* Update isl to isl-0.18-9-gd4734f3Tobias Grosser2016-12-221-1/+0

* Update to isl-0.17.1-314-g3106e8dMichael Kruse2016-12-061-0/+1
| | | | | | | | | | | | 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 Grosser2016-11-041-1/+0
| | | | | | | This introduces big-endian support in imath and resolves http://llvm.org/PR24632. llvm-svn: 285993
* Update ISL to isl-0.17.1-200-gd8de4ea.Michael Kruse2016-08-171-1065/+1456
| | | | | | This version fixes a bug in set coalescing. llvm-svn: 278936
* Update isl to isl-0.17.1-57-g1879898Tobias Grosser2016-06-121-1456/+1065
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 to ISL 0.17.Michael Kruse2016-05-041-1065/+1456
| | | | | | | | | | | | 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
* Replace repository version of ISL by 'make dist' outputMichael Kruse2015-06-221-0/+7997
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
