Hi all, How is a test case supposed to be marked if it makes use of the RTS linker which itself is not supported on some architectures? For example, some test cases are marked for a particular architecutre like PowerPC64 that it fails because of a missing RTS linker. Style (A) test('T10052', [when(arch('powerpc64') or arch('powerpc64le'), expect_broken(11259)), req_interp], makefile_test, ['T10052']) Whereas another test case is marked to be skipped if RTS linker is missing. Style (B) test('static-plugins', [extra_files(['simple-plugin/']), unless(config.have_RTS_linker, skip), expect_broken_for(16803, prof_ways), extra_run_opts('"' + config.libdir + '"')], compile_and_run, ['-package ghc -isimple-plugin/']) If style (A) is the way to go, then for every architecture which does not support the RTS linker a when-clause must be added. If style (B) is the way to go, then shouldn't we change all test cases of style (A) to style (B)? Personally I prefer style (B) over (A) because it makes it easier to add an architecture where the RTS linker is not provided. Even if the RTS linker is provided after some time, then the test case must not be changed. Once PowerPC64 supports the RTS linker all when-clauses must be removed. Any thoughts which style to use?
