* [llvm-exegesis] Add uop computation for more X87 instruction classes.Clement Courbet2018-07-051-60/+67
| | | | | | | | | | | | | | Summary: This allows measuring comparisons (UCOM_FpIr32,UCOM_Fpr32,...), conditional moves (CMOVBE_Fp32,...) Reviewers: gchatelet Subscribers: tschuett, llvm-commits Differential Revision: https://reviews.llvm.org/D48713 llvm-svn: 336352

| | | | | | | | | | | | | | subtarget features. Summary: This fixes PR38008. Reviewers: gchatelet, RKSimon Subscribers: tschuett, craig.topper, llvm-commits Differential Revision: https://reviews.llvm.org/D48820 llvm-svn: 336171
* [llvm-exegesis][NFC] Cleanup useless braces.Clement Courbet2018-07-021-16/+8

* [llvm-exegesis] Add partial X87 support.Clement Courbet2018-06-281-33/+100
| | | | | | | | | | | | | | Summary: This enables the X86-specific X86FloatingPointStackifierPass, and allow llvm-exegesis to generate and measure X87 latency/uops for some FP ops. Reviewers: gchatelet Subscribers: tschuett, llvm-commits Differential Revision: https://reviews.llvm.org/D48592 llvm-svn: 335815
* [llvm-exegesis][NFC] Fix windows warning in rL335465.Clement Courbet2018-06-261-1/+1
| | | | llvm-svn: 335591
* [llvm-exegesis] Get the BenchmarkRunner from the ExegesisTarget.Clement Courbet2018-06-261-0/+50
| | | | | | | | | | | | | | | 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. Reviewers: gchatelet Subscribers: mgorny, tschuett, llvm-commits Differential Revision: https://reviews.llvm.org/D48587 llvm-svn: 335582
* [llvm-exegesis] Generate snippet setup code.Clement Courbet2018-06-251-0/+82
| | | | | | | | | | | | | | | Summary: This ensures that the snippet always sees the same values for registers, making measurements reproducible. This will also allow exploring different values.

* [llvm-exegesis] Add mechanism to add target-specific passes.Clement Courbet2018-06-201-1/+9
| | | | | | | | | | | | | | Summary: createX86FloatingPointStackifierPass is disabled until we handle TracksLiveness correctly. Reviewers: gchatelet Subscribers: mgorny, tschuett, llvm-commits Differential Revision: https://reviews.llvm.org/D48360 llvm-svn: 335117
