| * | [ScopBuilder] Make -polly-stmt-granularity=scalar-indep the default. | Michael Kruse | 2018-02-03 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | Splitting basic blocks into multiple statements if there are now additional scalar dependencies gives more freedom to the scheduler, but more statements also means higher compile-time complexity. Switch to finer statement granularity, the additional compile time should be limited by the number of operations quota. The regression tests are written for the -polly-stmt-granularity=bb setting, therefore we add that flag to those tests that break with the new default. Some of the tests only fail because the statements are named differently due to a basic block resulting in multiple statements, but which are removed during simplification of statements without side-effects. Previous commits tried to reduce this effect, but it is not completely avoidable. Differential Revision: https://reviews.llvm.org/D42151 llvm-svn: 324169 | ||||
| * | [ZoneAlgo/ForwardOpTree] Normalize PHIs to their known incoming values. | Michael Kruse | 2017-10-31 | 1 | -0/+154 |
| Represent PHIs by their incoming values instead of an opaque value of themselves. This allows ForwardOpTree to "look through" the PHIs and forward the incoming values since forwardings PHIs is currently not supported. This is particularly useful to cope with PHIs inserted by GVN LoadPRE. The incoming values all resolve to a load from a single array element which then can be forwarded. It should in theory also reduce spurious conflicts in value mapping (DeLICM), but I have not yet found a profitable case yet, so it is not included here. To avoid transitive closure and potentially necessary overapproximations of those, PHIs that may reference themselves are excluded from normalization and keep their opaque self-representation.
