Enumeration Type Documentation

◆ PointerDeclaratorKind

enum PointerDeclaratorKind
strong

Describes the kind of a pointer a declarator describes.

Definition at line 3503 of file SemaType.cpp.

◆ PointerWrappingDeclaratorKind

Describes a declarator chunk wrapping a pointer that marks inference as unexpected.

Definition at line 3521 of file SemaType.cpp.

◆ QualifiedFunctionKind

Kinds of declarator that cannot contain a qualified function type.

C++98 [dcl.fct]p4 / C++11 [dcl.fct]p6: a function type with a cv-qualifier or a ref-qualifier can only appear at the topmost level of a type.

Parens and member pointers are permitted. We don't diagnose array and function declarators, because they don't allow function types at all.

The values of this enum are used in diagnostics.

Definition at line 1901 of file SemaType.cpp.

◆ SimplePointerKind

enum SimplePointerKind
strong

A simple notion of pointer kinds, which matches up with the various pointer declarators.

Definition at line 3452 of file SemaType.cpp.

◆ TypeAttrLocation

The location of a type attribute.

Enumerator
TAL_DeclSpec 

The attribute is in the decl-specifier-seq.

TAL_DeclChunk 

The attribute is part of a DeclaratorChunk.

TAL_DeclName 

The attribute is immediately after the declaration's name.

HandleNeonVectorTypeAttr - The "neon_vector_type" and "neon_polyvector_type" attributes are used to create vector types that are mangled according to ARM's ABI.

Otherwise, these types are identical to those created with the "vector_size" attribute. Unlike "vector_size" the argument to these Neon attributes is the number of vector elements, not the vector size in bytes. The vector width and element type must match one of the standard Neon vector types.

HandleVectorSizeAttribute - this attribute is only applicable to integral and float scalars, although arrays, pointers, and function return values are allowed in conjunction with this construct.

Aggregates with this attribute are invalid, even if they are of the same size as a corresponding scalar. The raw attribute should contain precisely 1 argument, the vector size for the variable, measured in bytes. If curType and rawAttr are well formed, this routine will return a new vector type.

Returns true if any of the declarator chunks before endIndex include a level of indirection: array, pointer, reference, or pointer-to-member.

Because declarator chunks are stored in outer-to-inner order, testing every chunk before endIndex is testing all chunks that embed the current chunk as part of their type.

It is legal to pass the result of Declarator::getNumTypeObjects() as the end index, in which case all chunks are tested.
