Fixed.  I do not plan to add any other attributes at the moment.

[Bug sanitizer/58411] no_sanitize_undefined function attribute

--- Comment #3 from Jan Smets  ---
Eg, these attributes are useful too I think:

no_sanitize => disable ALL sanitize checks
sanitize -> enable ALL sanitize checks

no_sanitize_{address,undefined,vla...} => disable the specific check
sanitize_{address,undefined,vla...} => enable the specific check

Perhaps the enablers will not be used as much, but it might be useful for
people who want to instrument just one specific function.

The no_sanitize attribute could be used for sensitive code, eg, task scheduler
code, interrupt handlers where someone might choose to never instrument.

Thanks
- Jan

Please also think of the other -fsanitize= options.
