* Update isl to isl-0.18-1047-g4a20ef8Tobias Grosser2018-02-201-0/+2
| | | | | | | | | | | | | | | | | | This update: - Removes several deprecated functions (e.g., isl_band). - Improves the pretty-printing of sets by detecting modulos and "false" equalities. - Minor improvements to coalescing and increased robustness of the isl scheduler. This update does not yet include isl commit isl-0.18-90-gd00cb45 (isl_pw_*_alloc: add missing check for compatible spaces, Wed Sep 6 12:18:04 2017 +0200), as this additional check is too tight and unfortunately causes two test case failures in Polly. A patch has been submitted to isl and will be included in the next isl update for Polly. llvm-svn: 325557
* Update to isl-0.18-809-gd5b4535Tobias Grosser2017-08-011-12/+11
| | | | | | This fixes some undefined behavior in the isl schedule tree code. llvm-svn: 309727
* Update isl to isl-0.18-800-g4018f45Tobias Grosser2017-07-271-8/+76
| | | | | | | | | This fixes a bug in isl_flow where triggering the compute out could result in undefined or unexpected behavior. This fixes some recent regressions we saw in the android buildbots. Thanks Eli Friedman for reducing the corresponding test cases. llvm-svn: 309274
* Revert accidental isl changes in 308923Tobias Grosser2017-07-251-71/+6
| | | | | | | | | | | It seems I still had some incomplete changes in the tree when committing. In general, we only import changes from isl upstream. In this case, the changes were especially unfortunate, as they broke the error management in isl_flow.c and consequently caused regressions. Thanks to Michael Kruse for spotting this mistake. llvm-svn: 309039

* Update isl to isl-0.17.1-236-ga9c6cc7Tobias Grosser2016-10-201-0/+30
| | | | | | This includes isl_id_to_str, which is used in Michael's upcoming DeLICM patch. llvm-svn: 284689

* Update isl to isl-0.15-117-ge42acfeTobias Grosser2015-08-111-3/+7
| | | | | | | | | | | Besides other changes this version of isl contains a fundamental fix to memory corruption issues we have seen with imath-32 backed isl_ints. This update also contains a fix that ensures that the schedule-tree based version of isl's dependence analysis takes the domain of the schedule into account. llvm-svn: 244585
* Update ISL to isl-0.15-3-g532568aMichael Kruse2015-06-181-0/+30
| | | | | | | | | | | | | | This version adds small integer optimization, but is not active by default. It will be enabled in a later commit. The schedule-fuse=min/max option has been replaced by the serialize-sccs option. Adapting Polly was necessary, but retaining the name polly-opt-fusion=min/max.

* Update isl to 93b8e43dTobias Grosser2015-05-281-33/+36
| | | | | | | This update brings mostly interface cleanups, but also fixes two bugs in imath (a memory leak, some undefined behavior). llvm-svn: 238422
* Update isl to 6be6768eTobias Grosser2015-05-181-2/+4
| | | | | | | | Besides a couple of interface cleanups, this change also contains a performance optimization of isl_mat_product that should give us up to almost 6% compiletime reduction. llvm-svn: 237616
* Update isl to c3892bebc0Tobias Grosser2015-05-091-0/+5
| | | | | | Various smaller improvements and bugfixes. llvm-svn: 236932

| | | | | | | | | | | | | | assignment' This update contains: - Fixes of minor issues detected by clang's scan_build - More schedule tree infrastructure additions This update slightly changes the output of our dependence analysis, but these changes are purely syntactially. llvm-svn: 230528
* Import isl(+imath) as an external library into PollyTobias Grosser2015-02-041-0/+1496
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
