Dear GCC Developers! May I ask you regarding how you make a decision whether implement some optimization or not? As far as I know, there are so many configurations (frontends x backends x applications(benchmarks) x etc), that the same optimization could improve performance in one configuration and degrade at other conditions. What performance tests do you perform before including an optimization in GCC? How do you aggregate the results (taking into account different behavior on different frontend/backend/benchmarks)? Excuse me, if some information is available in GCC documentation, didn’t found so far.
Thank you! Evgeniya
