Proposal: Move GHC testsuite tests in submodules into GHC
Currently there are a few core libraries which have tests which are run by GHC's testsuite driver. This is inconvenient as changes in these tests require awkward cross-repository changes. Moreover, these tests do little to help correctness as the libraries' upstreams generally don't use GHC's testsuite driver in their own validation pipelines.
I propose that we begin moving the follow sets of tests from their respective repositories into testsuite/tests/libraries/...
:
libraries/process/tests
libraries/parallel/tests
libraries/Win32/tests
