Summary

All of the removed code is handled by the FAST_DEPEND code.

A suspicious looking removals are in bsd.prog.mk/bsd.lib.mk but they were
replaced by a OBJS_DEPEND_GUESS variable that bsd.dep.mk now handles
when there is no .depend.<foo.o> file.

I am unsure if I missed more in sys/conf that can come out.

Fix a comment and remove more from sys/conf.

This is now redundant.

Ah right, I intended to remove all of the 'make depend' in here too. Thanks.

Remove leftover tree-walks and NO_KERNELDEPEND references. Also fixup build.7 documentation for new depend.

This will break some of my finger memory :-)

hselasky edited edge metadata.

Looks OK with regard to the kern.post.mk mlx5 related changes.

Keep old stage numbers

Although I do have searched build logs with /4\.4/, the comment was mostly in jest. Having a missing 4.3 is probably more confusing.

Don't skip stage numbers

emaste edited edge metadata.

I think this is fine. This stuff is subtle and I'm a bit worried about edge cases, but I don't see a good way to find them other than committing.

A word is missing (probably "on"), but "depending" is likely not the best choice of word here, either. The wording is so vague it is hard to suggest something clearer. Something about how TARGET affects which config files are used, at a guess.

share/man/man7/build.7
128

Quotes are not needed here. They are only necessary when single parameter will be mistaken to be multiples because of whitespace. No harm, though.

sys/conf/kern.post.mk
151

spelling error

Makefile.inc1

Indeed, but this predates @bdrewery's changes by a decade and a half or so. This should be improved in a separate commit.

sys/conf/kern.post.mk
151

As above, perhaps in a separate commit

brooks edited edge metadata.

No obvious issues in the diff. I've been running our local tree with FAST_DEPEND as the default for quite a while now and haven't had any issues.
