I guess that could be useful when the JIT is disabled.

If that's not already covered, it would be good to add tests for:
-Failures on selectorForIdLookup()'s rootNode.inDocument() (Element.matches() on a detached element).
-Failures on selectorForIdLookup()'s rootNode.document().inQuirksMode().
-Tests for CompilableSingleWithRootFilter and CompilableSingle.
with cases that compiles with the CSS JIT, and cases that fail to compile.

Great! I'll add them.

Oops, thank you!

http://trac.webkit.org/changeset/181699 Landed with tests.
Accidentally webkit-patch crashed, I've closed this issue manually.

This broke the build with some compilers, because it doesn't make sense to FALLTHROUGH after an ASSERT.

Tim made a temporary fix in http://trac.webkit.org/changeset/181706, please fix this properly.

Thank you! I'll fix it soon.

OK, I've found that, when !ENABLE(CSS_SELECTOR_JIT) and --debug, both FALLTHROUGH and ASSERT_NOT_REACHED are materialized and raise this compile error.

Here, ASSERT_NOT_REACHED is correct because this CompiledSingle and CompiledSingleWithRootFilter is not set when !ENABLE(CSS_SELECTOR_JIT).
So I'll fix it by dropping this FALLTHROUGH in !ENABLE(CSS_SELECTOR_JIT) build.
