Since its introduction (behind a compile-time flag), conservative stack scanning was disabled by default on tests. This CL inverts this logic, enabling CSS by default for all tests that do not define an explicit scope to disable it. Bug: v8:13257 Change-Id: I5ea4249d02f69b0b1e195415c2562daf5d8c0ea9 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/4100912 Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> Commit-Queue: Nikolaos Papaspyrou <nikolaos@chromium.org> Cr-Commit-Position: refs/heads/main@{#84848}
