* Bump isl to isl-0.18-768-g033b61aeTobias Grosser2017-07-041-133/+33
| | | | | | | | | | | | | | Summary: This is a general maintenance update Reviewers: grosser Subscribers: srhines, fedor.sergeev, pollydev, llvm-commits Contributed-by: Maximilian Falkenstein <falkensm@student.ethz.ch> Differential Revision: https://reviews.llvm.org/D34903 llvm-svn: 307090
* Update isl to isl-0.18-282-g12465a5Tobias Grosser2017-02-232-5/+5
| | | | | | | Besides a variety of smaller cleanups, this update also contains a correctness fix to isl coalesce which resolves a crash in Polly. llvm-svn: 295966
* Update to isl-0.17.1-314-g3106e8dMichael Kruse2016-12-061-0/+5
| | | | | | | | | | | | This version includes an update for imath (isl-0.17.1-49-g2f1c129). It fixes the compilation under windows, which does not know ssize_t. In addition, isl-0.17.1-288-g0500299 changed the way isl_test finds the source directory. It now generates a file isl_srcdir.c at configure-time, containing the source path, to not require setting the environment variable "srcdir" at test-time. The cmake build system had to be modified to also generate that file. llvm-svn: 288811
* Update isl to isl-0.17.1-243-g24c0339Tobias Grosser2016-11-041-76/+66
| | | | | | | This introduces big-endian support in imath and resolves http://llvm.org/PR24632. llvm-svn: 285993
* Replace repository version of ISL by 'make dist' outputMichael Kruse2015-06-2274-25508/+0
| | | | | | | | | | | The 'make dist' archive is not dependent on ./configure output and contains a GIT_HEAD_ID file that identifies the version of ISL used. None of the files added or removed are used part of Polly's build process (except of GIT_HEAD_ID since the previous revision r240301). No functional change intended. llvm-svn: 240306
* Update isl to 93b8e43dTobias Grosser2015-05-2813-1255/+14
| | | | | | | This update brings mostly interface cleanups, but also fixes two bugs in imath (a memory leak, some undefined behavior). llvm-svn: 238422
* Import isl(+imath) as an external library into PollyTobias Grosser2015-02-0480-0/+32410
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. llvm-svn: 228193
