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 addAttribute (LLVMContext &C, unsigned Index, StringRef Kind, StringRef Value) const
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.
LLVMContextgetContext () const
 Retrieve the LLVM context.
AttributeSet getParamAttributes (unsigned Index) const
 The attributes for the specified index are returned.
AttributeSet getRetAttributes () const
 The attributes for the ret value are returned.
AttributeSet getFnAttributes () const
 The function attributes are returned.
bool hasAttribute (unsigned Index, Attribute::AttrKind Kind) const
 Return true if the attribute exists at the given index.
bool hasAttribute (unsigned Index, StringRef Kind) const
 Return true if the attribute exists at the given index.
bool hasAttributes (unsigned Index) const
 Return true if attribute exists at the given index.
bool hasAttrSomewhere (Attribute::AttrKind Attr) const
 Return true if the specified attribute is set for at least one parameter or for the return value.
Attribute getAttribute (unsigned Index, Attribute::AttrKind Kind) const
 Return the attribute object that exists at the given index.
Attribute getAttribute (unsigned Index, StringRef Kind) const
 Return the attribute object that exists at the given index.
unsigned getParamAlignment (unsigned Index) const

std::string getAsString (unsigned Index, bool InAttrGrp=false) const
 Return the attributes at the index as a string.
iterator begin (unsigned Slot) const
iterator end (unsigned Slot) const
bool operator== (const AttributeSet &RHS) const
 operator==/!= - Provide equality predicates.
bool operator!= (const AttributeSet &RHS) const
uint64_t Raw (unsigned Index) const
void * getRawPointer () const
 Return a raw pointer that uniquely identifies this attribute list.
bool isEmpty () const
 Return true if there are no attributes.
unsigned getNumSlots () const
 Return the number of slots used in this attribute list. This is the number of arguments that have an attribute set on them (including the function itself).
unsigned getSlotIndex (unsigned Slot) const
 Return the index for the given slot.
AttributeSet getSlotAttributes (unsigned Slot) const
 Return the attributes at the given slot.
void dump () const
