History

Tobias Grosser 26d1050da3 Update isl to include isl_val changes The latest version of isl includes a new data type isl_val, which properly hides the multi precision math library used by isl. In Polly we would like to replace all uses of isl_int with the corresponding isl_val interfaces. This will allow us to switch the multi precision math library in isl. This is especially interesting for people who would like to replace libgmp with a non-gpl licensed library (e.g. imath). llvm-svn: 183026		2013-05-31 18:04:56 +00:00

Polly - Polyhedral optimizations for LLVM
-----------------------------------------
http://polly.llvm.org/

Polly uses a mathematical representation, the polyhedral model, to represent and
transform loops and other control flow structures. Using an abstract
representation it is possible to reason about transformations in a more general
way and to use highly optimized linear programming libraries to figure out the
optimal loop structure. These transformations can be used to do constant
propagation through arrays, remove dead loop iterations, optimize loops for
cache locality, optimize arrays, apply advanced automatic parallelization, drive
vectorization, or they can be used to do software pipelining.
