Johannes Doerfert 6462d8c1d9 Generalize the domain complexity restrictions 
This patch applies the restrictions on the number of domain conjuncts
  also to the domain parts of piecewise affine expressions we generate.
  To this end the wording is change slightly. It was needed to support
  complex additions featuring zext-instructions but it also fixes PR27045.

  lnt profitable runs reports only little changes that might be noise:
  Compile Time:
    Polybench/[...]/2mm                     +4.34%
    SingleSource/[...]/stepanov_container   -2.43%
  Execution Time:
    External/[...]/186_crafty               -2.32%
    External/[...]/188_ammp                 -1.89%
    External/[...]/473_astar                -1.87%

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.
