This is version 3 of my series to resurrect automatic dependencies for GCC. Version 2 is here:
http://gcc.gnu.org/ml/gcc-patches/2013-07/msg01386.html Ordinarily I would simply ping the existing patches, but Alexandre asked me to resend the series and CC him. I've rebased the series and consequently made minor changes. Nothing important has changed -- I added pass-instances.def to generated_files (in patch #2) and of course the list of deleted things in patches #14 and #18 changes with each rebase. Tom
