Simplify code for pinaware SEE This is the most compact and neatest version is was able to produce. On normal builds I have a small slowdown: normal builds base vs. simplification (gcc 4.8.1 Win7-64 i7-3770 @ 3.4GHz x86-64-modern) Results for 20 tests for each version: Base Test Diff Mean 1974744 1969333 5411 StDev 11825 10281 5874 p-value: 0,178 speedup: -0,003 On pgo-builds however I measure a nice 1.1% speedup pgo-builds base vs. simplification Results for 20 tests for each version: Base Test Diff Mean 1974119 1995444 -21325 StDev 8703 5717 4623 p-value: 1 speedup: 0,011 No functional change.
