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
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:

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

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
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.

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
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
Besides a couple of cleanups and refactorings in isl, this change set fixes a
couple of bugs in isl, that can cause issues during code generation.
llvm-svn: 243110
This updated contains various changes to isl, including improvements to the
AST generator. For Polly, the most important change is a fix that unbreaks
builds on darwin (reported by: Jack Howard)
llvm-svn: 241048
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.
