rS360443: config: Add no-ctfconvert support.
Summary

Some files may purposely have debug info disabled or are *source files*
that attempt to run ctfconvert on them. Currently ctfconvert ignores
these errors but I have a change to make the errors real so we can
catch real problems like exceeding type limits.

I am not sure what to do with the versions/bootstrap here.

It looks right to me. I'm not sure how to handle bootstrapping either.

Change these to hex while here?

I think Kyle has looked at config(8) somewhat recently, maybe he has some insight here.

Could just set NO_OBJ | NO_CTFCONVERT here.

815

And then this test would just be for NO_CTFCONVERT, which seems reasonable given what the branch does. Not a big deal.

This should entail a CONFIGVERS bump to 600018 with a %VERSREQ bump to that version in all affected sys/conf/Makefile.* when a change is made that requires the new no-ctfconvert syntax. Tagging in @imp , though.

@cem NO_OBJ has more behavior than NO_CTFCONVERT down in do_objs.

Will need to remember to bump config version for anything that uses a driver that's tagged with this.

I don't think that's responsive to my suggestion, or at least I'm not seeing it.

The idea would be: "no-obj" sets both the NO_OBJ and NO_CTFCONVERT flags.

Then when we decide whether or not to emit "NORMAL_CTFCONVERT", we choose only on the basis of the NO_CTFCONVERT flag.

The only way this would break existing NO_OBJ logic is if something does an equality test for NO_OBJ rather than a flag bit test. If something does, I think it's already broken (given other attributes may be set already).

I misinterpreted your suggestion as setting NO_OBJ with no-ctfconvert. I get it now.
