From d76312b8a1f69be71ec38d04d69fbcdd0520ff89 Mon Sep 17 00:00:00 2001 From: Song Liu Date: Wed, 16 Sep 2026 11:42:56 -0700 Subject: objtool/klp: Group the klp tests by architecture Which architecture a test is for is expressed by where it lives: tests are in generic/ or in a directory named for their architecture, each carrying its own fixtures, and the runner executes generic/ plus the one that matches. A test which cannot apply here is then not run at all, rather than 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// file shadow a generic one of the same name -- an arch-specific test simply carries its own fixtures. Compilers cannot work the same way: CI varies CC over the same tree, so a compiler 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 the tree holds must not look like a run that covered all of it.
