and x86_64h-apple.
Mark the test as UNSUPPORTED to fix a bot that is failing.
http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_check
The bot is failing because asan_symbolize.py cannot tell whether the
reported address is from an x86_64 slice or an x86_64h slice by the
length of the address alone, so it ends up passing the wrong arch to
atos.

Summary:
Since we can now build the builtins without a full toolchain these files should no longer be needed.
This is the last vestige of autoconf!

Summary:
This does not actually fixes the test.
AddressSanitizer::OOB_char behavior is inconsistent but it somehow usually
works. On arm it runs more iterations than expected. And adding a new test with AddressSanitizerInterface prefix, even empty, somehow breaks OOB_char test.
So I will rename my test to make the bot green and will continue to investigate the test.

Summary:
On apple targets, when SANITIZER_CAN_USE_CXXABI is false,
the ubsan cxxabi sources aren't built, since they're unused.
Do this on non-apple targets as well.
This fixes errors when linking sanitizers if c++ abi is
unavailable.

This should resolve PR23162. This patch has two parts.
First we need to check the error code from xcodebuild when querying for SDKs, second if the OS X SDK is not discovered, we ensure that /usr/include exists and use / as the OS X sysroot.

Durning standalone builds (which includes runtimes builds) we want to create a target named check-compiler-rt. Additionally we also create check-all if it doesn't already exist as a convienence target that depends on check-compiler-rt.
This allows us to generate a single check target that invokes lit for all test suites in the runtimes projects, while avoiding name collision of check-all and not breaking existing workflows.

This is a wrapper target of all the component install targets. This wrapper target will be used by the new LLVM runtimes directory to connect top-level targets to the runtime project target.

Introduce a new CMake option `COMPILER_RT_SANITIZERS_TO_BUILD` which takes
either a special token `all` (default) which will preserve the current behaviour
or a CMake list of sanitizers to build. It will still perform the normal checks
if the sanitizer is requested. It only permits a further means to exclude a
particular sanitizer. This gives finer grained control than
`COMPILER_RT_BUILD_SANITIZERS` which only gives an all or nothing control.

When compiler-rt's CMake is not directly invoked, it will currently not call
project() and thus ASM will not be enabled.
We also don't need to put the .S files through the C compiler then.

Summary:
test/builtins/Unit/cpu_model_test.c tests the X86 specific builtin `__builtin_cpu_supports`.
It fails if the clang's default target is not X86.
The proposed patch adds an additional requirement for the X86 target to the test, making lit ignore the test if the target is different.

Clang added warning that taking the address of a packed struct member
possibly yields an unaligned pointer. This case is benign because
the pointer gets casted to an uptr and not used for unaligned accesses.
Add an intermediate cast to char* until this warning is improved (see
also https://reviews.llvm.org/D20561)
