Well, remember that for now we don't #include *all* of your source files in one .cpp file, so this is actually not entirely true. We currently group the source files into batches of 16 and create one unified file per batch. > As it was pointed out in the "Analyze C++/compiler usage and code stats > easily" this could bring significant compilation time improvements too. That is the whole point of this project. :-) Cheers, -- Ehsan <http://ehsanakhgari.org/> _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
