* Update isl to isl-0.19-224-gce84a511Tobias Grosser2018-07-061-7/+52
| | | | | | | | This is a maintenance update. Besides many minor changes it ships two functions "isl_*_list_size" and "isl_*_list_get_at" which will allow us to simplify the iterator implementation in Polly. llvm-svn: 336425
* Update isl to isl-0.19-185-g8e9f55ceTobias Grosser2018-06-111-2/+70
| | | | | | This is mainly a maintenance update. llvm-svn: 334406
* Update isl to isl-0.19-173-g77fe2538Tobias Grosser2018-05-311-5/+30
| | | | | | | | | Besides other changes, this update introduces functions to translate a maps and sets into lists of their elements. These lists are useful as we can define iterators for lists, which allow us to replace many uses of foreach. llvm-svn: 333621
* Update isl to isl-0.19-152-g437e6ab0Tobias Grosser2018-05-231-0/+4
| | | | | | | | Besides normal updates this change also contains a bug-fix to in isl_coalesce which broke the AOSP buildbot. Thanks to Michael Kruse for reporting this bug and Sven Verdoolage for fixing this bug. llvm-svn: 333118

* Update isl to isl-0.19-107-gc4fe33d8Tobias Grosser2018-04-212-15/+51
| | | | | | This is a regular maintenance update. llvm-svn: 330496
* Update isl to isl-0.18-1047-g4a20ef8Tobias Grosser2018-02-202-36/+227
| | | | | | | | | | | | | | | | | | 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-0.18-812-g565da6eTobias Grosser2017-08-061-0/+6
| | | | | | | This update is mostly a maintenance update, but also exposes a couple of new functions that will be needed for the next version of the isl++ bindings. llvm-svn: 310205
* Update to isl-0.18-809-gd5b4535Tobias Grosser2017-08-011-0/+5
| | | | | | This fixes some undefined behavior in the isl schedule tree code. llvm-svn: 309727

| | | | | | | 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
* Updated isl to isl-0.18-254-g6bc184dTobias Grosser2017-02-172-0/+33
| | | | | | | This update includes a couple more coalescing changes as well as a large number of isl-internal code cleanups (dead assigments, ...). llvm-svn: 295419
* Do not track the isl PDF manual in SVNTobias Grosser2017-01-161-0/+0
| | | | | | | | There is no point in regularly committing a binary file to the repository, as this just unnecessarily increases the repository size. Interested people can find the isl manual for example at isl.gforge.inria.fr/manual.pdf. llvm-svn: 292105
* Update to isl-0.18-43-g0b4256fTobias Grosser2016-12-311-0/+0
| | | | | | Even more isl coalesce changes. llvm-svn: 290783

* Update to isl-0.17.1-314-g3106e8dMichael Kruse2016-12-061-0/+0
| | | | | | | | | | | | 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 to isl-0.17.1-284-gbb38638Tobias Grosser2016-11-221-0/+0
| | | | | | Regular maintenance update with only minor changes. llvm-svn: 287703
* Update to isl-0.17.1-267-gbf9723dTobias Grosser2016-11-162-10/+6
| | | | | | | This update corrects an incorrect generation of min/max expressions in the isl AST generator and a problematic nullptr dereference. llvm-svn: 287098
* Update isl to isl-0.17.1-243-g24c0339Tobias Grosser2016-11-041-0/+0
| | | | | | | This introduces big-endian support in imath and resolves http://llvm.org/PR24632. llvm-svn: 285993
* Update isl to isl-0.17.1-236-ga9c6cc7Tobias Grosser2016-10-202-2/+8
| | | | | | This includes isl_id_to_str, which is used in Michael's upcoming DeLICM patch. llvm-svn: 284689

