Running test with the stage-1 compiler

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? Thanks Simon
