Yes, but as Sylvain noted, the configure step (which generates ghc.cabal
and so is particularly sensitive to changes in module structure) is not
tracked by hadrian at the moment. We could in principle fix this, and
as also noted by Sylvain this will become much easier once Make no longer
exists.

But *any* commit could involve such a change. Isn't it a goal of Hadrian
to respond to, well, changes? For example, it is clever enough to rebuild
Hadrian itself when it changes.
It's a bit unsatisfying to say "it'll usually work, but if anything strange
happens, just make clean and try again". Understandable perhaps, but not
satisfying.

Hi Simon,
You have to re-run `./configure` in cases like this. It's because
`compiler/ghc.cabal` is generated from `compiler/ghc.cabal.in` by
`./configure`. This isn't tracked by Hadrian.

Hopefully when `make` build system will be removed it should be easy to
make Hadrian (instead of `./configure`) generate and track this file. In
fact I already did this in a MR more than a year ago but it was blocked on
make-removal.

I am working on a branch of GHC, actually on !8210. I have rebased on
master. Then I say
hadrian/build
and I get the log below. It falls over saying
No generator for _build/stage0/compiler/build/GHC/Unit/Module/Name.hs.
Surely that should not happen?
I'll try make clean; but isn't this a bug?
