Member Enumeration Documentation

ARM8_3Key

enum clang::PointerAuthSchema::ARM8_3Key : unsigned

strong

Discrimination

enum clang::PointerAuthSchema::Discrimination : unsigned

strong

Forms of extra discrimination.

Enumerator
None	No additional discrimination.
Type	Include a hash of the entity's type.
Decl	Include a hash of the entity's identity.
Constant	Discriminate using a constant value.
