2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+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
2017-12-15MachineFunction: Return reference from getFunction(); NFCMatthias Braun1-1/+1
The Function can never be nullptr so we can return a reference. llvm-svn: 320884
2017-11-17Fix a bunch more layering of CodeGen headers that are in TargetDavid Blaikie1-1/+1
All these headers already depend on CodeGen headers so moving them into CodeGen fixes the layering (since CodeGen depends on Target, not the other way around). llvm-svn: 318490
2017-11-08Target/TargetInstrInfo.h -> CodeGen/TargetInstrInfo.h to match layeringDavid Blaikie1-2/+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
2017-11-03Move TargetFrameLowering.h to CodeGen where it's implementedDavid Blaikie1-1/+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
2017-08-01[X86] Fix a crash in FEntryInserter Pass.Manoj Gupta1-3/+1
Summary: FEntryInserter pass unconditionally derefs the first Instruction in the first Basic Block. The pass crashes when the first BasicBlock is empty. Fix the crash by not dereferencing the basic Block iterator. This fixes an issue observed when building Linux kernel 4.4 with clang. Fixes PR33971.
