Public Member Functions

 AttributeSet ()
AttributeSet addAttribute (LLVMContext &C, unsigned Index, Attribute::AttrKind Attr) const
 Add an attribute to the attribute set at the given index. Since attribute sets are immutable, this returns a new set.
AttributeSet addAttribute (LLVMContext &C, unsigned Index, StringRef Kind) const
 Add an attribute to the attribute set at the given index. Since attribute sets are immutable, this returns a new set.
AttributeSet addAttributes (LLVMContext &C, unsigned Index, AttributeSet Attrs) const
 Add attributes to the attribute set at the given index. Since attribute sets are immutable, this returns a new set.
AttributeSet removeAttribute (LLVMContext &C, unsigned Index, Attribute::AttrKind Attr) const
 Remove the specified attribute at the specified index from this attribute list. Since attribute lists are immutable, this returns the new list.
AttributeSet removeAttributes (LLVMContext &C, unsigned Index, AttributeSet Attrs) const
 Remove the specified attributes at the specified index from this attribute list. Since attribute lists are immutable, this returns the new list.

void * getRawPointer () const
 Return a raw pointer that uniquely identifies this attribute list.
bool isEmpty () const
 Return true if there are no attributes.
