| * | [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 | ||||
| * | [Simplify] Remove writes that are overwritten. | Michael Kruse | 2017-05-13 | 1 | -0/+47 |
| Remove memory writes that are overwritten by later writes. This works for StoreInsts: store double 21.0, double* %A store double 42.0, double* %A scalar writes at the end of a statement and mixes of these. Multiple writes can be the result of DeLICM, which might map multiple writes to the same location when it knows that these do no conflict (for instance because they write the same value). Such writes interfere with pattern-matched optimization such as gemm and may not get removed by other LLVM passes after code generation.
