| hadrian/build.cabal.sh --flavor=validate --build-root=_buildvalidate | --test-compiler=_buildvalidate/stage0/bin/ghc | | Although I'll admit this is far from convenient. I often want to do this in a single testsuite directory, or perhaps just on a single test, like say T15043 in testsuite/tests/typecheck/should_compile. I'm not validating at all ... I just want to run a test, or a directory-full of tests, with the stage1 compiler. How can I do that?
