* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [IAI,LV] Add support for vectorizing predicated strided accesses using maskedDorit Nuzman2018-10-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | interleave-group The vectorizer currently does not attempt to create interleave-groups that contain predicated loads/stores; predicated strided accesses can currently be vectorized only using masked gather/scatter or scalarization. This patch makes predicated loads/stores candidates for forming interleave-groups during the Loop-Vectorizer's analysis, and adds the proper support for masked-interleave- groups to the Loop-Vectorizer's planning and transformation stages. The patch also extends the TTI API to allow querying the cost of masked interleave groups (which each target can control); Targets that support masked vector loads/ stores may choose to enable this feature and allow vectorizing predicated strided loads/stores using masked wide loads/stores and shuffles.

* [VPlan] Move recipe construction to VPRecipeBuilder.Florian Hahn2018-06-081-0/+131
This patch moves the recipe-creation functions out of LoopVectorizationPlanner, which should do the high-level orchestration of the transformations. Reviewers: dcaballe, rengolin, hsaito, Ayal Reviewed By: dcaballe Differential Revision: https://reviews.llvm.org/D47595 llvm-svn: 334305
