* 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

* [SystemZ, MachineScheduler] Improve post-RA scheduling.Jonas Paulsson2017-08-171-8/+43
| | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to continue the scheduler state over an MBB boundary in the case where the successor block has only one predecessor. This means that the scheduler will continue in the successor block (after emitting any branch instructions) with e.g. maintained processor resource counters. Benchmarks have been confirmed to benefit from this. The algorithm in MachineScheduler.cpp that extracts scheduling regions of an MBB has been extended so that the strategy may optionally reverse the order of processing the regions themselves. This is controlled by a new method doMBBSchedRegionsTopDown(), which defaults to false. Handling the top-most region of an MBB first also means that a top-down scheduler can continue the scheduler state across any scheduling boundary between to regions inside MBB.

* [SystemZ] Post-RA scheduler implementationJonas Paulsson2016-10-201-0/+112
Post-RA sched strategy and scheduling instruction annotations for z196, zEC12 and z13. This scheduler optimizes decoder grouping and balances processor resources (including side steering the FPd unit instructions). The SystemZHazardRecognizer keeps track of the scheduling state, which can be dumped with -debug-only=misched. Reviers: Ulrich Weigand, Andrew Trick. https://reviews.llvm.org/D17260 llvm-svn: 284704
