Philip Pfaffe bbb86719c1 [Polly][CMake] Exclude isl_config from the polly-check-format target.
Summary:
The custom `polly-check-format` target runs clang-format over all source files in the directory tree excluding lib/External. `isl_config.h` is a header file that is generated by CMake in the build directory, and it's not correctly formatted (which I also wouldn't consider necessary, as it is a generated file).

If the build directory is actually inside the Polly source directory (which it might be if you're building Polly out-of-tree), that check always fails. Hence this patch excludes this file from the check-format target.

Siddharth Bhat 17f01968f1 [Polly] Added OpenCL Runtime to GPURuntime Library for GPGPU CodeGen
Summary:
When compiling for GPU, one can now choose to compile for OpenCL or CUDA,
with the corresponding polly-gpu-runtime flag (libopencl / libcudart). The
GPURuntime library (GPUJIT) has been extended with the OpenCL Runtime library
for that purpose, correctly choosing the corresponding library calls to the
option chosen when compiling (via different initialization calls).

Additionally, a specific GPU Target architecture can now be chosen with -polly-gpu-arch (only nvptx64 implemented thus far).

Michael Kruse 792a6fcc57 [CMake] Use object library to build the two flavours of Polly.
Polly comes in two library flavors: One loadable module to use the
LLVM framework -load mechanism, and another one that host applications
can link to. These have very different requirements for Polly's
own dependencies.

The loadable module assumes that all its LLVM dependencies are already
available in the address space of the host application, and is not allowed
to bring in its own copy of any LLVM library (including the NVPTX
backend in case of Polly-ACC).

The non-module library is intended to be linked to using
target_link_libraries. CMake would then resolve all of its dependencies,
including NVPTX and ensure that only a single instance of each library
will be used.

Michael Kruse abf05b18db [CMake] Fix polly-isl-test execution in out-of-LLVM-tree builds.
The isl unittest modified its PATH variable to point to the LLVM bin dir.
When building out-of-LLVM-tree, it does not contain the
polly-isl-test executable, hence the test fails.

Ensure that the polly-isl-test is written to a bin directory in the
build root, just like it would happen in an inside-LLVM build.
Then, change PATH to include that dir such that the executable in it
is prioritized before any other location.

Michael Kruse 9c19d1f3aa [CMake] Fix unittests in out-of-LLVM-tree builds.
Unittests are linked against a subset of LLVM libraries and its
transitive dependencies resolved by CMake. The information about indirect
library dependency is not available when building separately from
LLVM, which result in missing symbol errors while linking.

Resolve this issue by querying llvm-config about the available
LLVM libraries and link against all of them, since dependence
information is still not available.

opportunity to verify that GPU_CODEGEN tests are only run if GPU code generation
has been enabled in cmake.

Michael Kruse 519b3cfd27 Compile ISL into its own library
Refactor all ISL-related cmake build instructions into its own 
CMakeLists.txt and build as a separate library.

This is useful to apply ISL-related build flags to ISL only and not to

Proposed name of the library is Polly_isl. It is not "isl" to avoid 
mix-up with potentially installed libisl.{a|so}.

- Windows with cmake 3.2
- Ubuntu with cmake 3.0.2 
- Ubuntu with cmake 3.0.2  BUILD_SHARED_LIBS on

Michael Kruse 69f3788c36 Revise polly-{update|check}-format targets
Summary:
Make clang-format run on each file independently using
add_custom_format (instead using a shell script in utils/). The targets
polly-{update|check}-format depend on these.

The primary motivation is to make them work on Windows, but also
improves them generally:
- Each file update/check can run in parallel (Although they do not take
  long to run anyway)
- Implicit dependency on clang-format, so it recompiles if necessary
- polly-check-format shows the formatting difference if failing

Michael Kruse 84bf8a3bc4 Introspect llvm-config --assertion-mode in cmake out-of-tree builds
When compiling Polly without LLVM sources but with system-installed
LLVM, the build process would not honor the LLVM_ENABLE_ASSERTIONS
setting LLVM was compiled with, but effectively assume that it is
switched off when compiling. During unit-tests llvm-lit would still
query the LLVM_ENABLE_ASSERTIONS flag and enable tests which require
assertions. Even if enabled for LLVM, Polly does not output its debug
info and statistics in this this mode such that 7 tests fail.

To fix, we query llvm-config --assertion-mode and if on, enable
assertions as HandleLLVMOptions.cmake would do.

We cannot reliably use HandleLLVMOptions.cmake itself as the host's
LLVM build might have been built using automake and distributions
change file locations (e.g. Debian to
/usr/share/llvm-${VERSION}/cmake/HandleLLVMOptions.cmake).

Michael Kruse ee512e58a3 Prepare replacing ISL by its 'make dist' files
Currently the Polly repository contains the ISL sources with bogus
isl_config.h and gitversion.h. This is problematic. In this state a
 macro

    #define __attribute__(x)

becomes active in the source, leading to various problems e.g. when
included before system header files. This patch will instead generate
the two files specific to the host system at configure-time.

For CMake, we replicate the tests that ISL's configure performs using
try_compile(). In autotools build, we just invoke ISL's configure to
generate the two files. This consequently required regenerating
autoconf/configure.

'make dist' distributions of ISL contain a file GIT_HEAD_ID which
contains the version the distribution is derived from. The repository
files themselves do not contain such a hint. In a later commit we will
replace the isl directory by the contents of such a .tar.gz. It does
not contain the files imdrover.c iprime.c pi.c and rsamath.c currently
compiled into Polly, but not used and therefore are removed by this
patch.

In the long term we plan to generate a dedicated library for ISL instead
of adding its files to Polly.

This also does not yet include the switch to small-integer optimized ISL
nor enabling C99 mode required for the former. Those will come as well
in separate patches.

Tobias Grosser 52a25237d8 Import isl(+imath) as an external library into Polly
With this patch Polly is always GPL-free (no dependency on GMP any more). As a
result, building and distributing Polly will be easier. Furthermore, there is no
need to tightly coordinate isl and Polly releases anymore.

We import isl b3e0fa7a05d as well as imath 4d707e5ef2. These are the git
versions Polly currently was tested with when using utils/checkout_isl.sh. The
imported libraries are both MIT-style licensed.

We build isl and imath with -fvisibility=hidden to avoid clashes in case other
projects (such as gcc) use conflicting versions of isl. The use of imath can
temporarily reduce compile-time performance of Polly. We will work on
performance tuning in tree.

Patches to isl should be contributed first to the main isl repository and can
then later be reimported to Polly.

This patch is also a prerequisite for the upcoming isl C++ interface.
