Add IIC_ prefix to PPC instruction-class names This adds the IIC_ prefix to the instruction itinerary class names, giving the PPC backend a naming convention for itinerary classes that is more consistent with that used by the X86 and ARM backends. Instruction scheduling in the PPC backend needs a bunch of cleanup and improvement (especially for the ooo cores). This is just a preliminary step.

[PowerPC] Better scheduling for isel on P7/P8 isel is actually a cracked instruction on the P7/P8, and must start a dispatch group. The scheduling model should reflect this so that we don't bunch too many of them together when possible.

Add a scheduling model (with itinerary) for the PPC POWER7 This adds a scheduling model for the POWER7 (P7) core, and enables the machine-instruction scheduler when targeting the P7. Scheduling for the P7, like earlier ooo PPC cores, requires considering both dispatch group hazards, and functional unit resources and latencies. These are both modeled in a combined itinerary. Dispatch group formation is still handled by the post-RA scheduler (which still needs to be updated for the P7, but nevertheless does a pretty good job). One interesting aspect of this change is that I've also enabled to use of AA duing CodeGen for the P7 (just as it is for the embedded cores). The benchmark results seem to support this decision (see below), and while this is normally useful for in-order cores, and not for ooo cores like the P7, I think that the dispatch slot hazards are enough like in-order resources to make the AA useful. Test suite significant performance differences (where negative is a speedup, and positive is a regression) vs. the current situation: MultiSource/Benchmarks/BitBench/drop3/drop3 with AA: N/A without AA: -28.7614% +/- 19.8356% (significantly against AA) MultiSource/Benchmarks/FreeBench/neural/neural with AA: -17.7406% +/- 11.2712% without AA: N/A (significantly in favor of AA) MultiSource/Benchmarks/SciMark2-C/scimark2 with AA: -11.2079% +/- 1.80543% without AA: -11.3263% +/- 2.79651% MultiSource/Benchmarks/TSVC/Symbolics-flt/Symbolics-flt with AA: -41.8649% +/- 17.0053% without AA: -34.5256% +/- 23.7072% MultiSource/Benchmarks/mafft/pairlocalalign with AA: 25.3016% +/- 17.8614% without AA: 38.6629% +/- 14.9391% (significantly in favor of AA) MultiSource/Benchmarks/sim/sim with AA: N/A without AA: 13.4844% +/- 7.18195% (significantly in favor of AA) SingleSource/Benchmarks/BenchmarkGame/Large/fasta with AA: 15.0664% +/- 6.70216% without AA: 12.7747% +/- 8.43043% SingleSource/Benchmarks/BenchmarkGame/puzzle with AA: 82.2713% +/- 26.3567% without AA: 75.7525% +/- 41.1842% SingleSource/Benchmarks/Misc/flops-2 with AA: -37.1621% +/- 20.7964% without AA: -35.2342% +/- 20.2999% (significantly in favor of AA) These are 99.5% confidence intervals from 5 runs per configuration. Regarding the choice to turn on AA during CodeGen, of these results, four seem significantly in favor of using AA, and one seems significantly against. I'm not making this decision based on these numbers alone, but these results seem consistent with results I have from other tests, and so I think that, on balance, using AA is a win. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195981 91177308-0d34-0410-b5e6-96231b3b80d8
