environment, the unit tests fail to link. This patch does the following changes
>Rename COMPILER_RT_TEST_CFLAGS to COMPILER_RT_UNITTEST_CFLAGS to reflect the
way it's used.
>Add COMPILER_RT_TEST_COMPILER_CFLAGS to COMPILER_RT_UNITTEST_CFLAGS so that
cross-compiler would be able to build/compile the unit tests
>Add COMPILER_RT_UNITTEST_LINKFLAGS to COMPILER_RT_UNITTEST_CFLAGS so that
cross-compiler would be able to link the unit tests (if needed)

Summary:
* Refactored the iOS config-ix.cmake code to be a more compact loop over supported embedded platforms.
* Added watchOS and tvOS as experimental platforms, they don't currently build so they are disabled by default

llvmBufferWriter and a few related symbols were missing from libclang_rt
on Darwin (PR26002). This should fix the problem.

Summary: This change configures Windows builds to build the complier-rt profile support library (clang_rt.profile-i386.lib). Windows API incompatibilities in the compiler-rt profile lib are also fixed.

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
to enable the tests and fix the pagesize debug check by getting its
value at runtime (since aarch64 has multiple pagesize depending of
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.

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"

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.

* Adds COMPILER_RT_EXTERNALIZE_DEBUGINFO option
* On Darwin this results in calling dsymutil and strip after linking
* This generates an error on non-darwin platforms, matching the LLVM behavior

For OS X builds of compiler-rt, we run `darwin_test_archs` to determine which architectures can the toolchain target. This detection takes quite a long time, and the result is always the same (as long as you don't upgrade your OS, system headers or toolchain). Let's cache the result.

If the top-level cmake has a custom make specified through -DCMAKE_MAKE_PROGRAM
then this must be passed along to the sub-build processes in compiler-rt or the
build process will fail.

Apparently check_c_compiler_flag isn't a thing everywhere. Not being
incredibly well-versed in cmake, I'm hoping that check_cxx_compiler_flag
serves a similar purpose. :)

Turns out that there are some checks in the backend that change code generation for armv7 if you are building against an iOS sys root. For the macho_embedded builtins we really don't want that.
llvm-svn: 253064
We need to add -fPIC to the flags for the builtins in case PIC was turned off at a higher level. We also want to set ENABLE_PIC to Off when building the macho_embedded builtins so the top-level settings don't impact that build.

Setting CMAKE_*_FLAGS isn't sufficient here because CMAKE_*_FLAGS_${CMAKE_BUILD_TYPE} can override the flags, and there is no way to safely clear that because it is a cached variable (<sarcasm> YAY! </sarcasm>).
llvm-svn: 252807
* Setting CMAKE_*_FLAGS_${BUILD_TYPE} isn't really needed since we're setting the same value everywhere
* functions sanitize variables differently from macros, darwin_add_embedded_builtin_libraries should be a macro otherwise it won't alter the variables.

This commit reverts r252525. I was not really thinking about this fix properly. This doesn't work because it relys on try_compile checks which do a full compile & link. I'm going to put in a temporary solution as an interm step until we have a way to perform compiler checks without linking.

Not making sure there are thin libraries results in some difficult to diagnose build failures. This check should make those build failures go away.

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.

This patch add support for leak sanitizer for aarch64. Similar to
MIPS it uses a SizeClassAllocator32 due VMA constraints (aarch64
currently supports 39 and 42-bit VMA).
It also fixes the android build issue.
