The intention was to only allow the analyzer to resolve constants of arrays, structs and integral values. It seems to me that construction would have to be symbolically executed at the correct point in time and cannot be retroactively looked up - as is done with the constants here. > - Do we want to import non-const object's initializer expressions? The > analyzer might not end up using the value anyways. It seems like a good idea to not do that, since non-const values are not used. It might become useful if we ever do some kind of straight line execution from static initialization to main. However for structs it is enough if one of their fields is declared const. > - How big can the index get with this modification for large projects? That depends a lot on global usage of course. In LLVM for example there is little impact, but I don't have any numbers, it's taking too long. Taking care of the previous point helps here as well. > Overall the direction looks good to me, this will be a very useful addition, > thanks for working on this. I will prepare something to not store unnecessary entries in the index. I also noticed the AnalysisConsumer change has gone missing with my latest diff - will be fixed. https://reviews.llvm.org/D46421 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
