class AttributeSet

Declaration

class AttributeSet { /* full declaration omitted */ };

Description

This class holds the attributes for a particular argument, parameter, function, or return value. It is an immutable value type that is cheap to copy. Adding and removing enum attributes is intended to be fast, but adding and removing string or integer attributes involves a FoldingSet lookup.

Methods

AttributeSet(const llvm::AttributeSet&)

Declared at: llvm/include/llvm/IR/Attributes.h:231

Parameters

const llvm::AttributeSet& 

AttributeSet()

Description

AttributeSet is a trivially copyable value type.

Declared at: llvm/include/llvm/IR/Attributes.h:230

llvm::AttributeSet addAttribute(
    llvm::LLVMContext& C,
    Attribute::AttrKind Kind) const

Description

Add an argument attribute. Returns a new set because attribute sets are immutable.

Declared at: llvm/include/llvm/IR/Attributes.h:242

Parameters

llvm::LLVMContext& C
Attribute::AttrKind Kind

llvm::AttributeSet addAttribute(
    llvm::LLVMContext& C,
    llvm::StringRef Kind,
    llvm::StringRef Value =
        llvm::StringRef()) const

Description

Add a target-dependent attribute. Returns a new set because attribute sets are immutable.

Declared at: llvm/include/llvm/IR/Attributes.h:247

Parameters

llvm::LLVMContext& C
llvm::StringRef Kind
llvm::StringRef Value = llvm::StringRef()

llvm::AttributeSet addAttributes(
