* [llvm-exegesis] Fix r374158Clement Courbet2019-10-091-11/+11
| | | | | | | | | Some bots complain about missing 'class': LlvmState.h:70:40: error: declaration of ‘std::unique_ptr<const llvm::TargetMachine> llvm::exegesis::LLVMState::TargetMachine’ [-fpermissive] std::unique_ptr<const TargetMachine> TargetMachine; llvm-svn: 374162
* [llvm-exegesis][NFC] Remove extra `llvm::` qualifications.Clement Courbet2019-10-091-26/+22
| | | | | | | | | | | | | | Summary: Second patch: in the lib. Reviewers: gchatelet Subscribers: nemanjai, tschuett, MaskRay, mgrang, jsji, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D68692 llvm-svn: 374158
* [llvm-exegesis] Allow the target to disable the selection of some registers.Clement Courbet2019-03-261-2/+5
| | | | | | | | | | | | | | | | | | | | Summary: This prevents "Cannot encode high byte register in REX-prefixed instruction" from happening on instructions that require REX encoding when AH & co get selected. On the down side, these 4 registers can no longer be selected automatically, but this avoids having to expose all the X86 encoding complexity.

* 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-exegesis][NFC] More tests for ExegesisTarget::fillMemoryOperands().Clement Courbet2018-11-191-6/+7

* [MCSched] Bind PFM Counters to the CPUs instead of the SchedModel.Clement Courbet2018-10-251-2/+5
| | | | | | | | | | | | | | | | Summary: The pfm counters are now in the ExegesisTarget rather than the MCSchedModel (PR39165). This also compresses the pfm counter tables (PR37068).

* [llvm-exegesis] Move namespace exegesis inside llvm::Fangrui Song2018-10-221-0/+2
| | | | | | | | | | | | | | | | Summary: This allows simplifying references of llvm::foo with foo when the needs come in the future.

* [llvm-exegesis][NFC] Code simplificationGuillaume Chatelet2018-10-101-0/+2
| | | | | | | | | | | | Summary: Simplify code by having LLVMState hold the RegisterAliasingTrackerCache. Reviewers: courbet Subscribers: tschuett, llvm-commits Differential Revision: https://reviews.llvm.org/D53078 llvm-svn: 344143
* [llvm-exegesis] Get the BenchmarkRunner from the ExegesisTarget.Clement Courbet2018-06-261-0/+5
| | | | | | | | | | | | | | | Summary: This allows targets to override code generation for some instructions. As an example of override, this also moves ad-hoc instruction filtering for X86 into the X86 ExegesisTarget.

* [llvm-exegesis] Generate snippet setup code.Clement Courbet2018-06-251-0/+1
| | | | | | | | | | | | | | | Summary: This ensures that the snippet always sees the same values for registers, making measurements reproducible. This will also allow exploring different values.
