I don’t know what it’s doing, only how long it takes. My test was to build and then build again. In many cases I am only changing a source file far downstream in dependencies but I am rebuilding everything because I just push the build button in Xcode or type make. > That llint step really does depend on most headers in WTF and JSC, so if you > change any of them then I would expect a rebuild of that file.

In many other cases skipping the entire build step based on file modification times is a great approach. I understand it might be hard to know which files need to be checked in a case like this so maybe that’s why we can’t apply the classic solution. — Darin _______________________________________________ webkit-dev mailing list firstname.lastname@example.org https://lists.webkit.org/mailman/listinfo/webkit-dev
