* [llvm] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere2019-08-151-4/+4
| | | | | | | | Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. llvm-svn: 369013
* [MemorySSA] Make insertDef insert corresponding phi nodes.Alina Sbirlea2019-02-271-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The original assumption for the insertDef method was that it would not materialize Defs out of no-where, hence it will not insert phis needed after inserting a Def. However, when cloning an instruction (use case used in LICM), we do materialize Defs "out of no-where". If the block receiving a Def has at least one other Def, then no processing is needed. If the block just received its first Def, we must check where Phi placement is needed. The only new usage of insertDef is in LICM, hence the trigger for the bug. But the original goal of the method also fails to apply for the move() method. If we move a Def from the entry point of a diamond to either the left or right blocks, then the merge block must add a phi. While this usecase does not currently occur, or may be viewed as an incorrect transformation, MSSA must behave corectly given the scenario. Resolves PR40749 and PR40754.

* [opaque pointer types] Pass value type to GetElementPtr creation.James Y Knight2019-02-011-1/+1
| | | | | | | | | This cleans up all GetElementPtr creation in LLVM to explicitly pass a value type rather than deriving it from the pointer's element-type. Differential Revision: https://reviews.llvm.org/D57173 llvm-svn: 352913
* [opaque pointer types] Pass value type to LoadInst creation.James Y Knight2019-02-011-27/+27
| | | | | | | | | This cleans up all LoadInst creation in LLVM to explicitly pass the value type rather than deriving it from the pointer's element-type. Differential Revision: https://reviews.llvm.org/D57172 llvm-svn: 352911
* 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
* llvm::sort(C.begin(), C.end(), ...) -> llvm::sort(C, ...)Fangrui Song2018-09-271-4/+3
| | | | | | | | | | | | Summary: The convenience wrapper in STLExtras is available since rL342102.

* API to update MemorySSA for cloned blocks and added CFG edges.Alina Sbirlea2018-09-101-0/+192
| | | | | | | | | | | | | | | | Summary: End goal is to update MemorySSA in all loop passes. LoopUnswitch clones all blocks in a loop. SimpleLoopUnswitch clones some blocks. LoopRotate clones some instructions. Some of these loop passes also make CFG changes. This is an API based on what I found needed in LoopUnswitch, SimpleLoopUnswitch, LoopRotate, LoopInstSimplify, LoopSimplifyCFG. Adding dependent patches using this API for context.

* Rename a few unittests/.../Foo.cpp files to FooTest.cppNico Weber2018-09-031-0/+1395
The convention for unit test sources is that they're called FooTest.cpp. No behavior change. https://reviews.llvm.org/D51579 llvm-svn: 341313
