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). llvm-svn: 238422	2015-05-28 13:32:11 +00:00
Tobias Grosser	29e36dc0c6	Update isl to 285e92aea ... This is mostly a set of schedule tree enhancements which are not yet directly useful to Polly. llvm-svn: 233567	2015-03-30 17:28:57 +00:00
Tobias Grosser	1de4e381ca	Update isl to 94d707d ... The major improvements are: - Extended schedule tree support - AST generation from schedule trees llvm-svn: 232709	2015-03-19 07:27:29 +00:00
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. llvm-svn: 228193	2015-02-04 20:55:43 +00:00
