DIRECTORY_DEBUG', 'RUNTIME_OUTPUT_DIRECTORY_RELEASE', and so on.

Chris Bieneman c49e5e336b [CMake] Support platform building builtins without a full toolchain
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.

Chris Bieneman aa3d2c13bf [CMake] NFC. Add support for testing the compiler without testing the linker
Summary:
One of the big limitations we have in the compiler-rt build system today is that we cannot bootstrap building the builtins because you need a fully functional toolchain to pass CMake's tests.

This change adds support for compile only tests.

It is NFC because nothing is using the compile-only tests yet.

I believe this is the last separable part of D16653.

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.

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.

Patch discussion at reviews.llvm.org/D12841.

not mix and matched.  We now built the appropriate named archive so that we can

Chris Bieneman 0d427986f5 [CMake] [Darwin] Bug 21562 - Add a CMake equivalent for make/platform/clang_darwin.mk in compiler_rt
Summary:
Building the builtins on Darwin platforms is a bit complicated. This is a first-pass implementation of the functionality from clang_darwin.mk into CMake.

When building the builtins on Darwin we have layers of blacklists that we apply based on platform, architecture, and minimum supported OS version.

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.

Alexey Samsonov 63eaeca7d0 [CMake] Remove all uses of LLVM_NATIVE_ARCH.
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.

This doesn't change the behavior in the default build configuration.

Chris Bieneman b38affa474 [CMake] Fix building builtins on Linux and Darwin.
Summary:
I broke building the builtins with r245967. This fixes them on Linux and builds them properly for Darwin.

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.

Adhemerval Zanella 15db6dc2fb [compiler-rt] [tsan] Enable TSan for AArch64/42-bit VMA
This patch adds support for tsan on aarch64-linux with 42-bit VMA
(current default config for 64K pagesize kernels).  The support is
enabled by defining the SANITIZER_AARCH64_VMA to 42 at build time
for both clang/llvm and compiler-rt.  The default VMA is 39 bits.

It also enabled tsan for previous supported VMA (39).

Changes to CMakeLists files are all minimal except ubsan which tests the new ARCHS loop.

Further cleanup patches will follow.

Chris Bieneman d160260681 [CMake] merge add_compiler_rt_runtime and add_compiler_rt_darwin_runtime into a single function
Summary: This refactoring moves much of the Apple-specific behavior into a function in AddCompilerRT. The next cleanup patch will remove more of the if(APPLE) checks in the outlying CMakeLists.

This patch adds a bunch of new functionality to add_compiler_rt_runtime so that the target names don't need to be reconstructed outside the call. It also updates some of the call sites to exercise the new functionality, but does not update all uses fully. Subsequent patches will further update call sites and move to using the new features.

Chris Bieneman 5eae197ab0 [CMake] Fix building unit tests on Darwin
Summary:
There are a number of issues with unit tests on Darwin. These patches address the following:
* Unit tests should be passed -arch (-m32/-m64 isn't sufficient)
* 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).

Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.

Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.

This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.
