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.

hasOuterPointerLikeChunk()

static bool hasOuterPointerLikeChunk ( const Declarator &  D, unsigned  endIndex  )

static

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.
