This way it gets picked up for all sanitizer libs, both sanitizer_common
and asan.  I believe those are the only libs that build with asan.
There should be no need to set the __func__ definition inside
clang_compile.

For now, use both keywords, INTERFACE and PRIVATE via the variable,
  - ${cmake_2_8_12_INTERFACE}
  - ${cmake_2_8_12_PRIVATE}

They could be cleaned up when we introduce 2.8.12.

[CMake] Better support for COMPILER_RT_ENABLE_WERROR. Make sure compiler-rt libraries are build by 'make all' command

1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to
get necessary LLVM source/binary directories.
2) Add basic support for running lit tests (check-xsan commands).
For now this "support" is far from what we want:
  * unit tests are not built currently.
  * lit tests use Clang/compiler-rt from LLVM build directory,
    not the host compiler or just-built compiler-rt libraries.

We should make a choice on the way we intend ti run compiler-rt lit testsuite:
a) use either Clang from LLVM build tree, or the host compiler.
b) use either just-built runtimes, or the runtimes shipped with the
host compiler.

Using just-built runtimes is tricky - we have to know where to put them, so that
Clang/GCC driver would pick them up (and not overwrite the existing runtimes).
Using a host compiler instead of Clang from LLVM build tree will give us a chance to
run lit tests under GCC (which already has support for several sanitizers).

That is, I tend to make the following choice: if we're in a standalone compiler-rt
build, use host compiler with its set of runtime libraries to run lit tests.
This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in
a standalone build - the latter wouldn't invoke the former. Note that if we decide
to fix LLVM/Clang/compiler-rt build system so that it would configure/build
compiler-rt with just-built Clang (as we do in Makefile-based build), this will not
be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt
before running compiler-rt tests.

This change allows to build compiler-rt libraries separately from
LLVM/Clang (path to LLVM build directory should be specified at
configure time). Running tests is not yet supported.

This change replaces 32- and 64- bit config.in-s with a single config template
that is used to generate both 32 and 64 bits configs as well as the new
arm-android config. Arm-android config is special because it can run tests on
a remote device over adb (android debug bridge). 

We replace %clang with a script that run the compiler, upload the result to
the device, and replaces it with another script. The second script runs the
binary on the device and delivers stdout/stderr/exitcode back.

If the -fno-function-sections flag isn't recognized, the compiler
emits a warning. This isn't enough to cause the check to fail, so we
enable -Werror as well.

-fno-function-sections is broken in Clang.

llvm-svn: 200684

It breaks when a binary is linked with --gc-sections: parts of sanitizer
interface get thrown away and inaccessible from dlopen-ed libs.

Remove /FS as it's auto-added by CMake 2.8.12.1; also, remove /wd4221 as 4221 is a linker warning, not a compiler warning

Adding the ARM RT sources to the CMake files, and enabling some
sanitizers to also build on ARM. This is far from supported or
production quality, but enabling it to build will get us errors
that we can actually fix.

Having said that, the Compiler-RT and the Asan libraries are
know to work on some variations of ARM.

(-Wl,-syslibroot was accidentally overridden by -isysroot from Clang on OSX 10.9)

-isysroot is a Clang/LLVM-GCC-specific option, but hosting libsanitizer for LLVM
with GCC on Darwin shouldn't work anyway, because of the missing blocks support.

llvm-svn: 195132

Summary:
Definitions we use in public sanitizer headers may
slightly conflict with the ones we use in private sanitizer runtimes.
Moreover, we generally forbid to include any system headers (like <stdint.h>)
in sanitizer runtime headers. This leads to inevitable duplication of selected
interface function declarations, but we decided to live with it.

CMake changes to build the ASan runtime for the iOS simulator. This is a universal library targeting the same architectures as the OSX ASan runtime does, thus the iossim version can't live in the same universal libclang_rt.asan_osx_dynamic.dylib

The difference between the OSX and iossim builds is in the -mios-simulator-version-min and -ios_simulator_version_min flags that tell Clang to compile and link iossim code.

The iossim runtime can only be built on a machine with both Xcode and the iOS Simulator SDK installed. If xcodebuild -version -sdk iphonesimulator Path returns a nonempty path, it is used when compiling and linking the iossim runtime.
