Added arcanist linters and cleaned errors and warnings Arcanist (arc) will now always run linters before uploading any new commit to Phabricator. All errors/warnings (or their absence) will be shown in the web interface together with a explanation by the commiter (arcanist will ask the commiter if the build was not clean). The linters include: - clang-format - spelling check - permissions check (aka. chmod) - filename check - merge conflict marker check Note, that their scope is sometimes limited (see .arclint for details). This commit also fixes all errors and warnings these linters reported, namely: - spelling mistakes and typos - executable permissions for various text files Differential Revision: http://reviews.llvm.org/D4916 llvm-svn: 215871

Add preliminary implementation for GPGPU code generation. Translate the selected parallel loop body into a ptx string and run it with the cuda driver API. We limit this preliminary implementation to target the following special test cases: - Support only 2-dimensional parallel loops with or without only one innermost non-parallel loop. - Support write memory access to only one array in a SCoP. The patch was committed with smaller changes to the build system: There is now a flag to enable gpu code generation explictly. This was required as we need the llvm.codegen() patch applied on the llvm sources, to compile this feature correctly. Also, enabling gpu code generation does not require cuda. This requirement was removed to allow 'make polly-test' runs, even without an installed cuda runtime. Contributed by: Yabin Hu <yabin.hwu@gmail.com> llvm-svn: 161239

autoconf: Only define GPGPU_CODEGEN, if that feature is requested Before we defined GPGPU_CODEGEN to '0', which does not disable the relevant code as we just check if that value is defined at all. We now follow the cmake approach and only define GPGPU_CODEGEN, if the feature should be enabled. Reported by: Sebastian Pop <spop@codeaurora.org> llvm-svn: 162275

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.
