Member Enumeration Documentation

AttrKind

enum llvm::Attribute::AttrKind

This enumeration lists the attributes that can be associated with parameters, function results, or the function itself.

Note: The ‘uwtable’ attribute is about the ABI or the user mandating an entry in the unwind table. The ‘nounwind’ attribute is about an exception passing by the function.

In a theoretical system that uses tables for profiling and SjLj for exceptions, they would be fully independent. In a normal system that uses tables for both, the semantics are:

nil = Needs an entry because an exception might pass by. nounwind = No need for an entry uwtable = Needs an entry because the ABI says so and because an exception might pass by. uwtable + nounwind = Needs an entry because the ABI says so.

Enumerator
None	No attributes have been set.
EndAttrKinds	Sentinal value useful for loops.
EmptyKey	Use as Empty key for DenseMap of AttrKind.
TombstoneKey	Use as Tombstone key for DenseMap of AttrKind.
