* Apply llvm-prefer-register-over-unsigned from clang-tidy to LLVMDaniel Sanders2019-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This clang-tidy check is looking for unsigned integer variables whose initializer starts with an implicit cast from llvm::Register and changes the type of the variable to llvm::Register (dropping the llvm:: where possible). Partial reverts in: X86FrameLowering.cpp - Some functions return unsigned and arguably should be MCRegister X86FixupLEAs.cpp - Some functions return unsigned and arguably should be MCRegister X86FrameLowering.cpp - Some functions return unsigned and arguably should be MCRegister HexagonBitSimplify.cpp - Function takes BitTracker::RegisterRef which appears to be unsigned& MachineVerifier.cpp - Ambiguous operator==() given MCRegister and const Register PPCFastISel.cpp - No Register::operator-=() PeepholeOptimizer.cpp - TargetInstrInfo::optimizeLoadInstr() takes an unsigned& MachineTraceMetrics.cpp - MachineTraceMetrics lacks a suitable constructor Manual fixups in: ARMFastISel.cpp - ARMEmitLoad() now takes a Register& instead of unsigned& HexagonSplitDouble.cpp - Ternary operator was ambiguous between unsigned/Register HexagonConstExtenders.cpp - Has a local class named Register, used llvm::Register instead of Register. PPCFastISel.cpp - PPCEmitLoad() now takes a Register& instead of unsigned& Depends on D65919 Reviewers: arsenm, bogner, craig.topper, RKSimon Reviewed By: arsenm Subscribers: RKSimon, craig.topper, lenary, aemerson, wuzish, jholewinski, MatzeB, qcolombet, dschuff, jyknight, dylanmckay, sdardis, nemanjai, jvesely, wdng, nhaehnle, sbc100, jgravelle-google, kristof.beyls, hiraditya, aheejin, kbarton, fedor.sergeev, javed.absar, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, tpr, PkmX, jocewei, jsji, Petar.Avramovic, asbirlea, Jim, s.egerton, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D65962 llvm-svn: 369041
* CodeGen: Introduce a class for registersMatt Arsenault2019-06-241-2/+2
| | | | | | | | | Avoids using a plain unsigned for registers throughoug codegen. Doesn't attempt to change every register use, just something a little more than the set needed to build after changing the return type of MachineOperand::getReg(). llvm-svn: 364191
* Include what you use in LanaiRegisterInfo.cppDmitri Gribenko2019-06-031-2/+4

* 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
* Target/TargetInstrInfo.h -> CodeGen/TargetInstrInfo.h to match layeringDavid Blaikie2017-11-081-2/+2
| | | | | | | | This header includes CodeGen headers, and is not, itself, included by any Target headers, so move it into CodeGen to match the layering of its implementation. llvm-svn: 317647
* Move TargetFrameLowering.h to CodeGen where it's implementedDavid Blaikie2017-11-031-1/+1
| | | | | | | | | | | This header already includes a CodeGen header and is implemented in lib/CodeGen, so move the header there to match. This fixes a link error with modular codegeneration builds - where a header and its implementation are circularly dependent and so need to be in the same library, not split between two like this. llvm-svn: 317379
* [Lanai] Remove dead functions from LanaiRegisterInfoAlex Bradbury2017-08-231-10/+0
| | | | | | | | | getEHExceptionRegister and getEHHandlerRegister are unused and were removed from most backends in rL192099. This patch removes them from Lanai. Differential Revision: https://reviews.llvm.org/D36829 llvm-svn: 311531
* Lanai: Remove unnecessary canRealignStack() override; NFCMatthias Braun2017-04-261-6/+0
| | | | | | | | It was doing the same as the base implementation and was irritating me when I was searching for backends that have custom behavior for canRealignStack. llvm-svn: 301495
* MachineFunction: Return reference for getFrameInfo(); NFCMatthias Braun2016-07-281-4/+4
| | | | | | | getFrameInfo() never returns nullptr so we should use a reference instead of a pointer. llvm-svn: 277017

* [lanai] Use peephole optimizer to generate more conditional ALU operations.Jacques Pienaar2016-07-071-5/+10
| | | | | | | | | | | | | | | | | Summary: * Similiar to the ARM backend yse the peephole optimizer to generate more conditional ALU operations; * Add predicated type with default always true to RR instructions in LanaiInstrInfo.td; * Move LanaiSetflagAluCombiner into optimizeCompare; * The ASM parser can currently only handle explicitly specified CC, so specify ".t" (true) where needed in the ASM test; * Remove unused MachineOperand flags; Reviewers: eliben Subscribers: aemerson Differential Revision: http://reviews.llvm.org/D22072 llvm-svn: 274807
* [lanai] Change reloc to use PIC_ by default and cleanup.Jacques Pienaar2016-05-201-3/+2
| | | | | | | * Change reloc to PIC_; * Cleanup (clang-format & modify test); llvm-svn: 270282
* [lanai] Add Lanai backend.Jacques Pienaar2016-03-281-0/+282
Add the Lanai backend to lib/Target. General Lanai backend discussion on llvm-dev thread "[RFC] Lanai backend" (http://lists.llvm.org/pipermail/llvm-dev/2016-February/095118.html). Differential Revision: http://reviews.llvm.org/D17011 llvm-svn: 264578
