Christian Sigg	0bf4a82a5a	[mlir] Use mlir::OpState::operator->() to get to methods of mlir::Operation. This is a preparation step to remove the corresponding methods from OpState. ... Reviewed By: silvas, rriddle Differential Revision: https://reviews.llvm.org/D92878	2020-12-09 12:11:32 +01:00
Christian Sigg	c4a0405902	Add `Operation* OpState::operator->()` to provide more convenient access to members of Operation. ... Given that OpState already implicit converts to Operator*, this seems reasonable. The alternative would be to add more functions to OpState which forward to Operation.

Alex Zinenko	119545f433	[mlir] Add conversion from SCF parallel loops to OpenMP ... Introduce a conversion pass from SCF parallel loops to OpenMP dialect constructs - parallel region and workshare loop. Loops with reductions are not supported because the OpenMP dialect cannot model them yet. The conversion currently targets only one level of parallelism, i.e. only one top-level `omp.parallel` operation is produced even if there are nested `scf.parallel` operations that could be mapped to `omp.wsloop`. Nested parallelism support is left for future work. Reviewed By: kiranchandramohan Differential Revision: https://reviews.llvm.org/D91982	2020-11-24 21:12:56 +01:00
