// SANITIZER(NAME, ID)

// The first value is the name of the sanitizer as a string. The sanitizer can
// be enabled by specifying -fsanitize=NAME.

// The second value is an identifier which can be used to refer to the
// sanitizer.


// SANITIZER_GROUP(NAME, ID, ALIAS)

// The first two values have the same semantics as the corresponding SANITIZER
// values. The third value is an expression ORing together the IDs of individual
// sanitizers in this group.
