History

Tobias Grosser c1a269bf0e Add option to assume single-loop scops with sufficient compute are profitable If a loop has a sufficiently large amount of compute instruction in its loop body, it is unlikely that our rewrite of the loop iterators introduces large performance changes. As Polly can also apply beneficical optimizations (such as parallelization) to such loop nests, we mark them as profitable. This option is currently "disabled" by default, but can be used to run experiments. If enabled by setting it e.g. to 40 instructions, we currently see some compile-time increases on LNT without any significant run-time changes. llvm-svn: 256199		2015-12-21 21:00:43 +00:00
