Matt Morehouse f051f5d1e6 Integrate Kostya's clang-proto-fuzzer with LLVM.
Summary:
The clang-proto-fuzzer models a subset of C++ as a protobuf and
uses libprotobuf-mutator to generate interesting mutations of C++
programs.  Clang-proto-fuzzer has already found several bugs in
Clang (e.g., https://bugs.llvm.org/show_bug.cgi?id=33747,
https://bugs.llvm.org/show_bug.cgi?id=33749).

As with clang-fuzzer, clang-proto-fuzzer requires the following
cmake flags:
- CMAKE_C_COMPILER=clang
- CMAKE_CXX_COMPILER=clang++
- LLVM_USE_SANITIZE_COVERAGE=YES  // needed for libFuzzer
- LLVM_USE_SANITIZER=Address  // needed for libFuzzer

In addition, clang-proto-fuzzer requires:
- CLANG_ENABLE_PROTO_FUZZER=ON

clang-proto-fuzzer also requires the following dependencies:
- binutils  // needed for libprotobuf-mutator
- liblzma-dev  // needed for libprotobuf-mutator
- libz-dev  // needed for libprotobuf-mutator
- docbook2x  // needed for libprotobuf-mutator
- Recent version of protobuf [3.3.0 is known to work]

A working version of libprotobuf-mutator will automatically be
downloaded and built as an external project.

Implementation of clang-proto-fuzzer provided by Kostya
Serebryany.

Chris Bieneman 6b5851bb4a [CMake] NFC. Add clang-tablegen-targets utility target
By creating this target other projects that depend on clang-generated headers (like LLDB) will no longer be order-dependent on Clang being processed by CMake first.

Also, by creating a dummy of this target in ClangConfig.cmake, projects that can build against out-of-tree clang can freely depend on the target without needing to have conditionals for if clang is in-tree or out-of-tree.

David L. Jones 2f7545228d Simplify Clang's version number configuration in CMake.
Currently, the Clang version is computed as follows:

 1. LLVM defines major, minor, and patch versions, all statically set. Today,
    these are 4, 0, and 0, respectively.
 2. The static version numbers are combined into PACKAGE_VERSION along with a
    suffix, so the result today looks like "4.0.0svn".
 3. Clang extracts CLANG_VERSION from PACKAGE_VERSION using a regexp. The regexp
    allows the patch level to omitted, and drops any non-digit trailing values.
    Today, this result looks like "4.0.0".
 4. CLANG_VERSION is then split further into CLANG_VERSION_MAJOR and
    CLANG_VERSION_MINOR. Today, these resolve to 4 and 0, respectively.
 5. If CLANG_VERSION matches a regexp with three version components, then
    CLANG_VERSION_PATCHLEVEL is extracted and the CLANG_HAS_VERSION_PATCHLEVEL
    variable is set to 1. Today, these values are 0 and 1, respectively.
 6. The CLANG_VERSION_* variables (and CLANG_HAS_VERSION_PATCHLEVEL) are
    configured into [llvm/tools/clang/]include/clang/Basic/Version.inc
    verbatim by CMake.
 7. In [llvm/tools/clang/]include/clang/Basic/Version.h, macros are defined
    conditionally, based on CLANG_HAS_VERSION_PATCHLEVEL, to compute
    CLANG_VERSION_STRING as either a two- or three-level version number. Today,
    this value is "4.0.0", because despite the patchlevel being 0, it was
    matched by regexp and is thus "HAS"ed by the preprocessor. This string is
    then used wherever Clang's "version" is needed [*].

[*] Including, notably, by compiler-rt, for computing its installation path.

This change collapses steps 2-5 by defaulting Clang to use LLVM's (non-string)
version components for the Clang version (see [*] for why not PACKAGE_VERSION),
and collapses steps 6 and 7 by simply writing CLANG_VERSION_STRING into
Version.inc. The Clang version today always uses the patchlevel form, so the
collapsed Version.inc does not have logic for a version without a patch level.

Historically speaking, this technique began with the VER file in r82085 (which
survives in the form of the regexp in #3). The major, minor, and patchlevel
versions were introduced by r106863 (which remains in #4-6). The VER file itself
was deleted in favor of the LLVM version number in r106914. On the LLVM side,
the individual LLVM_VERSION_MAJOR, LLVM_VERSION_MINOR, and PACKAGE_VERSION
weren't introduced for nearly two more years, until r150405.

Chris Bieneman a1aa4069d9 [CMake] Workflow improvements to PGO generation
This patch adds a few new convenience options used by the PGO CMake cache to setup options on bootstrap stages. The new options are:

PGO_INSTRUMENT_LTO - Builds the instrumented and final builds with LTO
PGO_BUILD_CONFIGURATION - Accepts a CMake cache script that can be used for complex configuration of the stage2-instrumented and stage2 builds.

The patch also includes a fix for bootstrap dependencies so that the instrumented LTO tools don't get used when building the final stage, and it adds distribution targets to the passthrough.

Jonas Hahnfeld d196fa524f Support setting default value for -rtlib at build time
This patch introduces a new cmake variable: CLANG_DEFAULT_RTLIB, thru
which we can specify a default value for -rtlib (libgcc or

stdlib thru CLANG_DEFAULT_CXX_STDLIB.

With these two options, we can configure clang to build binaries on
Linux that have no runtime dependence on any gcc libs (libstdc++ or
libgcc_s).

Chris Bieneman d052efc332 [CMake] Pass DYLD_LIBRARY_PATH as CMake variable instead of as envar

Chris Bieneman c486541fea [CMake] Cleaning up some CMake warnings
In Bootstrap builds Clang logs some warnings. These are caused because Clang passes CLANG_STAGE and BOOTSTRAP_DEFAULT_PASSTHROUGH into the next stage's configuration.

BOOTSTRAP_DEFAULT_PASSTHROUGH shouldn't be passed, so it is renamed to _BOOTSTRAP_DEFAULT_PASSTHROUGH, to prevent passthrough.

CLANG_STAGE should be passed, so I've changed the code to log it if it is set outside the if(CLANG_ENABLE_BOOTSTRAP) block. This makes the variable always used, so the warning goes away.

Chris Bieneman 38238a4f56 [CMake] Remove CLANG_APPEND_VC_REV option
I added this option in r257827 to try and add compatibility with autoconf. At the time I misunderstood the problem.

Our CMake automatically generates the SVN revision information and generates a build action to update it so builds don't need to be re-configured on SCM update (which is a better solution than we had in autoconf).

The problem I was actually seeing was isolated cases where SVN revision information isn't available because the repository structures have been removed. This happens in some automated testing systems.

This patch allows SVN_REVISION to be overridden if the build configuration could not find the SCM repository structures, and removes the code from my original patch because it is unnecessary.

Chris Bieneman 834a40b463 [Perf-Training] Reworked workflow improvements for order-file generation
This is re-landing r260742. I've reworked the conditionals so that it only hits when targeting Apple platforms with ld64.

Original Summary:
With this change generating clang order files using dtrace uses the following workflow:

cmake <whatever options you want>

ninja generate-order-file

ninja clang

This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.

CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.
