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 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

[Polly] Update ISL to isl-0.22.1-87-gfee05a13. The primary motivation is to fix an assertion failure in isl_basic_map_alloc_equality: isl_assert(ctx, room_for_con(bmap, 1), return -1); Although the assertion does not occur anymore, I could not identify which of ISL's commits fixed it. Compared to the previous ISL version, Polly requires some changes for this update * Since ISL commit 20d3574 "perform parameter alignment by modifying both arguments to function" isl_*_gist_* and similar functions do not always align the paramter list anymore. This caused the parameter lists in JScop files to become out-of-sync. Since many regression tests use JScop files with a fixed parameter list and order, we explicitly call align_params to ensure a predictable parameter list. * ISL changed some return types to isl_size, a typedef of (signed) int. This caused some issues where the return type was unsigned int before: - No overload for std::max(unsigned,isl_size) - It cause additional 'mixed signed/unsigned comparison' warnings. Since they do not break compilation, and sizes larger than 2^31 were never supported, I am going to fix it separately. * With the change to isl_size, commit 57d547 "isl_*_list_size: return isl_size" also changed the return value in case of an error from 0 to -1. This caused undefined looping over isl_iterator since the 'end iterator' got index -1, never reached from the 'begin iterator' with index 0. * Some internal changes in ISL caused the number of operations to increase when determining access ranges to determine aliasing overlaps. In one test, this caused exceeding the default limit of 800000. The operations-limit was disabled for this test.
