For example, - - tc093_HC_OPTS = -noC -ddump-tc - --noC tells not bother generating any C (not point in doing that, since we -only want to test the typechecker). -ddump-tc tells ghc to dump the -typechecker state. - -Depending on the tests/ subdirectory, a default exit code is -expected from all tests therein, normally 0 (==success). -Per-file options to the runtests script can be set as follows - - tc093_RUNTEST_OPTS = -x 1 - -telling the test script that the compiler is expected to fail -on tc093. - -"touch" the file tc093.stderr. "make tc093.o" will then run -the compiler and fail (because the expected output doesn't match the empty -tc093.stderr). However, it is then easy to update tc093.stderr with the -stuff printed out during "make tc093.o".
