I have some number of test programs that I compile and run as usual. I also want to run them using GHCi, with -fobject-code. So I tried this: def just_ghci( name, opts ): opts.only_ways = ['ghci'] test('unboxedsums1.ghci', just_ghci, compile_and_run, ['-fobject-code']) Now, I don't have a file named `unboxedsums1.ghci.hs`, I want to use `unboxedsums1.hs` and I already have a test named `unboxedsums1`. Any ideas how to do this? Thanks
