* 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
* [VPlan] Introduce VPlan-based dominator analysis.Diego Caballero2018-07-301-3/+20
| | | | | | | | | | | | | | | The patch introduces dominator analysis for VPBlockBases and extend VPlan's GraphTraits specialization with the required interfaces. Dominator analysis will be necessary to perform some H-CFG transformations and to introduce VPLoopInfo (LoopInfo analysis on top of the VPlan representation).

* [LV][VPlan] Build plain CFG with simple VPInstructions for outer loops.Diego Caballero2018-05-171-0/+55
Patch #3 from VPlan Outer Loop Vectorization Patch Series #1 (RFC: http://lists.llvm.org/pipermail/llvm-dev/2017-December/119523.html). Expected to be NFC for the current inner loop vectorization path. It introduces the basic algorithm to build the VPlan plain CFG (single-level CFG, no hierarchical CFG (H-CFG), yet) in the VPlan-native vectorization path using VPInstructions. It includes: - VPlanHCFGBuilder: Main class to build the VPlan H-CFG (plain CFG without nested regions, for now). - VPlanVerifier: Main class with utilities to check the consistency of a H-CFG. - VPlanBlockUtils: Main class with utilities to manipulate VPBlockBases in VPlan.
