问题
Sorry for the very simple question, couldn't find a googleable answer.
Is this declaration syntax:
__declspec(align(16)) float rF[4];
__declspec(align(16)) float gF[4];
__declspec(align(16)) float bF[4];
Equivalent to this:
__declspec(align(16)) float rF[4], gF[4], bF[4];
Or will only the first variable be aligned in the latter syntax?
If it matters, these are local variables inside a global method.
回答1:
Yes. A __declspec
is part of the storage class and applies to all declarators in the declaration.
