Update to isl 99d53692ba This commit imports the latest isl version into lib/External/isl. The changes relavant for Polly are: 1) Schedule trees [1] have been introduced as a more structured way to describe schedules. Polly does not yet use them, but we may switch to them in the near future. 2) Another set of coalescing changes [2] simplifies some data dependences and removes a couple of code generation artifacts. We now understand that the following sets can be merged: { Stmt_S1[i0, i1] -> Stmt_S2[i0 + i1] : i0 >= 0 and i1 <= 1023 - i0 and i1 >= 1 Stmt_S1[i0, 0] -> Stmt_S2[i0] : i0 <= 1023 and i0 >= 1} into: { Stmt_S1[i0, i1] -> Stmt_S2[i0 + i1] : i1 <= 1023 - i0 and i1 >= 0 and i1 >= 1 - i0 and i0 >= 0 } Changes of this kind reduce unnecessary specialization during code generation. - for (int c3 = 0; c3 <= 1023; c3 += 1) { - if (c3 % 2 == 0) { - Stmt_for_body3(c1, c3); - } else - Stmt_for_body3(c1, c3); - } + for (int c3 = 0; c3 <= 1023; c3 += 1) + Stmt_for_body3(c1, c3); [1] http://impact.gforge.inria.fr/impact2014/papers/impact2014-verdoolaege.pdf [2] http://impact.gforge.inria.fr/impact2015/papers/impact2015-verdoolaege.pdf llvm-svn: 229423

#define isl_union_set_list isl_union_map_list
Import isl(+imath) as an external library into Polly 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

Update isl to isl-0.18-1047-g4a20ef8 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
