Jules Villard 78a33acb77 [cfg] run pre-analysis lazily in ondemand Summary: This also prints the CFGs after pre-analysis for individual procedures in infer-out/captured/<filename>/<proc>.dot. One can also look up the CFGs before pre-analysis in infer-out/captured/proc_cfgs_frontend.dot. Context: I want to add a pre-analysis that needs to look at proc attributes inter-procedurally. For this to make sense it has to happen after all of capture, and before analysis. Thus, this diff brings back the lazy running of the pre-analysis like in D15803492, except that we still make sure to run the pre-analyses systematically regardless of the checkers being run by running the pre-analysis from ondemand.ml. Also we don't need to re-introduce the "did_preanalysis" proc attribute for the same reason that the pre-analysis is now run once and for all by ondemand.ml (instead of each individual checker back in the days). This has the benefit of running the pre-analysis only when needed, and the drawback that several concurrent processes analysing the same proc descs will duplicate work. Since pre-analyses are supposed to be very fast I assume that neither is a big deal. If they become more expensive then the benefit gets bigger and the drawback is just the same as with regular analyses.
