make buildkernel not -j >1 safe?
0%
Description
It appears a `make buildkernel` is not safe for more than one parallel
make. The fast scrolling output didn't make things very clear, but I
highly suspect there is no proper .ORDER -ing of the mkdep phase. Where
it normally is busy for a couple of seconds doing that, it now rushes
right along. I'm not enough of a Makefile guru to fix that though, I fear.

I hope kern.fwd.mk rev 1.6 fixes your problem.
Cheers.

Alas, it doesn't. The exact error is:

Is this perhaps done before the fwd phase, or part of it?

It seems the BEFORE_DEPEND stuff is done too soon. Perhaps the .ORDER in
kern.fwd.mk should read something like this:
.ORDER: ${_MACHINE_FWD}/include/machine ${_FWDHDRS} assym.s ${_LHDRS}
Would that be possible?

.ORDER: ${_MACHINE_FWD}/include/machine ${_FWDHDRS} ${_LHDRS}
${BEFORE_DEPEND} \
genassym.o
Only fixes the BEFORE_DEPEND stuff, but not genassym.o.
genassym.o: $S/machine/$P/$M/genassym.c forwarding-headers
Fixes the latter. I'll try some more things later on, but this appears
to work. I'll see what the minimum required is (maybe just the
additional dependency on the forwarding-headers target for genassym.o is
enough), and then commit that if no objections arise.

Pardon me, but I was mistaken here. BEFORE_DEPEND are not a problem, it
was just that the output on console was confusing.
This is enough. I'll commit right away.
