Not only are these abbreviated, but they are using different abbreviations even though their purposes are similar. Please use names made out of words instead of these abbreviations. > Source/WebCore/cssjit/SelectorCompiler.cpp:1299 > + default: > + ASSERT_NOT_REACHED(); Can we use return instead of break and remove this default case? 986193 3 benjamin 2014-03-02 16:00:07 -0800 Thanks for the review!

Then we could remove the default case and move the ASSERT_NOT_REACHED out of the switch and get a warning if someone adds a new case we don’t handle here. Unfortunately, match can be any selector type, not just the attribute types. > > Source/WebCore/cssjit/SelectorCompiler.cpp:1241 > > + bool valueStartsWithExpectedString; > > + if (caseSensitivity == CaseSensitive) > > + valueStartsWithExpectedString = valueImpl.startsWith(expectedString); > > + else > > + valueStartsWithExpectedString = valueImpl.startsWith(expectedString, false); > > + > > + if (!valueStartsWithExpectedString) > > + return false; > > Single line version of these 7 lines of code: > > if (!valueImpl.startsWith(expectedString, caseSensitivity == CaseSensitive)) Unfortunately, the version taking a boolean is quite a bit less efficient. 986220 4 benjamin 2014-03-02 17:42:51 -0800 Committed r164961: <http://trac.webkit.org/changeset/164961> 986240 5 ap 2014-03-02 19:16:10 -0800 This change caused assertion failures all over the place, and Ben is not around, rolling out: http://build.webkit.org/results/Apple%20Mavericks%20Debug%20WK2%20(Tests)/r164964%20(3038)/results.html 986242 6 commit-queue 2014-03-02 19:16:30 -0800 Re-opened since this is blocked by bug 129596 986255 7 benjamin 2014-03-02 19:58:16 -0800 (In reply to comment #5) > This change caused assertion failures all over the place, and Ben is not around, rolling out: > > http://build.webkit.org/results/Apple%20Mavericks%20Debug%20WK2%20(Tests)/r164964%20(3038)/results.html Damn, of course. Sorry about that, the assertion does not apply to one of the type. I have been unable to test in debug because JavaScriptCore was crashing all over the place for me.
