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. llvm-svn: 325557	2018-02-20 07:26:42 +00:00
Tobias Grosser	6e6264c142	[tests] Force invariant load hoisting for test cases that need it ... This will make it easier to switch the default of Polly's invariant load hoisting strategy and also makes it very clear that these test cases indeed require invariant code hoisting to work. llvm-svn: 278667	2016-08-15 13:27:49 +00:00
Johannes Doerfert	a60ad845c0	Simplify the internal representation according to the context [NFC] ... We now use context information to simplify the domains and access functions of the SCoP instead of just aligning them with the parameter space. llvm-svn: 269048	2016-05-10 12:18:22 +00:00
Johannes Doerfert	1dc12aff8a	Simplify the execution context for dereferencable loads ... If we know it is safe to execute a load we do not need an execution context, however only if we are sure it was modeled correctly. llvm-svn: 267284	2016-04-23 12:59:18 +00:00
