Numerous x86 test cases have been updated to explicitly specify generic tuning using the -mtune=generic flag. This change addresses issues where tests fail when compiled with non-default CPU or tuning settings, typically because they rely on specific code generation patterns observed with generic tuning. By ensuring these tests run with generic tuning, their behavior becomes predictable and consistent, preventing failures related to specialized microarchitecture optimizations.
