As aresult, building and distributing Polly will be easier. Furthermore, there is noneed to tightly coordinate isl and Polly releases anymore.We import isl b3e0fa7a05d as well as imath 4d707e5ef2. These are the gitversions Polly currently was tested with when using utils/checkout_isl.sh. Theimported libraries are both MIT-style licensed.We build isl and imath with -fvisibility=hidden to avoid clashes in case otherprojects (such as gcc) use conflicting versions of isl. The use of imath cantemporarily reduce compile-time performance of Polly. We will work onperformance tuning in tree.Patches to isl should be contributed first to the main isl repository and canthen later be reimported to Polly.This patch is also a prerequisite for the upcoming isl C++ interface.llvm-svn: 228193 List of files: /llvm-project-15.0.7/polly/lib/External/isl/test_inputs/codegen/omega/code_gen-0.c Wed, 04 Feb 2015 20:55:43 +0000 Tobias Grosser <tobias@grosser.es>
