fix rebuilding individual *Binding
Try the following sequence of steps: 1) Build dom/bindings/. 2) Modify a webidl file of your choice to include an attribute. 3) Copy the corresponding .cpp out of the way. 4) Run make -C dom/bindings/ name_of_file.cpp. 5) Diff the file from step 3 and the file from step 5. 6) Observe no difference.
This only seems to be a problem for rebuilding individual files. I suppose there could be other lurking issues, though...?

Does that not force all .cpp files to be regenerated during a build if _any_ webidl file changed?
(In reply to Boris Zbarsky (:bz) from comment #2) > Does that not force all .cpp files to be regenerated during a build if _any_ > webidl file changed? ParserResults.pkl already depends on all the webidl files right now. So right now, make should detect that, rebuild ParserResults.pkl and the global headers, then rebuild the .cpp files. This patch is just making explicit some dependencies that were more roundabout before. Another alternative would be to make the deps files for the individual .cpp/.h files more accurate by including the global headers. I think that should have the same effect.
I thought make was rebuilding the .cpp files based on the relevant deps files, so in fact right now a change to webidl will change ParserResults.pkl but NOT rebuild all the .cpp files.
You are correct. But building individual .cpp files does not work correctly. Building individual .o files does seem to work correctly.
