What I aim for is to have a fast/short way of doing some experimental changes and running only the containers testsuite with my own changes included. How do I get to doing this?
I don’t think the Makefile works outside the ghc tree.
The testsuite works outside of a GHC tree, although for the tests that are in libraries/*/tests you need to arrange things so that the driver can be found.
However, the HEAD testsuite driver is designed to be used with the HEAD, so may need tweaking to work with older compilers. In this case, the -fno-ghci-history flag isn't supported by any released version yet.
I fixed that in the testsuite a few days ago, so the latest testsuite should work with older GHCs again. It's often useful to be able to say make TEST_HC=ghc-7.0.4 TEST=... to make sure that your new regression test case does indeed fail as it should with the older compiler. Cheers, Simon