| | | | | | This version has isl_space_has_equal_tuples added to the public API. llvm-svn: 280341
* Update ISL to isl-0.17.1-200-gd8de4ea.Michael Kruse2016-08-173-1/+4
| | | | | | This version fixes a bug in set coalescing. llvm-svn: 278936
* Update isl to isl-0.17.1-191-g540b2fdTobias Grosser2016-07-201-0/+0
| | | | | | This update resolves a bug in computing lexicographic minima/maxima. llvm-svn: 276138
* Update isl to isl-0.17.1-171-g233f589Tobias Grosser2016-07-201-0/+0
| | | | | | | This fixes an issue with equality detection that resulted in an assertion being triggered during coalescing. llvm-svn: 276094
* isl: isl-0.17.1-164-gcbba1b6Tobias Grosser2016-07-063-3/+54
| | | | | | | | | | | This is a regular maintenance update to ensure the latest version of isl is tested. Interesting Changes: - AST nodes and expressions are now printed as YAML llvm-svn: 274614
* Update isl to isl-0.17.1-84-g72ffe88Tobias Grosser2016-06-234-2/+20
| | | | | | | This is a regular maintenance update to ensure we are testing with a recent version of isl. llvm-svn: 273597
* Update isl to isl-0.17.1-57-g1879898Tobias Grosser2016-06-123-2/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | With this update the isl AST generation extracts disjunctive constraints early on. As a result, code that previously resulted in two branches with (close-to) identical code within them: if (P <= -1) { for (int c0 = 0; c0 < N; c0 += 1) Stmt_store(c0); } else if (P >= 1) for (int c0 = 0; c0 < N; c0 += 1) Stmt_store(c0); results now in only a single branch body: if (P <= -1 || P >= 1) for (int c0 = 0; c0 < N; c0 += 1) Stmt_store(c0); This resolves http://llvm.org/PR27559 Besides the above change, this isl update brings better simplification of sets/maps containing existentially quantified dimensions and fixes a bug in isl's coalescing. llvm-svn: 272500
* Update isl to isl-0.17-5-g57dc5ffTobias Grosser2016-05-071-0/+0
| | | | | | This update fixes an assertion in the isl scheduler. llvm-svn: 268853
* Update to ISL 0.17.Michael Kruse2016-05-0410-2122/+397
| | | | | | | | | | | | This release includes sevaral improvments compared to the previous version isl-0.16.1-145-g243bf7c (from the ISL 0.17 announcement): - optionally combine SCCs incrementally in scheduler - optionally maximize coincidence in scheduler - optionally avoid loop coalescing in scheduler - minor AST generator improvements - improve support for expansions in schedule trees llvm-svn: 268500
* Update to isl-0.16.1-145-g243bf7cTobias Grosser2016-03-252-3/+36
| | | | | | | Just an import to keep track with the latest version of isl. We are not looking for specific features. llvm-svn: 264452
* Update to isl-0.16.1-68-g8fad211Tobias Grosser2016-02-262-8/+87
| | | | | | | | This commit updates to the latest isl development version. There is no specific feature we need on the Polly side, but we want to ensure test coverage for the latest isl changes. llvm-svn: 262001
* Update to isl-0.16.1-20-gee54b48Tobias Grosser2016-02-042-8/+31
| | | | | | | | | | | | | | | | | | | | This includes some (optional) improvements to the isl scheduler, which we do not use yet, as well as a fix for a bug previously also affecting Polly: commit 662ee9b7d45ebeb7629b239d3ed43442e25bf87c Author: Sven Verdoolaege <skimo@kotnet.org> Date: Mon Jan 25 16:59:32 2016 +0100 isl_basic_map_realign: perform Gaussian elimination on result Many parts of isl assume that Gaussian elimination has been applied to the equality constraints. In particular singleton_extract_point makes this assumption. The input to singleton_extract_point may have undergone parameter alignment. This parameter alignment (ultimately performed by isl_basic_map_realign) therefore needs to make sure the result preserves this property llvm-svn: 259757
* Update to ISL 0.16.1Michael Kruse2016-01-152-7/+147

* Update isl to isl-0.15-142-gf101714Tobias Grosser2015-12-041-0/+0
| | | | | | | | | | This update brings in improvements to isl's 'isolate' option that reduce the number of code versions generated. This results in both code-size and compile time reduction for outer loop vectorization. Thanks to Roman Garev and Sven Verdoolaege for working on this improvement. llvm-svn: 254706
* Update isl to isl-0.15-140-g9279e30Michael Kruse2015-12-022-5/+17
| | | | | | | | | | The motivation is to fix a compilation error with Visual Studio 2013. See http://reviews.llvm.org/D14886. Thanks to Sumanth Gundapaneni for finding the issue and suggesting a patch. llvm-svn: 254498
* isl: Update to isl-0.15-136-g4d5654aTobias Grosser2015-11-212-2/+35
| | | | | | | | The most interesting change for Polly in this isl update is 4d5654af which in certain cases can speed up the construction of run-time checks from an isl set consisting of several disjuncts significantly. llvm-svn: 253794
* Update isl to isl-0.15-129-gb086c90Tobias Grosser2015-09-014-0/+36
| | | | llvm-svn: 246552
* Update isl to isl-0.15-117-ge42acfeTobias Grosser2015-08-112-0/+3
| | | | | | | | | | | 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
