For what it's worth, there's a "shortcut" to save a few keystrokes:
--test-compiler=stage1
But this broke at some point in the past few months, as documented in
#17528. I am however working on a patch to make this work.

Apparently 'sh validate' now uses Hadrian.
This has broken one of my workflows:
* build the stage1 compiler
* cd testsuite/tests
* make stage=1
That is, run the testsuite with the stage-1 compile. (This often produces a
small test case for a compiler crash, much easier than debugging GHC compiling
itself.)
How do I do this?
I suspect (but have not tested) that you can accomplish this with
hadrian/build.cabal.sh --flavor=validate --build-root=_buildvalidate
--test-compiler=_buildvalidate/stage0/bin/ghc
Although I'll admit this is far from convenient. If you weren't using
the `validate` script this would just be
hadrian/build.cabal.sh --test-compiler=_build/stage0/bin/ghc
Cheers,
