Tobias Grosser 2c543e775f Update isl to isl-0.19-185-g8e9f55ce
This is mainly a maintenance update.

Tobias Grosser fa8079d0dc 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.

Tobias Grosser 59d23bbdc6 Update isl to isl-0.18-282-g12465a5
Besides a variety of smaller cleanups, this update also contains a correctness
fix to isl coalesce which resolves a crash in Polly.

Tobias Grosser 72745c2ef5 Updated isl to isl-0.18-254-g6bc184d
This update includes a couple more coalescing changes as well as a large
number of isl-internal code cleanups (dead assigments, ...).

Michael Kruse 1b8eb4104b Update to isl-0.17.1-314-g3106e8d
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.

Tobias Grosser 06e1592663 Update to isl-0.17.1-267-gbf9723d
This update corrects an incorrect generation of min/max expressions in the isl
AST generator and a problematic nullptr dereference.

Tobias Grosser 9321e208e8 Update isl to isl-0.17.1-243-g24c0339
This introduces big-endian support in imath and resolves

Tobias Grosser b2f399264d Update isl to 93b8e43d
This update brings mostly interface cleanups, but also fixes two bugs in
imath (a memory leak, some undefined behavior).

Tobias Grosser e395da7986 Update isl to 0980603 'isl_tab_pip.c: parallel_constraints: drop useless 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.

Tobias Grosser 52a25237d8 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.
