I mean slow relative to Clang (despite Clang performs dataflow analysis in the FE): http://clang.llvm.org/features.html#performance http://clang.llvm.org/performance.html In any case, the main argument I got against adding dataflow to the FE was that it would slow it down. If this is not an issue anymore, it would be good to say so more publicly. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45468
