* 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
* MachineFunction: Return reference from getFunction(); NFCMatthias Braun2017-12-151-1/+1

* [ARM] Use a Changed flag to avoid making a pass's return value dependent on ↵Craig Topper2017-05-081-1/+3
| | | | | | | | | | a compare with a Statistic object. Statistic compile to always be 0 in release build so this compare would always return false. And in the debug builds Statistic are global variables and remember their values across pass runs. So this compare returns true anytime the pass runs after the first time it modifies something. This was found after reviewing all usages of comparison operators on a Statistic object. We had some internal code that did a compare with a statistic that caused a mismatch in output between debug and release builds. So we did an audit out of paranoia. llvm-svn: 302450

* MachineFunctionProperties/MIRParser: Rename AllVRegsAllocated->NoVRegs, ↵Matthias Braun2016-08-251-1/+1
| | | | | | | | | | | | | compute it Rename AllVRegsAllocated to NoVRegs. This avoids the connotation of running after register and simply describes that no vregs are used in a machine function. With that we can simply compute the property and do not need to dump/parse it in .mir files. Differential Revision: http://reviews.llvm.org/D23850 llvm-svn: 279698

* Add MachineFunctionProperty checks for AllVRegsAllocated for target passesDerek Schuff2016-04-041-0/+5
| | | | | | | | | | | | | | Summary: This adds the same checks that were added in r264593 to all target-specific passes that run after register allocation. Reviewers: qcolombet Subscribers: jyknight, dsanders, llvm-commits Differential Revision: http://reviews.llvm.org/D18525 llvm-svn: 265313
* Revert r240137 (Fixed/added namespace ending comments using clang-tidy. NFC)Alexander Kornienko2015-06-231-1/+1
