A test which cannot apply here is then not run at all, ratherthan running in order to announce that it did not.Layout does this better than a declaration would. There is no x86_only(),and no lookup letting a fixtures/<arch>/ file shadow a generic one of thesame name -- an arch-specific test simply carries its own fixtures.Compilers cannot work the same way: CI varies CC over the same tree, so acompiler requirement stays a declaration in the test.What a run leaves out is reported once: # not run: 5 tests in x86/ (this run is arm64)Silence would have been cheaper and wrong. A run covering less than thetree holds must not look like a run that covered all of it.Signed-off-by: Song Liu <song@kernel.org>Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org>Signed-off-by: Ingo Molnar <mingo@kernel.org>Assisted-by: Claude:claude-opus-5Link: https://patch.msgid.link/20260916184351.2720310-4-song@kernel.org List of files: /linux/tools/objtool/tests/generic/fixtures/basic.c Wed, 16 Sep 2026 20:42:56 +0200 Song Liu <song@kernel.org>
