Dean Michael Berris 938c5031ab [compiler-rt][XRay] re-submitting r276117, with fixes for build breakage due to extraneous and missing dependencies and attempts to build on unsupported OSes
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

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.

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

Douglas Katzman c4ffd48aba Let cmake infer source file language by the file extension.
This applies default compiler flags to .S files, in particular removing
the "-pedantic" option, which is desirable because there is nothing to
reasonably warn about; and the only thing that gcc warns about is that
you allegedly can't correctly invoke GLUE2 in lib/builtins/assembly.h
on platforms for which USER_LABEL_PREFIX is the empty string.

In the gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=33305 that
added the warning, a commenter notes that giving a macro of zero characters
to another macro is not precisely the same as failing to supply an argument,
and "there is a widespread belief in C++ community that such usage is valid".
Unfortunately the only way to silence the warning is to avoid -pedantic.

Reid Kleckner aa9029691f Silence some CMake 3.3 dev warnings in compiler-rt
Fix a trivial instance of CMP0054 that came up on llvmdev.

The other warnings were CMP0057, which is about using the same file as a
MAIN_DEPENDENCY multiple times.  The old behavior hasn't been a problem
yet, so I silenced the warning and filed PR23595 to document the issue
if someone cares.

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.

Alexey Samsonov aa980c760b [CMake] Add the way to run tests in standalone build.
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.

Alexey Samsonov de4ef2a066 [CMake] Rudimentary support for standalone CompilerRT build system.
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.

Evgeniy Stepanov aa9d74cc5d [asan] Android test runner for ASan lit tests.
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.
