Remove the no_sanitize attribute in favor of sanitize This removes the #[no_sanitize] attribute, which was behind an unstable feature named no_sanitize. Instead, we introduce the sanitize attribute which is more powerful and allows to be extended in the future (instead of just focusing on turning sanitizers off). This also makes sanitize(kernel_address = ..) attribute work with -Zsanitize=address To do it the same as how clang disables address sanitizer, we now disable ASAN on sanitize(kernel_address = "off") and KASAN on sanitize(address = "off"). The same was added to clang in https://reviews.llvm.org/D44981. 2025-06-18 13:47:44 +00:00			`#![feature(no_sanitize)] //~ ERROR feature has been removed`

Implement the #[sanitize(..)] attribute This change implements the #[sanitize(..)] attribute, which opts to replace the currently unstable #[no_sanitize]. Essentially the new attribute works similar as #[no_sanitize], just with more flexible options regarding where it is applied. E.g. it is possible to turn a certain sanitizer either on or off: `#[sanitize(address = "on\|off")]` This attribute now also applies to more places, e.g. it is possible to turn off a sanitizer for an entire module or impl block: ```rust \#[sanitize(address = "off")] mod foo { fn unsanitized(..) {} #[sanitize(address = "on")] fn sanitized(..) {} } \#[sanitize(thread = "off")] impl MyTrait for () { ... } ``` This attribute is enabled behind the unstable `sanitize` feature. 2025-06-18 12:53:34 +00:00			`#[sanitize(address = "on")]`
