[X86] Extend pfm counter coverage for llvm-exegesis
Extension to rL348617, turns out llvm-exegesis doesn't need to match the perf counter name against a scheduler model resource name - so I've added a few more counters that I could find in the libpfm4 source code (and fix a typo in the knl/knm retired_uops counter - which uses 'all' instead of 'any'). llvm-svn: 348721 |

[X86] Improve pfm counter coverage for llvm-exegesis
This patch attempts to improve pfm perf counter coverage for all the x86 CPUs that libpfm4 supports. Intel/AMD CPU families tend to share names for cycle/uops counters so even if they don't have a scheduler model yet they can at least use the default values (checked against the libpfm4 source code). The remaining CPUs (where their port/pipe resource counters are known) I've tried to add to the existing model mappings. These are untested but don't represent a regression to current llvm-exegesis behaviour for these CPUs. Differential Revision: https://reviews.llvm.org/D55432 llvm-svn: 348617 |

[llvm-exegesis][NFC] Add a way to declare the default counter binding for unbound CPUs for a target.
Summary: This simplifies the code and moves everything to tablegen for consistency. This also prepares the ground for adding issue counters.

AMD BdVer2 (Piledriver) Initial Scheduler model
Summary:
# Overview
This is somewhat partial.
* Latencies are good {F7371125}
* All of these remaining inconsistencies //appear// to be noise/noisy/flaky.
* NumMicroOps are somewhat good {F7371158}
* Most of the remaining inconsistencies are from `Ld` / `Ld_ReadAfterLd` classes
* Actual unit occupation (pipes, `ResourceCycles`) are undiscovered lands, i did not really look there.
They are basically verbatum copy from `btver2`
* Many `InstRW`. And there are still inconsistencies left...
To be noted:
I think this is the first new schedule profile produced with the new next-gen tools like llvm-exegesis!
# Benchmark
I realize that isn't what was suggested, but i'll start with some "internal" public real-world benchmark i understand - [[ https://github.com/darktable-org/rawspeed | RawSpeed raw image decoding library ]].

{F7443905}
If we look at the `_mean`s, the time column, the biggest win is `-7.7%` (`Canon/EOS 5D Mark II/10.canon.sraw2.cr2`),
and the biggest loose is `+3.3%` (`Panasonic/DC-GH5S/P1022085.RW2`);
Overall: mean `-0.7436%`, median `-0.23%`, `cbrt(sum(time^3))` = `-8.73%`
Looks good so far i'd say.

[X86][BtVer2] Added Jaguar FPU Pipe0/1 uop counters to permit basic llvm-exegesis uop testing
We don't have PMCs to cover many of the Jaguar resources but we can at least monitor the FPU issue pipes which give an indication of the fpu uop count, just not the execution resources. llvm-svn: 336089 |

[X86][BtVer2] Added Jaguar cpu cycle counter to permit llvm-exegesis latency testing
Ideally we'd be able to test a CPU by using __builtin_readcyclecounter()/RDTSC instead (PR37193) if a model/cycle-counter is not specified. NOTE: Jaguar PMCs don't give good coverage of resource pipes specified in the model (at the macro-vs-micro-op levels) but we should be able to cover at least a few resources. llvm-svn: 333190 |

[MC][TableGen] Add optional libpfm counter names for ProcResUnits.
Summary: Subtargets can define the libpfm counter names that can be used to measure cycles and uops issued on ProcResUnits. This allows making llvm-exegesis available on more targets. Fixes PR36984.
